Title
Dither NN: An Accurate Neural Network with Dithering for Low Bit-Precision Hardware
Abstract
Energy-constrained neural network processing is in high demanded for various mobile applications. Binary neural network aggressively enhances the computational efficiency, and in contrast, it suffers from degradation of accuracy due to its extreme approximation. We propose a novel accurate neural network model based on binarization and "dithering" that distributes the quantization error to neighboring pixels. The quantization errors in the binarization are distributed in the plane, so that a pixel in the multi-level source expression more accurately represented in the resulting binarized plane by multiple pixels. We designed a low-overhead binary-based hardware architecture for the proposed model. The evaluation results show that this method can be realized with a few additional lightweight hardware components.
