Summary
A local LLM is fine-tuned to categorize household-related questions for a chatbot. The system utilizes RAG by querying a vector database and incorporates metadata awareness in vector searches for improved results.
Key Takeaways
- A local LLM is being fine-tuned to categorize household-related questions using a dataset of approximately 850 entries.
- The baseline performance of the original Qwen 0.6B model was poor, achieving only 10% accuracy in categorizing questions without finetuning.
- The finetuning process utilizes the Unsloth framework and aims to improve the model's accuracy in classifying questions by teaching it to recognize specific metadata categories.
- The experiment highlights the importance of using a well-structured dataset and avoiding overfitting during the training process.
Community Sentiment
Positives
- Fine-tuning a local LLM like Qwen 0.6B can effectively categorize questions, demonstrating its potential for specific applications in text classification.
- The model's ability to invent new categories shows its flexibility, which could enhance its utility in dynamic classification tasks.
Concerns
- For trivial problems like subject classification, traditional methods like Scikit Learn may outperform fine-tuning a small LLM, raising questions about the necessity of using larger models.
- The model struggles with basic arithmetic questions, indicating potential limitations in its reasoning capabilities and reliability for straightforward queries.
