Here are three collabs that emphasize some simple concepts in ML.
Roscoff
GPR
1D GP process from the scratch. With no import something GPRoscoff01
Surrogate models for local energy in W and vibrational entropy for point defects in Fe GPRoscoff02
GNN
GCN from the scratch using just JAX (inspired from Prof. Jure Leskovec) GCNRoscoff03
