50. Tiny Text Classifier with a Transformer Intro in PyTorch
50.5 Practice, Tip and Close
Why. Close Phase 3 deep-learning drafts and point to classical NLP next.
How.
Chapter practice
- Add two new fictional reviews to the training list; retrain.
- Explain why padding_idx=0 matters.
- Write when you would graduate to a real TransformerEncoder or an LLM API (Gen AI).
Thodkyaat sangaycha tar (quick recap)
- Token ids + embeddings unlock text in PyTorch
- Mean-pool classifier is a gentle on-ramp
- Full transformers / ChatGPT-scale = later / Gen AI lane
- Phase 3 DL block (ch41–ch50) complete in draft
Samajla ka? Deep learning draft wave done. Coming next : Chapter 51 — What Is Natural Language Processing (classical NLP block).
