How does AWQ work without a calibration dataset?

Context

You mentioned:

"This repo quantizes the model using data-free quantization tool. (no calibration dataset was involved)"

Question

You state this is a calibration-free approach, but AWQ (Activation-aware Weight Quantization) typically requires calibration data to:

  1. Identify important weights
  2. Understand activation patterns
  3. Perform smoothing before W4A16 quantization

Could you clarify your approach?

Are you using one of the following strategies:

  • Pattern recognition: Analyzing weight distributions to identify salient weights deterministically?
  • Activation awareness without calibration: Using some heuristic or model properties (e.g., layer norms, gradients) to approximate activation importance?
  • Simplified quantization: Performing basic W4A16 quantization without the activation-aware smoothing step?

Or is there another approach I'm missing?
