*Title:* The Lottery Ticket Hypothesis: On Sparse, Trainable Neural Networks

*Abstract:* I recently proposed the *lottery ticket hypothesis*: that the
dense neural networks we typically train have much smaller subnetworks
capable of reaching full accuracy from early in training. This hypothesis
raises (1) scientific questions about the nature of overparameterization in
neural network optimization and (2) practical questions about our ability
to accelerate training. In this talk, I will discuss established results
and the latest developments in my line of work on the lottery ticket
hypothesis, including the empirical evidence for these claims on small
vision tasks, changes necessary to scale these ideas to practical settings,
and the relationship between these subnetworks and their "stability" to the
noise of stochastic gradient descent. I will also describe my vision for
the future of research on this topic.

*Bio: *Jonathan Frankle is a fifth year PhD student at MIT, where he
empirically studies deep learning with Prof. Michael Carbin. His current
research focus is on the properties of sparse networks that allow them to
train effectively as embodied by his "Lottery Ticket Hypothesis" (ICLR 2019
best paper award). Jonathan also has an interest in technology policy: he
has worked closely with lawyers, journalists, and policymakers on topics in
AI policy and has taught at the Georgetown University Law Center. He earned
his BSE and MSE in computer science at Princeton and has previously spent
time at Google, Facebook, and Microsoft.
