Startup, SMB or company founders, managers or decision makers often claim that they are "data rich but information poor". This statement is in many cases only partially correct because it hides a misconception about the data life cycle. The fact that it is data-rich but information-poor suggests that previously untapped data sources are waiting to be exploited and used.

It is very unlikely that any organization will collect data without a particular purpose. In most cases, data is collected to manage operational processes. Collecting data without a particular purpose is a waste of resources. In many companies, once data is used, it is stored and becomes "dark data".

Because almost all operational processes are recorded electronically, data is now everywhere. Managers rightly ask themselves what to do with this information after it has been archived. A strategic approach to data science would help an organization unravel the untapped value of these data stores to better understand their strategic and operational context.

The evolution to become a data-based organization begins with the collection of data generated during operational processes. The next step is to describe this data through exploratory techniques such as visualizations and statistics, which is the domain of traditional business reporting (or what is called today Business Intelligence) that provides insights for decision making.

Once the data has been explored and understood, organizations can diagnose business processes to understand the causal and logical relationships between variables. The penultimate phase consists of using knowledge of the past and its causal and logical connections to predict possible futures and build the desired future. The final stage of the data science journey is a situation where data is used to prescribe everyday operations

This process is not a left to right trip, eventually landing in a place where the algorithms control our destiny, and the rest becomes less critical. This process guides the data science strategy to this point, but forms a strict hierarchy.

Before algorithms can decide anything independently, you need to be able to predict the immediate future. To predict the future, you need to have a good understanding of descriptive statistics to diagnose a business process. Finally, the Garbage-In-Garbage-Out (GIGO) principle requires that analysis is only possible if we understand the data collected.

Towards a Data-driven Organization

The process we have just seen provides a strategic map for organizations trying to be more data-driven. Each step in the process is equally important for the next level because these higher levels of complexity cannot be achieved without embracing the lower levels. The most important aspect of the data science process is that it outlines an evolutionary approach to becoming a data-driven organization.

As an organization evolves into more complex forms of data science, the early stages do not become vestigial appendages, but remain an integral part of the data science strategy. All parts of this model have the same relative value.

However, being driven by data is more than a process of increasing complexity. Evidence-based management requires people within the organization to be knowledgeable about data and to work together toward a common goal.

The systematic aspect of data science requires a formalized process to ensure robust results. The increasing complexity of analytical methods also requires investment in better tools and data infrastructure.

There are many technical aspects to consider when applying data science in an organization. However, simply focusing on the technicalities of data analysis is not enough to create value for an organization. A data science manager needs to manage people, systems, and processes to develop a data-based organization.

Decision makers sometimes ignore even the most useful and aesthetic visualizations, even when the analysis is sound. Data science, using best practices, is only the starting point for creating a value-driven organization. A critical aspect of ensuring that managers use results is to foster a data-based culture, which requires managing people.

To allow data science to flourish, the organization needs to have a well-established set of computer systems to store and analyze data and present results. A wide range of data science tools are available, each of which plays a different role in the analysis value chain.

Each data science project begins with a problem definition that is translated into data and code to define a solution. This problem is injected into the data vortex until a solution is found. The data science process discusses the workflow of creating "data products".

The three aspects of becoming a data-based organization and strategically implementing data science require alignment:

People
Systems and
Processes

This in order to optimize the value that can be extracted from the available information.

1- People

When talking about the people in a data-based organization, we should not only mention the specialists who create the data products. The members of the data science team possess the competencies shown in the following diagram

Source here

These clearly technical people must be able to communicate the results of their work to their colleagues or clients and convince them to apply the findings.

Data science does not only occur exclusively within the specialized team. Every data project has an internal or external client who has a problem that needs an answer. The data science team and the users of their products work together to improve the organization.

This implies that a data scientist needs to understand the basic principles of organizational behavior and change management and be a good communicator. In contrast, recipients of data science need to have sufficient knowledge of the data to understand how to interpret and use the results.

2- Systems

Like any other profession, a data scientist needs an appropriate set of tools to create value from the data. There are a number of data science solutions available on the market, many of which are open source software. There are specialized tools for every aspect of the data science workflow.

