I’m trying to follow this example: Multi-output Gaussian Processes: Coregionalization models using Hamadard product — PyMC example gallery especially I’m interested in predicting the outcomes within temporal gaps for some groups assuming the outcomes for other groups are known.
Unfortunately the full GP implementation from that example is very slow for my dataset even on 4 Nvidia GPUs. (1000s of time points x 5 groups). I wonder if it is possible to use HSGP approximation to speed things up.
