MSc thesis project proposal
 Efficient Transformer for Keyword Spotting
Always-on keyword spotting on ultra-low-power integrated circuits is a hot topic in chip design for artificial intelligence systems. Previous work used spiking neural networks (SNNs), Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs), but the state-of-the-art accuracy was recently achieved by transformers. However, transformers have a large memory footprint and many arithmetic operations; thus, it is difficult to be employed on tiny embedded systems with scarce resources. In this project, you will work on developing algorithmic methods to compress the model of transformer neural networks to reduce its memory and arithmetic cost.
