Validation ### Key Metrics * **Training vs. Validation Loss**: Ensure the model is learning without over-fitting. * **Accuracy Improvement**: Verify the model correctly predicts outputs in your validation set compared to the base model. * **Regression Check**: Run your **Test Set** against the new weights to ensure general performance remains high and no regressions were introduced. ## Next * Deploy a successful run: [Deployment](/build/models/deployment) * Benchmark the candidate model on golden cases: [Test Sets](/test/test_sets/creation)
