# rrivera1849/LUAR-MUD
Author Style Representations using [LUAR](https://aclanthology.org/2021.emnlp-main.70.pdf).
The LUAR training and evaluation repository can be found [here](https://github.com/llnl/luar).
This model was trained on the Reddit Million User Dataset (MUD) found [here](https://aclanthology.org/2021.naacl-main.415.pdf).
## Usage
```python
from transformers import AutoModel, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("rrivera1849/LUAR-MUD")
model = AutoModel.from_pretrained("rrivera1849/LUAR-MUD")
# we embed `episodes`, a colletion of documents presumed to come from an author
# NOTE: make sure that `episode_length` consistent across `episode`
batch_size = 3
episode_length = 16
text = [
["Foo"] * episode_length,
["Bar"] * episode_length,
["Zoo"] * episode_length,
]
text = [j for i in text for j in i]
tokenized_text = tokenizer(
text,
max_length=32,
padding="max_length",
truncation=True,
return_tensors="pt"
)
# inputs size: (batch_size, episode_length, max_token_length)
tokenized_text["input_ids"] = tokenized_text["input_ids"].reshape(batch_size, episode_length, -1)
tokenized_text["attention_mask"] = tokenized_text["attention_mask"].reshape(batch_size, episode_length, -1)
print(tokenized_text["input_ids"].size()) # torch.Size([3, 16, 32])
print(tokenized_text["attention_mask"].size()) # torch.Size([3, 16, 32])
out = model(**tokenized_text)
print(out.size()) # torch.Size([3, 512])
# to get the Transformer attentions:
out, attentions = model(**tokenized_text, output_attentions=True)
print(attentions[0].size()) # torch.Size([48, 12, 32, 32])