There is no need to discuss the multitude of packages that are available. Many excellent websites examine the various offerings. We will instead offer some thoughts on the use of Excel (or any other spreadsheet) versus code writing and business intelligence platforms.

Spreadsheets are a versatile tool for analyzing data that has proliferated in almost every aspect of business. However, this universal tool is not very suitable for undertaking complex and sophisticated data science. One of the perceived advantages of spreadsheets is that they contain the data, code and output in one convenient file. This convenience comes at a price, as it reduces the robustness of the analysis.

Anyone who has ever had the displeasure of reverse engineering a spreadsheet will understand the limitations of spreadsheets. In spreadsheets, it is not immediately clear which cell is the result of another cell and what the original data is.

Many organizations use spreadsheets as the only source of truth for business data, which should be avoided if information needs to be shared. The best practice of data science is to separate the data, the code and the result.

As mentioned above, the best way to create unicorns in data science is to teach experts in the field how to write analytical code. Writing code with R or Python is like writing an instruction manual on how to analyze data. Anyone who understands the language will be able to know how their conclusions are derived.

Modern data science languages can generate print-quality visualizations and can produce results in many formats, including a spreadsheet or standalone application.

The gold standard for programming in data science is well-documented programming. This technique combines code with "pseudocode" (or to make it easier, it is to make comments next to the written code, and thus explain how it was created and what its function is) and thus allow the algorithm to be fully understood. All programming languages include the ability to add these comments.

Each language has its own methods for combining text with code. RMarkdown, Jupyter Notebooks and Org Mode are popular systems for data analysis and allow easy understanding of these comments (even as a blog post with text editing). Once the code is written, at the touch of a button the machine generates a new report with updated statistics and graphics.

Finally, Business Intelligence tools are useful for disseminating the results of a data science project, but are not very useful for detailed analysis. A platform like Power BI is a great system to visualize the result of an analysis because it provides very flexible ways to cut and slice the data and visualize the results. The analytical capabilities of the platform are not very high but can be modified by inserting code in Python or R to complement its capabilities.

3- Processes

The process of creating value from data follows an iterative workflow that works from raw data to a finished project.

The workflow starts with the definition of a problem that needs to be solved as shown in the figure below. The next step involves loading and transforming the data into a format suitable for the required analysis. The data science workflow contains a loop consisting of exploration, modeling, and reflection, which is repeated until the problem is solved or shown to be unsolvable.

Source

The workflow of a data project is independent of the data science continuity aspect being considered. The same principles apply to all types of analysis. For larger projects, formal project management methods are advised to control time, budget, and quality.

Conclusion

As we can see, organizations must make a conscious, informed and organized effort to become a data-based company, which means that they will finally be making decisions without relying on whims, egos, competencies or other characteristics. Instead, strategic and important decisions that generate value are made based on past data, analyzed in the present and it is a matter of predicting a result that favors the continuity and advantages of the company in the market.

On the other hand, we see that the company must change certain internal processes, and have adequate personnel, in order to have a sophisticated and accurate approach to data. If you want more information about how to implement a data science problem we can help you here.

