Pipeline with cross validation
WebbMetrics computed during cross validation are based on all folds and therefore all samples from the training set. Learn more about metrics in automated machine learning. When either a custom validation set or an automatically selected validation set is used, model evaluation metrics are computed from only that validation set, not the training data. WebbClearly the ML pipeline approach of feature engineering → gbdt with careful target engineering and cross validation has been very successful in medium horizon investing. …

When a new repository is made, we would ideally also have the pipeline present by default (including triggering it via the Build Validation).
