Unleash the power of your data and make data-driven decisions

The process of data analysis: Understanding with an example

The data analysis process can vary from task to task and company to company. However, for the sake of better comprehension, we are presenting a generic data analysis process followed by most data analysts.

Problem definition

This initial step involves clearly defining the problem or objective of the analysis. Understanding the context, goals, and requirements is important to ensure that the analysis aligns with the desired outcomes. For example, let’s consider a retail company that wants to analyze customer purchase data to identify factors influencing customer churn. The problem is defined as understanding the drivers of customer churn and developing strategies to reduce it.

Data collection

Once the problem is defined, move on to gathering relevant data. In our example, the retail company collects data on customer purchases, demographics, loyalty program participation, customer complaints, and other relevant information. The data can be gathered from several sources such as transactional databases, customer relationship management (CRM) systems, or surveys. It’s important to ensure the data collected is of good quality, relevant to the problem and covers an appropriate time period.

Data cleaning and preprocessing

Raw data often contains errors, missing values, duplicates, or inconsistencies, which must be addressed in this step. Data cleaning involves handling missing data by imputing or removing it based on the analysis requirements. Duplicate records are identified and removed to avoid biases. In our example, data cleaning may involve identifying missing values in customer demographic information and deciding how to handle them, such as imputing missing values based on other available data.

Exploratory Data Analysis (EDA)

EDA involves exploring and understanding the data through summary statistics, visualizations, and descriptive analysis techniques. This step helps uncover patterns, relationships, and insights within the data. In our example, EDA may involve:

  • Analyzing customer churn rates based on different customer segments.
  • Visualizing purchase patterns over time.
  • Identifying correlations between customer complaints and churn.

Data modeling and analysis

In this step, statistical or machine learning models are built to analyze the data, answer specific questions, or make predictions. Depending on the problem, regression, classification, clustering, or time series analysis techniques can be used. In our example, a classification model like logistic regression or a decision tree can be built to predict customer churn based on customer attributes, purchase history, and other relevant factors.

Data modeling and analysis

Interpretation and insights

After analyzing the data and running the models, it’s crucial to interpret the results and derive meaningful insights. This involves understanding the implications of the findings of the analysis in the context of the problem and making data-driven recommendations. In our example, the interpretation could involve identifying key factors contributing to customer churns, such as low purchase frequency or recent negative customer interactions, and recommending targeted retention strategies to address these factors.

Communication and visualization

Once the insights are derived, it’s essential to communicate the findings to stakeholders effectively. Visualizations, reports, dashboards, or presentations can be used to present the analysis results clearly and understandably. In our example, visualizations can be created to showcase churn rates across different customer segments or demonstrate specific factors’ impact on churn probability.

Iteration and refinement

The data analysis process is often iterative, requiring refinement and improvement. This step involves reviewing the analysis process, evaluating model performance, and incorporating feedback to enhance the analysis. It may also involve revisiting earlier steps to gather additional data or modifying the analysis approach based on new insights or requirements.

Data analysis vs. data science

Data analysis and data science are related fields that involve working with data to gain insights and make informed decisions. While there is some overlap between both, they have distinct focuses and approaches.

Data analysis encompasses the systematic examination, cleansing, transformation, and modeling of data to uncover valuable insights, make informed conclusions, and facilitate decision-making processes. It involves using various statistical and analytical techniques to explore data, identify patterns, and extract insights. Data analysts typically work with structured data and employ tools such as spreadsheets, SQL, and statistical software to perform their analyses. Their primary goal is to understand historical data and provide insights based on past trends and patterns.

Data science, on the contrary, is a broader and more interdisciplinary field that encompasses data analysis and other areas such as machine learning, statistics, and computer science Data scientists not only analyze data but also develop and deploy predictive models, build data pipelines, and create algorithms to solve complex problems. They work with large and often unstructured datasets, utilize advanced analytics techniques, and strongly focus on developing and implementing data-driven solutions. Data science involves a combination of programming skills, mathematical/statistical knowledge, and domain expertise to extract valuable insights and drive decision-making.

Hence, data analysis is a subset of data science that focuses on extracting insights and making decisions based on historical data using statistical and analytical techniques. Data science, on the other hand, encompasses a broader set of skills and techniques, including data analysis, machine learning, and algorithm development, to solve complex problems and derive actionable insights from data.

Machine learning in data science

In data science, machine learning is used to extract valuable insights and patterns from large volumes of data, automate processes, and make accurate predictions or classifications.

