Big Data Analytics Techniques

Many e-commerce companies may incorporate various data analytics techniques to achieve their desired goals. In this section, we will review several of these techniques to understand how they can help improve overall business operations.

Data Mining

Data mining is the process of gathering and analyzing data to reveal information regarding market trends, patterns, and correlations. It helps brands make more informed pricing, campaign, and product inventory decisions.

Data mining employs various analytics techniques, such as clustering, classification, decision trees, and association rules:

• Clustering involves grouping items with similar characteristics.
• Classification is used to categorize items based on their specific characteristics or features.
• Decision trees are diagrams that predict an outcome by splitting data into distinct traits.
• Association rules identify the relationships between items that are frequently found together in transactions.

Moreover, data mining is also useful for forecasting future demand. This gives businesses a head start to stock up on products during demand surges and avoid overstocking during downturns.

Regression Analysis

Regression analysis employs statistical methods to understand the characteristics of a dependent variable and various sets of independent variables.

For eCommerce business owners, regression analysis helps identify the relationship between customer behavior and product features. It can also create predictions about future outcomes by analyzing historical consumer data.

• Multiple linear regression adds more variables to the equation.
• Nonlinear regressions analyze more complex data sets with multiple independent variables.

Machine Learning

Machine learning is a subset of artificial intelligence that deals with algorithms. It is designed to learn from and make predictions on data. It works using various techniques, such as supervised learning, unsupervised learning, and reinforcement learning.

These machine-learning techniques have different purposes and functions. Below is a brief explanation of the three techniques:

• Supervised learning uses labeled data to teach a model how to classify new data points.
• Unsupervised learning identifies patterns and clusters within the data points using unlabeled data.
• Reinforcement learning utilizes rewards as feedback to find the optimal solution for a given problem.

Machine learning algorithms can also predict customer preferences more accurately than traditional methods. Therefore, online businesses can deliver more relevant content and products to their customers.

Moreover, it can also help identify fraud cases by analyzing large transaction data sets. Many companies, such as PayPal, use machine learning models to detect fraudulent activities by identifying patterns from previous fake transactions.
