the LGBM looks great, and that optuna certainly seems like a clean way for model optimization i'll have to learn about that library. currently the only deployed model is the multi_model, and for it to deploy we have defined a wrapper around the model could you make something similar? |

There was a problem hiding this comment.
can you also add some metrics for the refit_best model

Sounds good, I'll run some similar experiments on the multi_model and update the PR once done. |

Introduced similar changes to the multimodel. I tried to make it so the deployment pipeline would need minimal changes. Let me know if anything here would break the larger deployment pipeline. @extreme4all |

This PR adds LightGBM + optuna optimization. It begins with an initial hyperparameter guess from long previous experiments, and does ten 5-fold stratified cross-validation experiments to do a short exploration of other hyperparameter sets. It still saves metrics and the final model artifact using mlflow.
