Frequently Asked Questions
Start with: Python, Pandas for data manipulation, scikit-learn for classical ML, and basic statistics. For deep learning projects: add PyTorch or TensorFlow. For NLP: learn transformers and the Hugging Face library. Most business ML projects use classical ML (random forests, gradient boosting) rather than deep learning.
It depends on complexity. Simple classification: 500-5,000 labelled examples. Recommendation engines: 10,000+ user interactions. NLP tasks: 10,000+ text examples (or use pre-trained models with fewer). Computer vision: 1,000+ images per class (with transfer learning). More data generally means better models, but diminishing returns set in.
