Model Architecture Inspection And Feature Extraction From Intermediate Layers

Hugging Face's model library — thousands of pretrained transformers for NLP, vision, audio.

Unique: Provides model.config to inspect architecture and supports registering forward hooks to extract intermediate outputs without modifying model code. Enables feature extraction by accessing hidden_states in model output without explicit hook registration.

vs others: More convenient than manual forward hook registration because hidden states are returned by default in model output. More flexible than task-specific feature extractors because it works with any model architecture.
