Density estimation #7

This method worked really well on my data! Is it possible to perform density estimation with ForestDiffusion?

Hi Calvin,

Our method does not perform density estimation. It could be possible to implement it following the approach used in the zero-shot classification, but it would be computationally intensive (n_t=10, n_z=10, 250 values = 250 x 10 x 10 xgboost predictions) and I'm not sure what would be the advantage over using standard kernel-based density estimation.

Hi Alexia, thanks -- makes sense!