Model Evaluation Metrics in Machine Learning

CreditsPredictive models have become a trusted advisor to many businesses and for a good reason. These models can “foresee the future”, and there are many different methods available, meaning any industry can find one that fits their particular challenges.When we talk about predictive models, we are talking either about a regression model (continuous output) or a classification model (nominal or binary output). In classification problems, we use two types of algorithms (dependent on the kind of output it creates):Class output: Algorithms like SVM and KNN create a class output. For instance, in a binary classification problem, the outputs will be either 0 or 1. However, today we have algorithms that can convert these class outputs to probability.Probability output: Algorithms like Logistic Regression, Random Forest, Gradient Boosting, Adaboost, etc. give probability outputs. Converting probability outputs to class output is just a matter of creating a threshold probability.IntroductionWhile data preparation and training a machine learning model is a key step in the machine learning pipeline, it’s equally important to measure the performance of this trained model. How well the model generalizes on the unseen data is what defines adaptive vs non-adaptive machine learning models.By using different metrics for performance evaluation, we should be in a position to improve the overall predictive power of our model before we roll it out for production on unseen data.Without doing a proper evaluation of the ML model using different metrics, and depending only on accuracy, it can lead to a problem when the respective model is deployed on unseen data and can result in poor predictions.This happens because, in cases like these, our models don’t learn but instead memorize;hence, they cannot generalize well on unseen data.Model Evaluation MetricsLet us now define the evaluation metrics for evaluating the performance of a machine learning model, which is an integral component of any data science project. It aims to estimate the generalization accuracy of a model on the future (unseen/out-of-sample) data.Confusion MatrixA confusion matrix is a matrix representation of the prediction results of any binary testing that is often used to describe the performance of the classification model (or “classifier”) on a set of test data for which the true values are known.The confusion matrix itself is relatively simple to understand, but the related terminology can be confusing.Confusion matrix with 2 class labels.Each prediction can be one of the four outcomes, based on how it matches up to the actual value:True Positive (TP): Predicted True and True in reality.True Negative (TN): Predicted False and False in reality.False Positive (FP): Predicted True and False in reality.False Negative (FN): Predicted False and True in reality.Now let us understand this concept using hypothesis testing.A Hypothesis is speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false.A Null Hypothesis is a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove.We would always reject the null hypothesis when it is false, and we would accept the null hypothesis when it is indeed true.Even though hypothesis tests are meant to be reliable, there are two types of errors that can occur.These errors are known as Type 1 and Type II errors.For example, when examining the effectiveness of a drug, the null hypothesis would be that the drug does not affect a disease.Type I Error:- equivalent to False Positives(FP).The first kind of error that is possible involves the rejection of a null hypothesis that is true.Let’s go back to the example of a drug being used to treat a disease. If we reject the null hypothesis in this situation, then we claim that the drug does have some effect on a disease. But if the null hypothesis is true, then, in reality, the drug does not combat the disease at all. The drug is falsely claimed to have a positive effect on a disease.Type II Error:- equivalent to False Negatives(FN).The other kind of error that occurs when we accept a false null hypothesis. This sort of error is called a type II error and is also referred to as an error of the second kind.If we think back again to the scenario in which we are testing a drug, what would a type II error look like? A type II error would occur if we accepted that the drug hs no effect on disease, but in reality, it did.A sample python implementation of the Confusion matrix.import warnings import pandas as pd from sklearn import model_selection from sklearn.linear_model import LogisticRegression from sklearn.metrics import confusion_matrix import matplotlib.pyplot as plt %matplotlib inline #ignore warnings warnings.filterwarnings('ignore') # Load digits dataset url = "http://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data" df = pd.read_csv(url) # df = df.values X = df.iloc[:,0:4] y = df.iloc[:,4] #test size test_size = 0.33 #generate the same set of random numbers seed = 7 #Split data into train and test set. X_train, X_test, y_train, y_test = model_selection.train_test_split(X, y, test_size=test_size, random_state=seed) #Train Model model = LogisticRegression() model.fit(X_train, y_train) pred = model.predict(X_test) #Construct the Confusion Matrix labels = ['Iris-setosa', 'Iris-versicolor', 'Iris-virginica'] cm = confusion_matrix(y_test, pred, labels) print(cm) fig = plt.figure() ax = fig.add_subplot(111) cax = ax.matshow(cm) plt.title('Confusion matrix') fig.colorbar(cax) ax.set_xticklabels([''] + labels) ax.set_yticklabels([''] + labels) plt.xlabel('Predicted Values') plt.ylabel('Actual Values') plt.show()Confusion matrix with 3 class labels.The diagonal elements represent the number of points for which the predicted label is equal to the true label, while anything off the diagonal was mislabeled by the classifier. Therefore, the higher the diagonal values of the confusion matrix the better, indicating many correct predictions.In our case, the classifier predicted all the 13 setosa and 18 virginica plants in the test data perfectly. However, it incorrectly classified 4 of the versicolor plants as virginica.There is also a list of rates that are often computed from a confusion matrix for a binary classifier:1. AccuracyOverall, how often is the classifier correct?Accuracy = (TP+TN)/totalWhen our classes are roughly equal in size, we can use accuracy, which will give us correctly classified values.Accuracy is a common evaluation metric for classification problems. It’s the number of correct predictions made as a ratio of all predictions made.Misclassification Rate(Error Rate): Overall, how often is it wrong. Since accuracy is the percent we correctly classified (success rate), it follows that our error rate (the percentage we got wrong) can be calculated as follows:Misclassification Rate = (FP+FN)/totalWe use the sklearn module to compute the accuracy of a classification task, as shown below.#import modules import warnings import pandas as pd import numpy as np from sklearn import model_selection from sklearn.linear_model import LogisticRegression from sklearn import datasets from sklearn.metrics import accuracy_score #ignore warnings warnings.filterwarnings('ignore') # Load digits dataset iris = datasets.load_iris() # # Create feature matrix X = iris.data # Create target vector y = iris.target #test size test_size = 0.33 #generate the same set of random numbers seed = 7 #cross-validation settings kfold = model_selection.KFold(n_splits=10, random_state=seed) #Model instance model = LogisticRegression() #Evaluate model performance scoring = 'accuracy' results = model_selection.cross_val_score(model, X, y, cv=kfold, scoring=scoring) print('Accuracy -val set: %.2f%% (%.2f)' % (results.mean()*100, results.std())) #split data X_train, X_test, y_train, y_test = model_selection.train_test_split(X, y, test_size=test_size, random_state=seed) #fit model model.fit(X_train, y_train) #accuracy on test set result = model.score(X_test, y_test) print("Accuracy - test set: %.2f%%" % (result*100.0))The classification accuracy is 88% on the validation set.2. PrecisionWhen it predicts yes, how often is it correct?Precision=TP/predicted yesWhen we have a class imbalance, accuracy can become an unreliable metric for measuring our performance. For instance, if we had a 99/1 split between two classes, A and B, where the rare event, B, is our positive class, we could build a model that was 99% accurate by just saying everything belonged to class A. Clearly, we shouldn’t bother building a model if it doesn’t do anything to identify class B; thus, we need different metrics that will discourage this behavior. For this, we use precision and recall instead of accuracy.3. Recall or SensitivityWhen it’s actually yes, how often does it predict yes?True Positive Rate = TP/actual yesRecall gives us the true positive rate (TPR), which is the ratio of true positives to everything positive.In the case of the 99/1 split between classes A and B, the model that classifies everything as A would have a recall of 0% for the positive class, B (precision would be undefined — 0/0). Precision and recall provide a better way of evaluating model performance in the face of a class imbalance. They will correctly tell us that the model has little value for our use case.Just like accuracy, both precision and recall are easy to compute and understand but require thresholds. Besides, precision and recall only consider half of the confusion matrix:4. F1 ScoreThe F1 score is the harmonic mean of the precision and recall, where an F1 score reaches its best value at 1 (perfect precision and recall) and worst at 0.Why harmonic mean? Since the harmonic mean of a list of numbers skews strongly toward the least elements of the list, it tends (compared to the arithmetic mean) to mitigate the impact of large outliers and aggravate the impact of small ones.An F1 score punishes extreme values more. Ideally, an F1 Score could be an effective evaluation metric in the following classification scenarios:When FP and FN are equally costly — meaning they miss on true