# ReasTAP

ReasTAP is a table reasoning model proposed in the EMNLP 2022 paper [ReasTAP: Injecting Table Reasoning Skills During Pre-training via Synthetic Reasoning Examples](https://arxiv.org/pdf/2210.12374.pdf). The original Github repository is [https://github.com/Yale-LILY/ReasTAP](https://github.com/Yale-LILY/ReasTAP).

## Description

`Yale-LILY/reastap-large-finetuned-logicnlg` is initialized with `Yale-LILY/reastap-large` and finetuned on [LogicNLG](https://arxiv.org/pdf/2004.10404.pdf).

## Usage

```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
import pandas as pd

tokenizer = AutoTokenizer.from_pretrained("Yale-LILY/reastap-large-finetuned-logicnlg")
model = AutoModelForSeq2SeqLM.from_pretrained("Yale-LILY/reastap-large-finetuned-logicnlg")

data = {
    "year": [1896, 1900, 1904, 2004, 2008, 2012],
    "city": ["athens", "paris", "st. louis", "athens", "beijing", "london"]
}
table = pd.DataFrame.from_dict(data)

title = "Olympic Games"
encoding = tokenizer(table=table, query=title, return_tensors="pt")

outputs = model.generate(**encoding)

print(tokenizer.batch_decode(outputs, skip_special_tokens=True))
# the olympic game were held in athens 2 time, in 1896 and 2004'
```

    abstract = "Reasoning over tabular data requires both table structure understanding and a broad set of table reasoning skills. Current models with table-specific architectures and pre-training methods perform well on understanding table structures, but they still struggle with tasks that require various table reasoning skills. In this work, we develop ReasTAP to show that high-level table reasoning skills can be injected into models during pre-training without a complex table-specific architecture design. We define 7 table reasoning skills, such as numerical operation, temporal comparison, and conjunction. Each reasoning skill is associated with one example generator, which synthesizes questions over semi-structured tables according to the sampled templates. We model the table pre-training task as a sequence generation task and pre-train ReasTAP to generate precise answers of the synthetic examples. ReasTAP is evaluated on four benchmarks covering three downstream tasks including 1) WikiSQL-Weak and WikiTQ for Table Question Answering, 2) TabFact for Table Fact Verification, and 3) LogicNLG for Faithful Table-to-Text Generation. Experimental results demonstrate that ReasTAP achieves new state-of-the-art results on all of them and delivers a significant improvement under low-resource setting.
