Package builtin is Hermod's built-in ML engine: datasets, training, versions and predictions in Hermod's own process, in pure Go, with no hermod-ml worker to run.

learn
Package learn holds the built-in ML engine's algorithms, in pure Go: ridge and logistic regression, a random forest, gradient-boosted trees and a small multilayer perceptron, over the same preprocessing the hermod-ml worker applies (ml/worker/hermod_ml/training.py build_pipeline): a missing number gets the training median, numbers are standardised for the linear model and the network, and text is one-hot encoded.

table
Package table is the built-in ML engine's dataset in memory: typed columns, read from JSON rows, CSV or Excel, with the hermod-ml worker's typing rules (ml/worker/hermod_ml/datasets.py), so the same file gives the same columns on either engine.

Package inference calls a model server and turns its answer back into rows.

Package onnxscore evaluates small tabular ONNX models in pure Go: the linear models and tree ensembles scikit-learn and XGBoost export through skl2onnx and onnxmltools, with the preprocessing glue those exports carry.

Package recommend serves the recommendation models the hermod-ml worker trains (ml/worker/hermod_ml/recommend.py) in-process: it parses a version's artifact once and answers "which items next for this person" and "which items are like this one" from it, without a call to the worker.

Package worker is Hermod's client for its hermod-ml worker: the Python process that holds datasets, trains models on them, exports each one to ONNX and serves it over the Open Inference Protocol.
