Partitioning-Guided K-Means for Effective Empty Cluster Resolution in Extreme Model Compression

Creator:: Huang, Tianhong
Abstract:: Compactness in deep learning can be critical to a model’s viability in low-resource applications, and a common approach to extreme model compression is quantization. We consider Iterative Product Quantization (iPQ) with Quant-Noise [Fan et al., 2020] to be state-of-the-art in this area, but this quantization framework suffers from preventable inference...
