oBERT-12-downstream-dense-squadv1

This model is obtained with The Optimal BERT Surgeon: Scalable and Accurate Second-Order Pruning for Large Language Models.

It corresponds to the model presented in the Table 3 - 12 Layers - 0% Sparsity, and it represents an upper bound for performance of the corresponding pruned models:

• 80% unstructured: neuralmagic/oBERT-12-downstream-pruned-unstructured-80-squadv1
• 80% block-4: neuralmagic/oBERT-12-downstream-pruned-block4-80-squadv1
• 90% unstructured: neuralmagic/oBERT-12-downstream-pruned-unstructured-90-squadv1
• 90% block-4: neuralmagic/oBERT-12-downstream-pruned-block4-90-squadv1

SQuADv1 dev-set:

EM = 82.71
F1 = 89.48
