Model Training
The process of adjusting model parameters using data and an objective function.
Motivation
Model training solves the problem of fitting model parameters so predictions improve on examples.
Where it fits
It belongs to machine learning engineering.
Mental model
Training is an optimization loop: predict, measure error, update parameters, repeat.
Important details
Training depends on data, loss functions, optimization algorithms, compute, and evaluation strategy.
Common mistakes
- Mistaking low training error for real-world performance.
- Ignoring reproducibility.
