Talk Title: Efficient Deep Learning for Computer Vision
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Deep neural networks are empowering increasingly more applications in computer vision. To deploy deep learning to more devices (edge, mobile, AR/VR glasses), we need to tackle numerous challenges to make deep learning more efficient. In this talk, we will focus on two important aspects of efficiency: model efficiency and data efficiency. Improving model efficiency enables packing stronger AI capabilities to devices with limited compute, while better data efficiency unblocks more applications constrained by lack of data. This talk will first introduce the FBNet series of work [1-4], which studies neural architecture search (NAS) methods to automatically develop compute-efficient models to achieve better accuracy-efficiency trade-offs. For data efficiency, this talk will introduce OTTER [5], a data-efficient algorithm that uses language to train vision models to recognize images in a zero-shot manner -- being able to recognize new classes without needing extra labels.
