Feature engineering is the process of using domain knowledge to create, transform, or select input variables (features) that help ML models ...

Overfitting occurs when a model learns the training data too well (including noise), so it performs poorly on new data. **Signs:** High tra...

A Transformer uses **self-attention** to process all tokens in a sequence simultaneously (unlike RNNs which process sequentially). Key comp...

**Supervised learning** — model learns from labelled data (input → output pairs) - Examples: Linear regression, Random Forest, SVM - Use...

I want to start learning Machine Learning but have a limited budget. What are the best free courses, YouTube channels, and books to learn ML...
