1. What is Machine Learning?

Machine learning involves the use of statistical techniques to enable computers to improve their performance on a specific task through experience. It allows systems to learn from data patterns without explicit programming. The primary goal of machine learning is to develop algorithms that can analyze data, learn from it, and make predictions or decisions based on that data.

2. Types of Machine Learning

Machine learning can be broadly categorized into three types:

3. Applications in Business

Machine learning has numerous applications in business analytics, enhancing decision-making processes and operational efficiency. Some key applications include:

• Predictive Analytics: Using historical data to forecast future trends and behaviors.
• Customer Segmentation: Grouping customers based on purchasing behavior to tailor marketing strategies.
• Fraud Detection: Identifying unusual patterns that may indicate fraudulent activity.
• Recommendation Systems: Providing personalized product recommendations based on user behavior.
• Supply Chain Optimization: Analyzing data to improve logistics and inventory management.