Here are some key concepts and techniques in machine learning that are frequently used in data science:

  1. Supervised learning: This is a subcategory of ML where AI models are trained on labeled data, meaning the input data is accompanied by corresponding output labels or target variables. The model learns from the labeled examples and can make predictions or classifications on unseen data.
  2. Unsupervised learning: Contrary to supervised learning, unsupervised learning involves training models on unlabeled data. The aim is to discover patterns, structures, or relationships within the data without explicit target variables. Clustering and dimensionality reduction are common unsupervised learning techniques.
  3. Regression: Regression models are used when the target variable is continuous and aims to predict a numeric value. Linear, polynomial, and decision tree regression are common regression techniques.
  4. Classification: Classification is used when the target variable is categorical, and the goal is to assign data points to predefined classes or categories. Examples include logistic regression, decision trees, random forests, and Support Vector Machines (SVM).
  5. Clustering: Clustering algorithms group similar data points together based on their inherent characteristics or similarities. K-means clustering and hierarchical clustering are popular clustering techniques used in data science.
  6. Dimensionality reduction: When dealing with high-dimensional data, dimensionality reduction techniques are employed to reduce the number of features while preserving essential information. Principal Component Analysis (PCA) and t-SNE (t-Distributed Stochastic Neighbor Embedding) are widely used dimensionality reduction methods.
  7. Deep learning: Deep learning is a specialized branch of machine learning that relies on the utilization of artificial neural networks. These networks draw inspiration from the intricate structure and functioning of the human brain. Deep learning encompasses sophisticated neural networks such as Recurrent Neural Networks (RNNs) and Convolutional Neural Networks (CNNs) that can automatically learn hierarchical representations from complex data like images, text, and time series.
  8. Ensemble methods: Combining multiple models to improve prediction accuracy and robustness. Bagging (e.g., random forests) and boosting (e.g., AdaBoost, gradient boosting) are the two most commonly used ensemble methods.
  9. Feature engineering: Feature engineering involves selecting, transforming, and creating meaningful features from raw data to improve the performance of machine learning models. It is a critical step in data preprocessing and can significantly impact model effectiveness.
  10. Evaluation and validation: To assess the performance of machine learning models, various evaluation metrics like accuracy, precision, recall, and F1 score are used. Validation techniques such as cross-validation and train-test splits are employed to estimate how well a model generalizes to unseen data.

Data analysis workflow using Scikit-learn

Let us guide you through a concise data analysis workflow using the scikit-learn Python library. The process comprises three key steps: data preprocessing, model selection and training, parameter tuning, and model evaluation. Let us go through each step to understand the data analysis workflow in detail.

Data preprocessing

This step involves selecting relevant features, normalizing the data, and ensuring class balance. These techniques help prepare the data for effective analysis.

Load the dataset

First, we need to load the dataset that we need to analyze.

To begin the analysis, we will load the dataset using the Pandas library in Python. For this demonstration, we will use the heart.csv dataset, which is available in the Kaggle repository. This dataset will serve as our foundation for the analysis.

import pandas as pd

df = pd.read_csv('source/heart.csv')
df.head()
If you want to  retrieve the dimensions or shape of the DataFrame, you can run the following code:
df.shape

Features selection

Next, we split the dataset’s columns into input (X) and output (Y) variables. In this step, we assign all the columns except the output column as the input features.

features = []
for column in df.columns:
if column != 'output':
features.append(column)
features
X = df[features]
Y = df['output']

To determine the minimum set of input features, we employ the pandas DataFrame’s corr() function to calculate the Pearson correlation coefficient among the features. This coefficient helps identify the strength and direction of the linear relationship between pairs of features. By analyzing these correlations, we can determine which features are most strongly correlated and select a reduced set of input features for further analysis.

X.corr()

Data normalization

Run the following to generate descriptive statistics of the DataFrame.

X.describe()

Next, we can perform data normalization using the MinMaxScaler() function from the scikit-learn library and store the scaled values in the corresponding columns of the DataFrame X. Before applying the scaler, it is necessary to fit it to the data using the fit() function. Once fitted, the transformation can be applied using the transform() function. It’s important to note that the input data must be reshaped into the format (-1,1) before passing it as an input parameter to the scaler.

from sklearn.preprocessing import MinMaxScaler

for column in X.columns:
feature = np.array(X[column]).reshape(-1,1)
scaler = MinMaxScaler()
scaler.fit(feature)
feature_scaled = scaler.transform(feature)
X[column] = feature_scaled.reshape(1,-1)[0]

Next, you can run the code ‘X.describe()’ again to view the normalized data.

Split the dataset into training and test sets

Now, we proceed to split the dataset into two components: a training and a test set. The test set will account for 20% of the entire dataset. To accomplish this, we utilize the train_test_split() function provided by scikit-learn.

