Join us at TTIC from May 23rd-24th for talks and activities relevant to the Collaboration on the Theoretical Foundations of Deep Learning.

  • Scientific Program: beginning Tuesday, May 23rd at 11 AM CT, ending Wednesday, May 24th at 4 PM CT.
  • Full Program: The meeting will conclude with a picnic at The Point after the scientific program ends, on Wednesday, May 24th from 4 PM CT to 8 PM.

See the schedule below for the list of talks by internal members of the collaboration and external speakers. We have also planned a panel session, a “research speed dating” event, and a discussion session for research topics/open problems for students, postdocs, and faculty to enjoy.

Remote participation will be accommodated; see below.


Hotel accommodations will be at The Study Hotel, located in Hyde Park.
