MiniLM: Small and Fast Pre-trained Models for Language Understanding and Generation
MiniLM is a distilled model from the paper "MiniLM: Deep Self-Attention Distillation for Task-Agnostic Compression of Pre-Trained Transformers".
Please find the information about preprocessing, training and full details of the MiniLM in the original MiniLM repository.
Please note: This checkpoint can be an inplace substitution for BERT and it needs to be fine-tuned before use!
English Pre-trained Models
We release the uncased 12-layer model with 384 hidden size distilled from an in-house pre-trained UniLM v2 model in BERT-Base size.
- MiniLMv1-L12-H384-uncased: 12-layer, 384-hidden, 12-heads, 33M parameters, 2.7x faster than BERT-Base
Fine-tuning on NLU tasks
We present the dev results on SQuAD 2.0 and several GLUE benchmark tasks.
| Model | #Param | SQuAD 2.0 | MNLI-m | SST-2 | QNLI | CoLA | RTE | MRPC | QQP |
|---|---|---|---|---|---|---|---|---|---|
| BERT-Base | 109M | 76.8 | 84.5 | 93.2 | 91.7 | 58.9 | 68.6 | 87.3 | 91.3 |
| MiniLM-L12xH384 | 33M | 81.7 | 85.7 | 93.0 | 91.5 | 58.5 | 73.3 | 89.5 | 91.3 |
