2. Introduction to Machine Learning

Machine learning is a subset of artificial intelligence that focuses on building systems that learn from data, identify patterns, and make decisions with minimal human intervention. It plays a pivotal role in enhancing business analytics capabilities.

2.1 Types of Machine Learning

• Supervised Learning: Involves training a model on a labeled dataset, meaning that the output is known.
• Unsupervised Learning: Involves training a model on data without labeled responses, focusing on finding hidden patterns.
• Reinforcement Learning: An area of machine learning where an agent learns to make decisions by taking actions in an environment to maximize cumulative reward.

2.2 Common Algorithms

Algorithm	Description	Use Case
Linear Regression	A statistical method for modeling the relationship between a dependent variable and one or more independent variables.	Predicting sales based on advertising spend.
Decision Trees	A flowchart-like tree structure where each internal node represents a feature, each branch represents a decision rule, and each leaf node represents an outcome.	Customer segmentation.
Support Vector Machines	A supervised learning model that analyzes data for classification and regression analysis.	Image classification.
Neural Networks	A series of algorithms that attempt to recognize underlying relationships in a set of data through a process that mimics the way the human brain operates.	Natural language processing.

3. Applications of Business Analytics and Machine Learning

The integration of business analytics and machine learning has led to numerous applications across various industries. Below are some prominent use cases:
