AdamW is a variant of the Adam
optimizer that separates weight decay from the gradient update based on the observation that the weight decay formulation is different when applied to SGD
and Adam
.
bitsandbytes also supports paged optimizers which take advantage of CUDAs unified memory to transfer memory from the GPU to the CPU when GPU memory is exhausted.
