Optimizing NLP Models through Quantization and Accelerated Training
In this project, I trained a text-to-SQL model using the Code-Gemma-7B model to facilitate SQL query generation from natural language inputs. The project involved several key steps and methodologies:
- Develop a robust text-to-SQL model: My goal was to generate accurate SQL queries based on user-provided English questions and a given database schema.
- Optimize training using LORA and quantization: I aimed to enhance model efficiency and performance while reducing computational resource requirements.
- Utilize Weights & Biases (W&B): I tracked and logged the model training processes and outcomes for transparency and reproducibility.
- Model Selection and Training
- Model: I selected Code-Gemma-7B, a large language model fine-tuned for text-to-SQL tasks.
- Optimization Techniques:
- LORA (Low-Rank Adaptation): I applied LORA to update only a small percentage (approximately 0.6%) of the model's parameters, significantly reducing training overhead.
- Quantization: This helped reduce the model size and memory usage without a substantial loss in performance.
- Training Process
- Environment: I utilized a Kaggle environment with limited GPU memory.
- Training Data: I employed a custom dataset for fine-tuning the model, containing various SQL schema definitions and corresponding queries.
- Epochs and Batch Size: I trained the model for 1 epoch due to memory constraints, experimenting with different batch sizes and sequence lengths to avoid out-of-memory errors.
- Logging and Monitoring
- Weights & Biases: I integrated W&B for real-time tracking and logging of training metrics such as loss, runtime, and parameter updates.
- Model Evaluation: I evaluated the model's performance on test datasets, comparing generated SQL queries with original ones.
- Model Deployment
- Model Saving and Uploading: I saved the trained model and uploaded it to the Hugging Face Hub for easy access and deployment.
- Inference Pipeline: I created a pipeline for generating SQL queries from natural language inputs using the fine-tuned model.
- Training Efficiency: The training process, optimized with LORA and quantization, took nearly 2 hours for 1 epoch on the available GPU.
- Model Performance: While the model generated decent results, there is room for improvement with further training and parameter tuning.
- Generated Queries: The model produced SQL queries that, although not perfect, were reasonably accurate and could be further refined.
- Extended Training: I plan to utilize more powerful GPUs (e.g., A100 on Google Colab) to increase the training data and epochs for better performance.
- Parameter Tuning: I will experiment with different LORA ranks, batch sizes, and sequence lengths to optimize model accuracy and efficiency.
- Model Evaluation and Testing: I will continue to evaluate the model on diverse datasets to ensure robustness and generalizability.
This project highlights the potential of large language models like Code-Gemma-7B for automating SQL query generation, offering significant time savings and accuracy improvements in database management and querying tasks.