positives or find false positives — both impact the model almost the same way, as in our cancer detection classification exampleAdding more data doesn’t effectively change the outcome effectivelyTN is high (like with flood predictions, cancer predictions, etc.)A sample python implementation of the F1 score.import warnings import pandas from sklearn import model_selection from sklearn.linear_model import LogisticRegression from sklearn.metrics import log_loss from sklearn.metrics import precision_recall_fscore_support as score, precision_score, recall_score, f1_score warnings.filterwarnings('ignore') url = "https://raw.githubusercontent.com/jbrownlee/Datasets/master/pima-indians-diabetes.data.csv" dataframe = pandas.read_csv(url) dat = dataframe.values X = dat[:,:-1] y = dat[:,-1] test_size = 0.33 seed = 7 model = LogisticRegression() #split data X_train, X_test, y_train, y_test = model_selection.train_test_split(X, y, test_size=test_size, random_state=seed) model.fit(X_train, y_train) precision = precision_score(y_test, pred) print('Precision: %f' % precision) # recall: tp / (tp + fn) recall = recall_score(y_test, pred) print('Recall: %f' % recall) # f1: tp / (tp + fp + fn) f1 = f1_score(y_test, pred) print('F1 score: %f' % f1)5. SpecificityWhen it’s no, how often does it predict no?True Negative Rate=TN/actual noIt is the true negative rate or the proportion of true negatives to everything that should have been classified as negative.Note that, together, specificity and sensitivity consider the full confusion matrix:6. Receiver Operating Characteristics (ROC) CurveMeasuring the area under the ROC curve is also a very useful method for evaluating a model. By plotting the true positive rate (sensitivity) versus the false-positive rate (1 — specificity), we get the Receiver Operating Characteristic (ROC) curve. This curve allows us to visualize the trade-off between the true positive rate and the false positive rate.The following are examples of good ROC curves. The dashed line would be random guessing (no predictive value) and is used as a baseline; anything below that is considered worse than guessing. We want to be toward the top-left corner:A sample python implementation of the ROC curves.#Classification Area under curve import warnings import pandas from sklearn import model_selection from sklearn.linear_model import LogisticRegression from sklearn.metrics import roc_auc_score, roc_curve warnings.filterwarnings('ignore') url = "https://raw.githubusercontent.com/jbrownlee/Datasets/master/pima-indians-diabetes.data.csv" dataframe = pandas.read_csv(url) dat = dataframe.values X = dat[:,:-1] y = dat[:,-1] seed = 7 #split data X_train, X_test, y_train, y_test = model_selection.train_test_split(X, y, test_size=test_size, random_state=seed) model.fit(X_train, y_train) # predict probabilities probs = model.predict_proba(X_test) # keep probabilities for the positive outcome only probs = probs[:, 1] auc = roc_auc_score(y_test, probs) print('AUC - Test Set: %.2f%%' % (auc*100)) # calculate roc curve fpr, tpr, thresholds = roc_curve(y_test, probs) # plot no skill plt.plot([0, 1], [0, 1], linestyle='--') # plot the roc curve for the model plt.plot(fpr, tpr, marker='.') plt.xlabel('False positive rate') plt.ylabel('Sensitivity/ Recall') # show the plot plt.show()In the example above, the AUC is relatively close to 1 and greater than 0.5. A perfect classifier will have the ROC curve go along the Y-axis and then along the X-axisLog LossLog Loss is the most important classification metric based on probabilities.As the predicted probability of the true class gets closer to zero, the loss increases exponentially:It measures the performance of a classification model where the prediction input is a probability value between 0 and 1. Log loss increases as the predicted probability diverge from the actual label. The goal of any machine learning model is to minimize this value. As such, smaller log loss is better, with a perfect model having a log loss of 0.A sample python implementation of the Log Loss.#Classification LogLoss import warnings import pandas from sklearn import model_selection from sklearn.linear_model import LogisticRegression from sklearn.metrics import log_loss warnings.filterwarnings('ignore') url = "https://raw.githubusercontent.com/jbrownlee/Datasets/master/pima-indians-diabetes.data.csv" dataframe = pandas.read_csv(url) dat = dataframe.values X = dat[:,:-1] y = dat[:,-1] seed = 7 #split data X_train, X_test, y_train, y_test = model_selection.train_test_split(X, y, test_size=test_size, random_state=seed) model.fit(X_train, y_train) #predict and compute logloss pred = model.predict(X_test) accuracy = log_loss(y_test, pred) print("Logloss: %.2f" % (accuracy))Logloss: 8.02 Jaccard IndexJaccard Index is one of the simplest ways to calculate and find out the accuracy of a classification ML model. Let’s understand it with an example. Suppose we have a labeled test set, with labels as –y = [0,0,0,0,0,1,1,1,1,1]And our model has predicted the labels as –y1 = [1,1,0,0,0,1,1,1,1,1]The above Venn