பயிற்சி (training) மற்றும் அனுமான (inference) இடையே உள்ள வேறுபாடு என்ன?

TRAINING → teaching the model (the LEARNING phase):
  → feed lots of DATA → the model adjusts its parameters to learn patterns
  → computationally EXPENSIVE (lots of data, compute, time — e.g. training an LLM costs
    huge resources); done once (or periodically to update)
  → produces a trained MODEL
INFERENCE → using the trained model (the PREDICTION phase):
  → give the trained model NEW input → it produces an output (prediction/generation)
  → much CHEAPER/faster than training (a single forward pass); done MANY times (every
    time you use the model)
→ train once (expensive), infer many times (cheaper, in production)
