Welcome to our comprehensive guide on using the Mistral-7B model for query generation! This sophisticated model has been fine-tuned specifically for creating synthetic queries to enhance your embedding fine-tuning tasks.

What is Nixie Query Generation?

Nixie Query Generation is a beneficial technique that lets you generate synthetic queries based on existing document-query pairs. Imagine trying to churn out creative titles for your book based solely on a few chapters. That’s how the model operates—it takes limited input (your queries) and expands on it to generate a wider range of applicable queries. This is particularly valuable in information retrieval where finding the right match is paramount.

Main Use Cases

• Synthetic query generation for downstream embedding fine-tuning tasks
• Synthetic dataset expansion for further embedding training

Training Data

The model uses 200k query-document pairs sampled from a diverse set of information retrieval datasets. This vast variety allows for effective training and robust output.

Model Variants

The repository comprises several versions of the model for different use cases:

• model-*.safetensors: PyTorch FP16 checkpoint, ideal for downstream fine-tuning
• ggml-model-f16.gguf: Non-quantized GGUF F16 checkpoint for CPU inference
• ggml-model-q4.gguf: Quantized GGUF Q4_0 checkpoint for faster CPU inference

Prompt Formats

When interacting with the model, be sure to structure your prompts correctly. Here’s how:

The prompt format is:

document next [shortmediumlong]? [questionregular]? query:

Remember, the suffix query: has no trailing space, so double-check your formatting!

Inference Example

To run inference on your model using the Llama-CPP interface, here’s a command to help you:

bash $ .main -m ~models/nixie-querygen-v2/ggml-model-q4.gguf -p "git lfs track will begin tracking a new file or an existing file..."

A few parameters you can customize include sampling rates and repeat penalties, allowing you to adjust how the model generates outputs to your liking.

Training Configuration

Training the model requires a specific configuration file that outlines various parameters, such as:

 
train_dataset: home/shuttydata/nixiesearch-datasets/query-docdata/train,
eval_dataset: home/shuttydata/nixiesearch-datasets/query-docdata/test,
seq_len: 512,
num_train_epochs: 1,
per_device_train_batch_size: 6,
...

Feel free to adjust these settings depending on your device capabilities and project needs!

Troubleshooting

If you encounter any issues while using the model, consider the following:

• Ensure your environment meets all prerequisites for running the required libraries.
• Double-check your prompt formatting to avoid syntax errors.
• If you experience slow performance, try quantized models that are optimized for CPU inference.
• For any specific error messages, consult the documentation of the respective libraries used.
