Training bir ML modelini verilerden öğretme işlemidir (desenleri öğrenme, parametreleri ayarlama), inference ise eğitilmiş modeli yeni veriler üzerinde tahminler yapmak için kullanmaktır. Bunlar farklı özelliklere ve maliyetlere sahip olan ayrı aşamalardır.
Training ve inference karşılaştırması
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)