By splitting the data in this manner, we can use the training set to train our model, allowing it to learn patterns and relationships within the data. Subsequently, we can assess the performance of the trained model on the test set, which contains unseen data. This evaluation will help us understand how well the model generalizes to new data and provides insights into its overall performance.

import numpy as np
from sklearn.model_selection import train_test_split

X_train, X_test, y_train, y_test = train_test_split( X, Y, test_size=0.20, random_state=42)

Balancing

Next, verify whether the dataset is balanced by examining the representation of output classes in the training set. We aim to determine if the classes are equally represented or if there is an imbalance. To achieve this, we utilize the value_counts() function, which calculates the number of records in each output class.

y_train.value_counts()

If the output classes are not balanced, balance it using imblearn library

from imblearn.over_sampling import RandomOverSampler
over_sampler = RandomOverSampler(random_state=42)
X_bal_over, y_bal_over = over_sampler.fit_resample(X_train, y_train)

Calculate the number of records in each class using the value_counts() function, which allows us to determine the distribution of samples across different classes.

y_bal_over.value_counts()

Next, do the under sampling via the RandomUnderSampler() model.

from imblearn.under_sampling import RandomUnderSampler

under_sampler = RandomUnderSampler(random_state=42)
X_bal_under, y_bal_under = under_sampler.fit_resample(X_train, y_train)
y_bal_under.value_counts()

Model selection and training

Here, we explore different machine learning models to select the one apt for the specific purpose. We would be moving forward with the KNeighborsClassifier model and training them firstly with the imbalanced data.

from sklearn.neighbors import KNeighborsClassifier

model = KNeighborsClassifier(n_neighbors=3)
model.fit(X_train, y_train)
y_score = model.predict_proba(X_test)

Next, calculate the performance of the model, especially the roc_curve() and the precision_recall() and then plot them.

import matplotlib.pyplot as plt
from sklearn.metrics import roc_curve
from scikitplot.metrics import plot_roc,auc
from scikitplot.metrics import plot_precision_recall

fpr0, tpr0, thresholds = roc_curve(y_test, y_score[:, 1])

# Plot metrics 
plot_roc(y_test, y_score)
plt.show()

plot_precision_recall(y_test, y_score)
plt.show()

Next, recalculate the same using oversampling for balancing the data. The following codes help assess the model’s performance and evaluate its ability to discriminate between different classes.

model = KNeighborsClassifier(n_neighbors=3)
model.fit(X_bal_over, y_bal_over)
y_score = model.predict_proba(X_test)
fpr0, tpr0, thresholds = roc_curve(y_test, y_score[:, 1])

# Plot metrics 
plot_roc(y_test, y_score)
plt.show()

plot_precision_recall(y_test, y_score)
plt.show()

Lastly, we train the model using under-sampled data, where instances from the majority class are reduced to match the number of instances in the minority class.

model = KNeighborsClassifier(n_neighbors=3)
model.fit(X_bal_under, y_bal_under)
y_score = model.predict_proba(X_test)
fpr0, tpr0, thresholds = roc_curve(y_test, y_score[:, 1])

# Plot metrics 
plot_roc(y_test, y_score)
plt.show()

plot_precision_recall(y_test, y_score)
plt.show()

Parameter tuning and model evaluation

Finally, we need to enhance the performance of the model by searching for the best parameters. To accomplish this, we utilize the GridSearchCV mechanism provided by the scikit-learn library.

from sklearn.model_selection import GridSearchCV

model = KNeighborsClassifier()

param_grid = {
'n_neighbors': np.arange(2,8),
'algorithm' : ['auto', 'ball_tree', 'kd_tree', 'brute'],
'metric' : ['euclidean','manhattan','chebyshev','minkowski']
}

grid = GridSearchCV(model, param_grid = param_grid)
grid.fit(X_train, y_train)


best_estimator = grid.best_estimator_
best_estimator

With the best estimator in hand, we proceed to evaluate the algorithm’s performance. This involves using the model to predict the test set, calculate ROC curve metrics, and then visualize the ROC and precision-recall curves using the provided plotting functions. These steps allow for assessing the model’s performance and provide insights into its ability to discriminate between different classes.

best_estimator.fit(X_train, y_train)
y_score = best_estimator.predict_proba(X_test)
fpr0, tpr0, thresholds = roc_curve(y_test, y_score[:, 1])

plot_roc(y_test, y_score)
plt.show()

plot_precision_recall(y_test, y_score)
plt.show()

Iterate this evaluation step repeatedly until the model reaches an optimized performance.

You can access the whole set of codes in this GitHub repository.
