## Model Description |
|
|
|
Graphix-T5 is a graph-aware semi-pretrained text-to-text PLM specifically designed to improve multi-hop reasoning for the complex text-to-SQL task. |
|
This novel architecture enhances the structural encoding capabilities of the T5 model while preserving its powerful contextual encoding ability. |
|
The experimental results demonstrate the effectiveness of GRAPHIX-T5 and underscore the importance of incorporating structural information in text-to-text PLMs for tackling intricate text-to-SQL challenges. |
|
The smaller gap in performance between the dev and test sets indicates the stronger generalization capability of Graphix-T5. |
|
|
|
## Training Data |
|
Graphix-3B is trained based on SPIDER, a cross-domain text-to-SQL benchmark. And it's evaluated in vanilla SPIDER dev, test, and other variants: SPIDER-SYN, SPIDER-DK, |
|
SPIDER-REALISTIC **without additional training**. This model will continue to be fine-tuned on more complex text-to-SQL data, |
|
i.e. BIRD to deal with harder but more real applications |
|
|
|
## To Begin With |
|
|
|
You can use this model directly with a pipeline for text generation. This example generates a different sequence each time it's run: |
|
```py |
|
from transformers import AutoTokenizer, AutoModel |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("patrickNLP/Graphix-3B") |
|
|
|
model = AutoModel.from_pretrained("patrickNLP/Graphix-3B") |
|
``` |
|
|
|
## Performance |
|
Graphix-3B w/ Picard maintains state-of-the-art (SOTA) semantic parsing capabilities, as demonstrated by its performance on the [`SPIDER`](https://yale-lily.github.io/spider) leaderboard. Its only submission achieves **74.0%** on EM and **77.6%** on EX in the testing dataset. |
|
