DESCRIPTION:Title: Accelerating Machine Learning with Fast Stochastic
Algorithms\nSpeaker: Christopher De Sa\nAbstract: As machine learning
applications become larger and more widely used\, there is an increasing
need for efficient systems solutions. The performance of essentially all
machine learning applications is limited by bottlenecks\, such as
parallelizability and memory bandwidth\, with effects that cut across
traditional layers in the software stack. The key property that helps us
address these bottlenecks is the fact that machine learning problems are
statistical and thus have some built-in error tolerance: this gives us
additional degrees of freedom that we can use when designing and
optimizing machine learning algorithms. To use these extra degrees of
freedom effectively\, we need to develop techniques that can leverage
noise-tolerance to increase the throughput of our systems\, while
provably having little effect on their accuracy.\n\n \n\nIn practice\,
there is a broad class of algorithms\, stochastic iterative algorithms\,
that often determine the performance of machine learning systems. In
this talk\, I will describe several methods that can be applied to speed
up stochastic iterative algorithms in a principled way by using
high-level structural information about a problem. I will also discuss
future research directions\, including a new approach to getting highly
accurate solutions while mostly using energy-efficient low-precision
computation.
