Pocket Foundation Models: Distilling TFMs into CPU-Ready Gradient-Boosted Trees
A recent study introduces Pocket Foundation Models, which distill tabular foundation models (TFMs) into CPU-ready gradient-boosted trees, significantly reducing inference time from 151-1,275 ms on GPU to just 1.9 ms on CPU. This advancement utilizes stratified out-of-fold teacher labeling to address challenges in in-context learning, achieving a macro-mean AUC of 0.882 across 153 classification datasets.
