Catastrophic forgetting test results:

Initial evaluation loss on 1k subset of HuggingFaceTB/cosmopedia-100k dataset was 1.217. 100 steps of LISA training reduced this to 1.153.

Comparison to control: cosmo-1b started out with 1.003 loss on (a different subset of) dataset, increasing to 1.024 at 100 steps.
