Semantic Validation
The dataset for fine-tuning Phi-2 was constructed through a multi-stage process involving manual rewrites, LLM-based paraphrasing, and script-generated synthetic examples, followed by rigorous validation.

NL-SQL Pairs
The training dataset comprised approximately 2,500 natural language-SQL pairs, crucial for capturing the diversity of query structures and parameter variations within the SDSS domain.
LoRA for Parameter-Efficient Fine-tuning
Low-Rank Adaptation (LoRA) was used for fine-tuning, significantly reducing memory and computation requirements. This allowed the model to be trained efficiently on a small subset of pre-trained weights, making it feasible for deployment on resource-constrained systems. Key metrics: Rank (r)=8, Scaling Factor (α)=16, Dropout=0.05.
0%
Syntactic Accuracy
The fine-tuned Phi-2 model achieved a syntactic accuracy of approximately 94% on the validation set, ensuring that nearly all generated SQL queries were structurally valid and executable.
0%
Semantic Accuracy
Semantic accuracy ranged from 60-70%, indicating that the model largely captured the intent of natural language queries, despite occasional challenges with complex conditions or parameter ranges.
| Benefit | Description |
|---|---|
| Lower Barrier to Access | Enables non-experts and students to query complex databases without SQL proficiency. |
| Efficient Data Exploration | Streamlines target selection for proposals (JWST, ALMA, HST) and large-sample analyses. |
| Educational Tool | Promotes exploratory learning for new researchers and students. |
| Scalability | Foundation for future interfaces for LSST, DESI, SKA, handling petabyte-scale archives. |
