Abstract: Deep learning (DL)-powered intelligence embedded into numerous daily-life devices promises to transform the quality of human life. Despite this great promise, there is a vast and increasing gap between the prohibitive complexity of powerful DL algorithms and the constrained resources in daily-life devices. While DL accelerators have the potential to close the aforementioned immense gap and push forward green AI, their power has yet to be unleashed due to the following fundamental challenges: (1) fast DL algorithm advances vs. slow DL accelerator development, and (2) the promise of algorithm and accelerator co-search vs. the lack of such co-search. Therefore, it is imperative to develop innovative techniques that can expedite the development of optimal DL accelerators and unlock the promise of co-searching for optimal DL algorithms and accelerators for maximizing their achievable hardware efficiency.

In this talk, I will present our recently developed techniques towards DL network-accelerator co-search, serving as a timely holistic effort toward addressing the aforementioned challenges. Specifically, I will start by introducing our techniques for designing hardware-aware DL algorithms (i.e., top-down efforts) and algorithm-aware DL accelerators (i.e., bottom-up efforts), which help us to gain important insights for understanding their design space and optimization. Then, I will share our first-of-their-kind techniques that are among the very first generic efforts to enable simultaneous searching for optimal DL algorithms and accelerators (i.e., bridging efforts) to maximize both task accuracy and hardware efficiency. Finally, I will conclude my talk with exciting (1) applications of our co-search framework and (2) pointers to future directions.
