Dave has done foundational work and is a leading thinker in the fields of probabilistic graphical models and variational inference. He is also an excellent speaker. His talk should not be missed!
Best, Laurent

This week we have * David Blei* from * Columbia University * giving a talk on * The Blessings of Multiple Causes* at * 10h30* at *Mila Auditorium*.
Will this talk be streamed https://mila.bluejeans.com/809027115/webrtc? Yes
David will also be visiting Mila on *Thursday (7th March)*. To that end we organized a discussion group on *Causal Inference* from *2pm *to *3pm* in *room A14*.
A bunch of you asked for 1-1 and 2-1 meetings : The schedule is also set during that day, I’ll send the invites by tomorrow :)
See you there! The Tea Talk Team
*TITLE* The Blessings of Multiple Causes
*ABSTRACT* Causal inference from observational data is a vital problem, but it comes with strong assumptions. Most methods require that we observe all confounders, variables that correlate to both the causal variables (the treatment) and the effect of those variables (how well the treatment works). But whether we have observed all confounders is a famously untestable assumption. We describe the deconfounder, a way to do causal inference from observational data with weaker assumptions that the classical methods require. How does the deconfounder work? While traditional causal methods measure the effect of a single cause on an outcome, many modern scientific studies involve multiple causes, different variables whose effects are simultaneously of interest. The deconfounder uses the multiple causes as a signal for unobserved confounders, combining unsupervised machine learning and predictive model checking to perform causal inference. We describe the theoretical requirements for the deconfounder to provide unbiased causal estimates, and show that it requires weaker assumptions than classical causal inference. We analyze the deconfounder's performance in three types of studies: semi-simulated data around smoking and lung cancer, semi-simulated data around genomewide association studies, and a real dataset about actors and movie revenue. The deconfounder provides a checkable approach to estimating close-to-truth causal effects. This is joint work with Yixin Wang. [*] https://arxiv.org/abs/1805.06826
