Introduction to Machine Learning
Machine learning (ML), a subset of artificial intelligence (AI), empowers systems to learn from data, identify patterns, and make decisions with minimal human intervention. Unlike traditional programming, where rules are explicitly coded, ML algorithms iteratively improve their performance by processing vast amounts of data. This paradigm shift has transformed industries ranging from healthcare to finance, making ML one of the most disruptive technologies of the 21st century
1.1Why Machine Learning Matters
.Automation: Reduces manual effort in tasks like data analysis and decision-making
.Personalization: Powers recommendation systems (e.g., Netflix, Amazon)
.Predictive Analytics: Enables forecasting in domains like weather, stock markets, and disease outbreaks
.Scalability: Processes large datasets far beyond human capability
