1. What is Machine Learning and How Does it Differ from Traditional Programming?

Machine learning is a subset of artificial intelligence (AI) that empowers computers to learn from data without being explicitly programmed. Unlike traditional programming, where developers write specific instructions for every task, machine learning algorithms use data to identify patterns, make predictions, and improve their performance over time.

1.1 The Core Concept Explained

Machine learning allows computers to learn from data and make decisions with minimal human intervention. This is achieved through algorithms that can:

• Identify patterns: Uncover hidden relationships within datasets.
• Make predictions: Forecast future outcomes based on historical data.
• Improve performance: Continuously refine their accuracy as they are exposed to more data.

1.2 Traditional Programming vs. Machine Learning: A Comparative Analysis

The key difference lies in how tasks are approached:

Feature	Traditional Programming	Machine Learning
Approach	Explicitly programmed with step-by-step instructions	Learns from data to make predictions or decisions
Data Dependency	Less dependent on large datasets	Heavily relies on data to train and improve accuracy
Adaptability	Limited adaptability to new situations	Adapts to new data and improves performance over time
Problem Solving	Best for well-defined problems with clear rules	Excels in complex, data-rich environments with unclear rules
Human Intervention	Requires frequent human intervention for updates and fixes	Requires less human intervention after initial training

1.3 Historical Context and Evolution of Machine Learning

The concept of machine learning dates back to the mid-20th century with pioneers like Arthur Samuel, who coined the term and developed programs that could learn from experience. Over the decades, machine learning has evolved through several key phases:
