What Is Machine Learning
Simple definition:
- Machine Learning (ML) enables systems to learn from data and improve over time without explicit programming, making predictions and decisions based on patterns in the data.
Difference from traditional programming:
- Traditional Programming: Developers write explicit rules and logic for systems to follow.
- Machine Learning: Systems learn from data, improving predictions and decisions as they receive more data, without needing programmed rules for each scenario.
Basic machine learning workflow (visual):
- Data Input: ML starts with data (e.g., sales or customer behavior data).
- Pattern Learning: ML algorithms analyze data to identify relationships and patterns.
- Prediction/Decision: The model makes predictions or decisions based on learned patterns (e.g., email classification or product recommendations).
