The Impact of the Calibration Dataset for AutoRound and AWQ Quantization

The Kaitchup – AI on a Budget • 39 implied HN points • 31 Oct 24
🕹 Technology AI Data science Machine Learning Quantization Model optimization
  1. Quantization helps reduce the size of large language models, making them easier to run, especially on consumer GPUs. For instance, using 4-bit quantization can shrink a model's size by about a third.
  2. Calibration datasets are crucial for improving the accuracy of quantization methods like AWQ and AutoRound. The choice of the dataset impacts how well the quantization performs.
  3. Most quantization tools use a default English-language dataset, but results can vary with different languages and datasets. Testing various options can lead to better outcomes.

But have you considered writing your own evaluation metric?

🕹 Technology Machine Learning Evaluation Metrics Customization Domain Knowledge Model optimization
  1. Consider writing your own evaluation metric in machine learning to better align with your specific goals and domain knowledge.
  2. Off-the-shelf metrics like mean squared error come with assumptions that may not always fit your model's needs, so customizing metrics can be beneficial.
  3. Communication with domain experts and incorporating domain knowledge into evaluation metrics can lead to more effective model performance assessments.

Edge 459: Quantization Plus Distillation

TheSequence • 77 implied HN points • 24 Dec 24
🕹 Technology Machine Learning AI Models Data science Model optimization Deep Learning
  1. Quantized distillation helps make deep neural networks smaller and faster by combining two techniques: knowledge distillation and quantization.
  2. This method transfers knowledge from a high-precision model (teacher) to a low-precision model (student) without losing much accuracy.
  3. Using soft targets from the teacher model can reduce problems that often come with using simpler models, keeping performance strong.

Super Weights in LLMs - How Pruning Them Destroys a LLM's Ability to Generate Text ?

Machine Learning Diaries • 3 implied HN points • 18 Nov 24
🕹 Technology Machine Learning Artificial Intelligence Data science Model optimization Software Development
  1. Super weights are very important for how well large language models (LLMs) perform. Even though they're a tiny part of the model, they can greatly affect the results.
  2. If a super weight is removed, it can ruin the model's ability to generate clear text and make predictions. Just taking out one of these weights can cause a huge drop in performance.
  3. Removing regular outlier weights doesn't harm performance much, but losing just one super weight is much worse than taking out a lot of other weights combined.
