### Saved Pseudo-Labels
These are the generations of various large models on various large **training** sets. All in all they took about 200 GPU hours to produce.
### Available Pseudo-labels
| Dataset | Model | Link | Rouge Scores | Notes
|---------|-----------------------------|----------------------------------------------------------------------------------------|--------------------|-------------------------------------------------------------------------------------------------------------
| XSUM | `facebook/bart-large-xsum` | [download](https://cdn-datasets.huggingface.co/pseudo/xsum/bart_xsum_pl.tgz) | 49.8/28.0/42.5 |
| XSUM | `google/pegasus-xsum` | [download](https://cdn-datasets.huggingface.co/pseudo/xsum/pegasus_xsum.tgz) | 53.3/32.7/46.5 |
| XSUM | `facebook/bart-large-xsum` | [download](https://cdn-datasets.huggingface.co/pseudo/xsum/xsum_pl2_bart.tgz) | | Bart pseudolabels filtered to those with Rouge2 > 10.0 w GT.
| CNN/DM | `sshleifer/pegasus-cnn-ft-v2` | [download](https://cdn-datasets.huggingface.co/pseudo/cnn_dm/pegasus_cnn_cnn_pls.tgz) | 47.316/26.65/44.56 | do not worry about the fact that train.source is one line shorter.
| CNN/DM | `facebook/bart-large-cnn` | [download](https://cdn-datasets.huggingface.co/pseudo/cnn_dm/cnn_bart_pl.tgz) | | 5K (2%) are missing, there should be 282173
| CNN/DM | `google/pegasus-xsum` | [download](https://cdn-datasets.huggingface.co/pseudo/cnn_dm/pegasus_xsum_on_cnn.tgz) | 21.5/6.76/25 | extra labels for xsum distillation Used max_source_length=512, (and all other pegasus-xsum configuration).
| EN-RO | `Helsinki-NLP/opus-mt-en-ro` | [download](https://cdn-datasets.huggingface.co/pseudo/wmt_en_ro/opus_mt_en_ro.tgz) | |
| EN-RO | `facebook/mbart-large-en-ro` | [download](https://cdn-datasets.huggingface.co/pseudo/wmt_en_ro/mbart_large_en_ro.tgz) | |
(EN_RO = WMT 2016 English-Romanian).
Example Download Command:
```bash
curl -S https://cdn-datasets.huggingface.co/pseudo/xsum/bart_xsum_pl.tgz | tar -xvz -C .
```
### Generating New Pseudolabels
Here is the command I used to generate the pseudolabels in the second row of the table, after downloading XSUM from [here](https://cdn-datasets.huggingface.co/summarization/xsum.tar.gz).
```bash
python -m torch.distributed.launch --nproc_per_node=8 run_distributed_eval.py \
--model_name google/pegasus-xsum \
--save_dir pegasus_xsum \
--data_dir xsum \
--bs 8 --sync_timeout 60000 \
--max_source_length 512 \
--type_path train
```
+ These commands takes a while to run. For example, `pegasus_cnn_cnn_pls.tgz` took 8 hours on 8 GPUs.
+ Pegasus does not work in fp16 :(, Bart, mBART and Marian do.
+ Even if you have 1 GPU, `run_distributed_eval.py` is 10-20% faster than `run_eval.py` because it uses `SortishSampler` to minimize padding computation.
### Contributions
Feel free to contribute your own pseudolabels via PR. Add a row to this table with a new google drive link (or other command line downloadable link).
