Interview Questions

1. Why are these techniques important? — Production ML models need to be fast, small, and efficient. These techniques bridge the gap between research accuracy and production constraints.

2. When would you use model compression? — When deploying to resource-constrained environments (mobile, IoT), reducing inference costs, or meeting latency requirements.

3. What is the trade-off between model size and accuracy? — Compression techniques typically sacrifice some accuracy for significant gains in size and speed. The key is finding the right balance for your use case.

Summary

Advanced ML techniques enable deploying accurate models within real-world constraints. Knowledge distillation, quantization, pruning, and compression reduce model size and latency. NAS automates architecture design. Federated learning enables privacy-preserving training. Edge ML brings inference to devices.
