Talk by Karen Ullrich

You are all cordially invited to the AMLab seminar on Tuesday March 7 at 16:00 in C3.163, where Karen Ullrich will give a talk titled “Soft Weight-Sharing for Neural Network Compression”. Afterwards there are the usual drinks and snacks!

Abstract: The success of deep learning in numerous application domains created the desire to run and train them on mobile devices. This however, conflicts with their computationally, memory and energy intense nature, leading to a growing interest in compression. Recent work by Han et al. (2015a) propose a pipeline that involves retraining, pruning and quantization of neural network weights, obtaining state-of-the-art compression rates. In this paper, we show that competitive compression rates can be achieved by using a version of ”soft weight-sharing” (Nowlan & Hinton, 1992). Our method achieves both quantization and pruning in one simple (re-)training procedure. This point of view also exposes the relation between compression and the minimum description length (MDL) principle.
