mega-small-2048 on simple wikipedia
MEGA for masked LM 'small' (12 layers, 512 hidden size, 2048 ctx in chunks of 1024) on the pszemraj/simple_wikipedia_LM dataset.
It achieves the following results on the evaluation set:
- Loss: 3.4773
- Accuracy: 0.4591
Model description
See config for architecture details. While not a ready 'pretrained' model, this was trained from scratch.
This model uses the tokenizer from roberta-base.
