  • Stop Tuning Hyperparameters. Start Tuning Your Problem.

    Stop Tuning Hyperparameters. Start Tuning Your Problem. 80% of ML projects fail from bad problem framing, not bad models. A 5-step protocol to define the right problem before you write training code. The post Stop Tuning Hyperparameters. Start Tuning Your Problem. appeared first on Towards Data Science.

  • A Visual Guide to Tuning Gradient Boosted Trees

    A Visual Guide to Tuning Gradient Boosted Trees Introduction My previous posts looked at the bog-standard decision tree and the wonder of a random forest. Now, to complete the triplet, I’ll visually explore gradient boosted trees! There are a bunch of gradient boosted tree libraries, including XGBoost, CatBoost, and LightGBM. However, for this I’m going…

  • Exploring New Hyperparameter Dimensions with Laplace Approximated Bayesian Optimization

    Exploring New Hyperparameter Dimensions with Laplace Approximated Bayesian Optimization Is it better than grid search? Image by author from canva When I notice my model is overfitting, I often think, “It is time to regularize”. But how do I decide which regularization method to use (L1, L2) and what parameters to choose? Typically, I perform hyperparameter optimization…
