## parkervg/destt5-text2sql

Fine-tuned weights for the text2sql model described in [Correcting Semantic Parses with Natural Language through Dynamic
Schema Encoding](https://arxiv.org/pdf/2305.19974.pdf), based on [t5-base](https://huggingface.co/t5-base).


### Training Data

The model has been fine-tuned on the 7,481 training examples in the [SPLASH interactive semantic parsing dataset](https://github.com/MSR-LIT/Splash).

Rather than seeing the full database schema, it only received the filtered schema as predicted by the [destt5-schema-prediction model](https://huggingface.co/parkervg/destt5-schema-prediction)


### Training Objective

This model was initialized with [t5-base](https://huggingface.co/t5-base) and fine-tuned with the text-to-text generation objective.

As this model works in the interactive setting, we utilize the standard text2sql features such as `question` and `db_schema`, in addition to `feedback` and `incorrect_parse`.

Importantly, the `[table]`, `[column]`, `[content]` features are expected to be the 'gold' schema items, as predicted by an initial auxiliary schema prediction model.

```
[question] || [incorrect_parse] || [db_id] | [table] : [column] ( [content] , [content] ) , [column] ( ... ) , [...] | [table] : ... | ... || [feedback]
```

The model then attempts to parse the corrected SQL query, using the filtered database schema items. This is prefaced by the `db_id`.

```
[db_id] | [sql]
```


### Performance

When this model receives the serialized database schema as predicted by [destt5-schema-prediction](https://huggingface.co/parkervg/destt5-schema-prediction), it achieves 53.43% correction accuracy (exact-match) on the SPLASH test set.
