The choice of loss shapes learning; the metric used to judge the final workflow may be different. Labels can come from measurements, later results, or annotation. Examine disagreements and ambiguous cases rather than assume every recorded answer is right. If the label captures an old decision process, the model can reproduce that process's limitations. Split the data to match how the model will meet new cases. Random row splits can leak information when repeat records describe the same subject. Forecasts generally need time-respect evaluation. Fit preprocessing steps only on the training partition before applying them to validation and test examples. After training, inspect performance for relevant classes and operating conditions. Class imbalance can make overall accuracy misleading. Decide how uncertain or unfamiliar inputs should be handled, and maintain a route for correcting labels and reviewing systematic mistakes.
