Direct Use
=============

It is possible to use this model to generate text, which is useful for experimentation and understanding its capabilities. **It should not be directly used for production or work that may directly impact people.**

How to Use
=============

You can very easily load the models with Transformers, instead of downloading them manually. The [T5-Large model](https://huggingface.co/t5-large) is the backbone of our model. Here is how to use the model in PyTorch:

```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
tokenizer = AutoTokenizer.from_pretrained("him1411/EDGAR-T5-Large")
model = AutoModelForSeq2SeqLM.from_pretrained("him1411/EDGAR-T5-Large")
```
Or just clone the model repo
```
git lfs install
git clone https://huggingface.co/him1411/EDGAR-T5-Large
```

Inference Example
=============

Here, we provide an example for the "ContextNER" task. Below is an example of one instance.

```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
tokenizer = AutoTokenizer.from_pretrained("him1411/EDGAR-T5-Large")
model = AutoModelForSeq2SeqLM.from_pretrained("him1411/EDGAR-T5-Large")
# Input shows how we have appended instruction from our file for HoC dataset with instance.
input = "14.5 years . The definite lived intangible assets related to the contracts and trade names had estimated weighted average useful lives of 5.9 years and 14.5 years, respectively, at acquisition."
tokenized_input= tokenizer(input)
# Ideal output for this input is 'Definite lived intangible assets weighted average remaining useful life'
output = model(tokenized_input)
```

## Results on Dowstream datasets
EDGAR-T5-Large was finetuned on some downstream datasets to get better results than T5 large. BloombergGPT 50B was used as baseline. 

| Dataset  | Bloomberg GPT 50B | T5 Large | Edgar T5 Large |
|----------|-------------------|----------|----------------|
| FiQA SA  | 75.07             | 74.89    | 80.42          |
| FPB      | 51.07             | 55.77    | 79.69          |
| Headline | 82.20             | 90.55    | 93.55          |
