What Are Machine Learning Models?
Machine Learning models are algorithms that learn patterns from data and make predictions or decisions without being explicitly programmed. They enable systems to:
- Identify patterns from large datasets
- Adapt based on new input data
- Predict outcomes and optimize performance
These models form the foundation for AI applications in finance, healthcare, retail, manufacturing and beyond.
