AMOS
This repository contains the scripts for fine-tuning AMOS pretrained models on GLUE and SQuAD 2.0 benchmarks.
Paper: Pretraining Text Encoders with Adversarial Mixture of Training Signal Generators
Overview
We provide the scripts in two versions, based on two widely-used open-source codebases, the Fairseq Library and the Huggingface Transformers Library. The two code versions are mostly equivalent in functionality, and you are free to use either of them. However, we note that the fairseq version is what we used in our experiments, and it will best reproduce the results in the paper; the huggingface version is implemented later to provide compatibility with the Huggingface Transformers Library, and may yield slightly different results.
Please follow the README files under the two directories for running the code.
GLUE Fine-Tuning Results
The General Language Understanding Evaluation (GLUE) benchmark is a collection of sentence- or sentence-pair language understanding tasks for evaluating and analyzing natural language understanding systems.
GLUE dev set results of AMOS base++ model are as follows (median of 5 different random seeds):
| Model | MNLI-m/mm | QQP | QNLI | SST-2 | CoLA | RTE | MRPC | STS-B | AVG |
|---|---|---|---|---|---|---|---|---|---|
| AMOS base++ | 90.5/90.4 | 92.4 | 94.4 | 95.5 | 71.8 | 86.6 | 91.7 | 92.0 | 89.4 |
GLUE test set results of AMOS base++ model are as follows (no ensemble, task-specific tricks, etc.):
| Model | MNLI-m/mm | QQP | QNLI | SST-2 | CoLA | RTE | MRPC | STS-B | AVG |
|---|---|---|---|---|---|---|---|---|---|
| AMOS base++ | 90.4/89.9 | 90.2 | 94.6 | 96.8 | 69.2 | 83.6 | 88.9 | 91.3 | 88.1 |
SQuAD 2.0 Fine-Tuning Results
Stanford Question Answering Dataset (SQuAD) is a reading comprehension dataset, consisting of questions posed by crowdworkers on a set of Wikipedia articles, where the answer to every question is a segment of text, or span, from the corresponding reading passage, or the question might be unanswerable.
SQuAD 2.0 dev set results of AMOS base++ and large++ models are as follows (median of 5 different random seeds):
| Model | EM | F1 |
|---|---|---|
| AMOS base++ | 85.0 | 87.9 |
