Summary
A recent paper published on arXiv critiques the reliance on cosine similarity as a measure of interpretability transfer in AI models, particularly when these models utilize quantized weights. The authors argue that cosine similarity can be misleading and propose that researchers should focus on reporting the noise floor and class separation metrics instead. These metrics provide a more accurate representation of how well interpretability is preserved during the quantization process, which is crucial for ensuring that AI models remain understandable and trustworthy after optimization.
Takeaways
- Cosine similarity may not be a reliable measure for interpretability transfer in quantized AI models.
