### `run_semeval.py`: relationship classification using R-Bert
R-BERT is a relationship classification head for BERT and RoBERTa, described [here](https://arxiv.org/pdf/1905.08284.pdf").
This example code fine-tunes R-BERT on the semeval 2010 Task 8 dataset:
```bash
python ./examples/run_semeval.py \
--data_dir $SEMEVAL_DIR \
--output_dir $RESULTS_DIR \
--model_name_or_path bert-base-uncased \
--do_train \
--do_eval \
--overwrite_output_dir \
--num_train_epochs 8.0 \
--per_gpu_train_batch_size 16 \
--per_gpu_eval_batch_size 16 \
--learning_rate 2e-5 \
--max_seq_length 128 \
--task_name semeval2010_task8 \
--train_on_other_labels \
--eval_on_other_labels \
--include_directionality
```
The ```$SEMEVAL_DIR``` should point to the extracted archive.
The ```--include_directionality``` flag trains a classifier using all 18 semeval classes. The
```--train_on_other_labels``` and ```--eval_on_other_labels``` flags also include instances labeled as 'Other' in the
training and evaluation respectively. Include all of these to be able to use the official evaluation script.
Note, although an F1 score is calculated in the python code, two additional files are also written out at the checkpoint
intervals ```{global_step}_semeval_results.tsv``` that may be used with the official Semeval evaluation script
(supplied in the semeval data archive). The dataset is available under Creative Commons Atrribution 3.0
Unported Licence (http://creativecommons.org/licenses/by/3.0/) and is available
[here](http://docs.google.com/leaf?id=0B_jQiLugGTAkMDQ5ZjZiMTUtMzQ1Yy00YWNmLWJlZDYtOWY1ZDMwY2U4YjFk&sort=name&layout=list&num=50).
for example:
```bash
./semeval2010_task8_scorer-v1.2.pl $SEMEVAL_DIR/{global_step}_semeval_results.tsv $SEMEVAL_DIR/TEST_FILE_SEMEVAL_SCRIPT_FORMAT.tsv
```
Using the ```bert-base-uncased``` should give around 87.6 undirected F1 (excluding other), with the official script.
However, the RoBERTa model can also be used with this head:
```bash
python ./examples/run_semeval.py \
--data_dir $SEMEVAL_DIR \
--output_dir $RESULTS_DIR \
--model_name_or_path roberta-large \
--model_type roberta \
--do_train \
--do_eval \
--overwrite_output_dir \
--num_train_epochs 8.0 \
--per_gpu_train_batch_size 16 \
--per_gpu_eval_batch_size 16 \
--learning_rate 2e-5 \
--max_seq_length 128 \
--task_name semeval2010_task8 \
--train_on_other_labels \
--eval_on_other_labels \
--include_directionality
```
This should give an undirected F1 of aroubd 90.8 (excluding other) with the official script.

## How to use DistilBERT
Transformers includes five pre-trained Distil* models, currently only provided for English and German (we are investigating the possibility to train and release a multilingual version of DistilBERT):
Transformers includes two pre-trained Distil* models, currently only provided for English (we are investigating the possibility to train and release a multilingual version of DistilBERT):
- `distilbert-base-uncased`: DistilBERT English language model pretrained on the same data used to pretrain Bert (concatenation of the Toronto Book Corpus and full English Wikipedia) using distillation with the supervision of the `bert-base-uncased` version of Bert. The model has 6 layers, 768 dimension and 12 heads, totalizing 66M parameters.
- `distilbert-base-uncased-distilled-squad`: A finetuned version of `distilbert-base-uncased` finetuned using (a second step of) knwoledge distillation on SQuAD 1.0. This model reaches a F1 score of 86.9 on the dev set (for comparison, Bert `bert-base-uncased` version reaches a 88.5 F1 score).
- `distilbert-base-german-cased`: DistilBERT German language model pretrained on 1/2 of the data used to pretrain Bert using distillation with the supervision of the `bert-base-german-dbmdz-cased` version of German DBMDZ Bert. For NER tasks the model reaches a F1 score of 83.49 on the CoNLL-2003 test set (for comparison, `bert-base-german-dbmdz-cased` reaches a 84.52 F1 score), and a F1 score of 85.23 on the GermEval 2014 test set (`bert-base-german-dbmdz-cased` reaches a 86.89 F1 score).
- `distilgpt2`: DistilGPT2 English language model pretrained with the supervision of `gpt2` (the smallest version of GPT2) on [OpenWebTextCorpus](https://skylion007.github.io/OpenWebTextCorpus/), a reproduction of OpenAI's WebText dataset. The model has 6 layers, 768 dimension and 12 heads, totalizing 82M parameters (compared to 124M parameters for GPT2). On average, DistilGPT2 is two times faster than GPT2.
- `distilroberta-base`: DistilRoBERTa English language model pretrained with the supervision of `roberta-base` solely on [OpenWebTextCorpus](https://skylion007.github.io/OpenWebTextCorpus/), a reproduction of OpenAI's WebText dataset (it is ~4 times less training data than the teacher RoBERTa). The model has 6 layers, 768 dimension and 12 heads, totalizing 82M parameters (compared to 125M parameters for RoBERTa-base). On average DistilRoBERTa is twice as fast as Roberta-base.

# PPLM
This folder contains the original code used to run the Plug and Play Language Model (PPLM).
![header image](./imgs/headfigure.png)
## Plug and Play Language Models: a Simple Approach to Steerable Text Generation
Authors: [Sumanth Dathathri](https://dathath.github.io/), Andrea Madotto, Janice Lan, Jane Hung, Eric Frank, [Piero Molino](https://w4nderlu.st/), [Jason Yosinski](http://yosinski.com/), and [Rosanne Liu](http://www.rosanneliu.com/)
PPLM allows a user to flexibly plug in one or more tiny attribute models representing the desired steering objective into a large, unconditional LM. The method has the key property that it uses the LM _as is_---no training or fine-tuning is required---which enables researchers to leverage best-in-class LMs even if they do not have the extensive hardware required to train them.
Paper link:
Blog link: https://eng.uber.com/pplm
## Setup
```bash
git clone https://github.com/huggingface/transformers && cd transformers
pip install [--editable] .
pip install nltk torchtext # additional requirements.
cd examples/pplm
```
## PPLM-BoW
### Example command for bag-of-words control
```bash
python run_pplm.py -B space --cond_text "The president" --length 100 --gamma 1.5 --num_iterations 3 --num_samples 1 --stepsize 0.01 --window_length 5 --kl_scale 0.01 --gm_scale 0.95
```
### Tuning hyperparameters for bag-of-words control
1. Increase `--stepsize` to intensify topic control, and decrease its value to soften the control. `--stepsize 0` recovers the original uncontrolled GPT-2 model.
2. If the language being generated is repetitive (For e.g. "science science experiment experiment"), there are several options to consider: </br>
a) Reduce the `--stepsize` </br>
b) Increase `--kl_scale` (the KL-loss coefficient) or decrease `--gm_scale` (the gm-scaling term) </br>
c) Add `--grad-length xx` where xx is an (integer <= length, e.g. `--grad-length 30`).</br>
## PPLM-Discrim
### Example command for discriminator based sentiment control
```bash
python run_pplm.py -D sentiment --class_label 3 --cond_text "The lake" --length 10 --gamma 1.0 --num_iterations 10 --num_samples 1 --stepsize 0.03 --kl_scale 0.01 --gm_scale 0.95
```
### Tuning hyperparameters for discriminator control
1. Increase `--stepsize` to intensify topic control, and decrease its value to soften the control. `--stepsize 0` recovers the original uncontrolled GPT-2 model.
2. Use `--class_label 3` for negative, and `--class_label 2` for positive
### Example command for detoxificiation:
```bash
python run_pplm.py -D toxicity --length 100 --num_iterations 10 --cond-text 'TH PEOPLEMan goddreams Blacks' --gamma 1.0 --num_samples 10 --stepsize 0.02

