Training deep neural networks (DNNs) can be expensive and slow, consuming enormous numbers of compute-hours on parallel machines. This talk will present results on using novel search procedures over programs to reduce training time. In particular, instead of greedily applying program-improving transformations to compute a single improved program, we search a space of programs, considering many possible candidates guided by a global cost function. Application of search-based optimization to two separate problems will be discussed: improving the partitioning and distribution of training data, and reducing the execution time of the DNN computation graph. Both methods speedup training by up to a factor of 3 over current state-of-the-art systems.

Alex received his Bachelors degree in Computer Science and Music from Bowling Green State University in 1983 and his Ph.D. from Cornell University in 1988. Alex was a Research Staff Member at the IBM Almaden Research Center (1988-1993) and a Professor in the EECS department at UC Berkeley (1993-2003) before joining the Stanford faculty in 2003. His research interest is in areas related to programming languages. He is an ACM Fellow, a recipient of ACM SIGPLAN’s Programming Languages Achievement Award and Phi Beta Kappa’s Teaching Award, and a former chair of the Stanford Computer Science Department.