diagram shows us the labels of the test set and the labels of the predictions, and their intersection and union.Jaccard Index or Jaccard similarity coefficient is a statistic used in understanding the similarities between sample sets. The measurement emphasizes the similarity between finite sample sets and is formally defined as the size of the intersection divided by the size of the union of the two labeled sets, with formula as –Jaccard Index or Intersection over Union(IoU)So, for our example, we can see that the intersection of the two sets is equal to 8 (since eight values are predicted correctly) and the union is 10 + 10–8 = 12. So, the Jaccard index gives us the accuracy as –So, the accuracy of our model, according to Jaccard Index, becomes 0.66, or 66%.Higher the Jaccard index higher the accuracy of the classifier.A sample python implementation of the Jaccard index.import numpy as np def compute_jaccard_similarity_score(x, y): intersection_cardinality = len(set(x).intersection(set(y))) union_cardinality = len(set(x).union(set(y))) return intersection_cardinality / float(union_cardinality) score = compute_jaccard_similarity_score(np.array([0, 1, 2, 5, 6]), np.array([0, 2, 3, 5, 7, 9])) print "Jaccard Similarity Score : %s" %score passJaccard Similarity Score : 0.375Kolomogorov Smirnov chartK-S or Kolmogorov-Smirnov chart measures the performance of classification models. More accurately, K-S is a measure of the degree of separation between positive and negative distributions.The cumulative frequency for the observed and hypothesized distributions is plotted against the ordered frequencies. The vertical double arrow indicates the maximal vertical difference.The K-S is 100 if the scores partition the population into two separate groups in which one group contains all the positives and the other all the negatives. On the other hand, If the model cannot differentiate between positives and negatives, then it is as if the model selects cases randomly from the population. The K-S would be 0.In most classification models the K-S will fall between 0 and 100, and that the higher the value the better the model is at separating the positive from negative cases.The K-S may also be used to test whether two underlying one-dimensional probability distributions differ. It is a very efficient way to determine if two samples are significantly different from each other.A sample python implementation of the Kolmogorov-Smirnov.from scipy.stats import kstest import random # N = int(input("Enter number of random numbers: ")) N = 10 actual =[] print("Enter outcomes: ") for i in range(N): # x = float(input("Outcomes of class "+str(i + 1)+": ")) actual.append(random.random()) print(actual) x = kstest(actual, "norm") print(x)The Null hypothesis used here assumes that the numbers follow the normal distribution. It returns statistics and p-value. If the p-value is < alpha, we reject the Null hypothesis.Alpha is defined as the probability of rejecting the null hypothesis given the null hypothesis(H0) is true. For most of the practical applications, alpha is chosen as 0.05.Gain and Lift ChartGain or Lift is a measure of the effectiveness of a classification model calculated as the ratio between the results obtained with and without the model. Gain and lift charts are visual aids for evaluating the performance of classification models. However, in contrast to the confusion matrix that evaluates models on the whole population gain or lift chart evaluates model performance in a portion of the population.The higher the lift (i.e. the further up it is from the baseline), the better the model.The following gains chart, run on a validation set, shows that with 50% of the data, the model contains 90% of targets, Adding more data adds a negligible increase in the percentage of targets included in the model.Gain/lift chartLift charts are often shown as a cumulative lift chart, which is also known as a gains chart. Therefore, gains charts are sometimes (perhaps confusingly) called “lift charts”, but they are more accurately cumulative lift charts.It is one of their most common uses is in marketing, to decide if a prospective client is worth calling.Gini CoefficientThe Gini coefficient or Gini Index is a popular metric for imbalanced class values. The coefficient ranges from 0 to 1 where 0 represents perfect equality and 1 represents perfect inequality. Here, if the value of an index is higher, then the data will be more dispersed.Gini coefficient can be computed from the area under the ROC curve using the following formula:Gini Coefficient = (2 * ROC_curve) — 1ConclusionUnderstanding how well a machine learning model is going to perform on unseen data is the ultimate purpose behind working with these evaluation metrics. Metrics like accuracy, precision, recall are good ways to evaluate classification models for balanced datasets, but if the data is imbalanced and there’s a class disparity, then other methods like ROC/AUC, Gini coefficient perform better in evaluating the model performance.Well, this concludes this article.
