Perception and generation problems with lots of examples: images, speech, language, recommendation ranking. LLMs and diffusion models are deep learning systems.

#When to use

Perception and generation problems with lots of examples: images, speech, language, recommendation ranking. LLMs and diffusion models are deep learning systems.

#When not to

Tiny tabular datasets where a simple model (or rules) already works and you need easy explanations. Deep nets need data, compute, and careful evals.

#Quality checklist

  • Train/validation/test splits that match real use
  • Baseline simpler models before going deep
  • Monitor overfitting and distribution shift
  • Document data provenance and failure cases

#Example

Task: classify support tickets into 8 topics.
Start: bag-of-words logistic regression baseline.
Only move to a fine-tuned encoder if F1 gains justify the ops cost.
