DenseShift: Towards Accurate and Efficient Low-Bit Power-of-Two Quantization

ICCV 2023poster

Efficiently deploying deep neural networks on low-resource edge devices is challenging due to their ever-increasing resource requirements. To address this issue, researchers have proposed multiplication-free neural networks, such as Power-of-Two quantization, or also known as Shift networks, which a…

Understanding Neural Network Binarization with Forward and Backward Proximal Quantizers

NeurIPS 2023poster

In neural network binarization, BinaryConnect (BC) and its variants are considered the standard. These methods apply the sign function in their forward pass and their respective gradients are backpropagated to update the weights. However, the derivative of the sign function is zero whenever defined,…

S$^3$: Sign-Sparse-Shift Reparametrization for Effective Training of Low-bit Shift Networks

NeurIPS 2021poster

Shift neural networks reduce computation complexity by removing expensive multiplication operations and quantizing continuous weights into low-bit discrete values, which are fast and energy-efficient compared to conventional neural networks. However, existing shift networks are sensitive to the weig…