Segment token indices to indicate first and second portions of the inputs.
Indices are selected in ``[0, 1]``: ``0`` corresponds to a `sentence A` token, ``1``
**attention_mask**: (`optional`) ``torch.FloatTensor`` of shape ``(batch_size, sequence_length)``:
Mask to avoid performing attention on padding token indices.

Mask to nullify selected heads of the self-attention modules.
Mask values selected in ``[0, 1]``:
``1`` indicates the head is **not masked**, ``0`` indicates the head is **masked**.
**inputs_embeds**: (`optional`) ``torch.FloatTensor`` of shape ``(batch_size, sequence_length, embedding_dim)``:
Optionally, instead of passing ``input_ids`` you can choose to directly pass an embedded representation.
This is useful if you want more control over how to convert `input_ids` indices into associated vectors
than the model's internal embedding lookup matrix.

''' Script for downloading all GLUE data.
Original source: https://gist.github.com/W4ngatang/60c2bdb54d156a41194446737ce03e2e
Note: for legal reasons, we are unable to host MRPC.
You can either use the version hosted by the SentEval team, which is already tokenized,
or you can download the original data from (https://download.microsoft.com/download/D/4/6/D46FF87A-F6B9-4252-AA8B-3604ED519838/MSRParaphraseCorpus.msi) and extract the data from it manually.
For Windows users, you can run the .msi file. For Mac and Linux users, consider an external library such as 'cabextract' (see below for an example).
You should then rename and place specific files in a folder (see below for an example).
mkdir MRPC
cabextract MSRParaphraseCorpus.msi -d MRPC
cat MRPC/_2DEC3DBE877E4DB192D17C0256E90F1D | tr -d $'\r' > MRPC/msr_paraphrase_train.txt
cat MRPC/_D7B391F9EAFF4B1B8BCE8F21B20B1B61 | tr -d $'\r' > MRPC/msr_paraphrase_test.txt
rm MRPC/_*
rm MSRParaphraseCorpus.msi
1/30/19: It looks like SentEval is no longer hosting their extracted and tokenized MRPC data, so you'll need to download the data from the original source for now.
2/11/19: It looks like SentEval actually *is* hosting the extracted data. Hooray!
