FOCUS & RePAIR: Mitigating Text Degeneration via Token-Level Guidance for Pruned Large Language Models
TL;DR
FOCUS and RePAIR are two novel token-level guidance methods designed to mitigate text degeneration in pruned large language models (LLMs). These techniques effectively reduce repetition and enhance the quality of generated text during open-ended and instruction-based tasks.
✦ Why It Matters
Implement FOCUS and RePAIR techniques to enhance text generation quality in your pruned LLMs today.
Key Takeaways
- Apply FOCUS to prioritize high-confidence outputs in model training.
- Use RePAIR to encourage diverse token selections during generation.
- Monitor for repetition loops in generated text to assess model performance.
- Experiment with both methods to find the best fit for your applications.
How It Works
FOCUS reweights the training process to focus on high-confidence outputs from a teacher model, reducing the likelihood of generating repetitive text. RePAIR introduces a margin loss that encourages the model to explore plausible alternatives rather than committing to early repetitive outputs, thus promoting diversity in generated text.
