I’m really excited to share my latest blog post where I walkthrough how to use Gradient Boosting to fit entire Parameter Vectors, not just a single target prediction.

I’ve always wanted to explore the idea that boosted trees could fit entire coefficients of parameters of a distribution instead of only being able to predict a single value per leaf node. Well using {Jax} I was able to fit a Gradient Boosting Spline model where the model learns to predict the spline coefficients that best fit each individual observation. I think this has an implications for a lot of the advanced modeling techniques available to us; survival mode
