Hi, There is a talk today at McGill on "Spectral Methods for Learning Finite State Machines", details below. It seems like it could be really interesting. Cheers, Aaron ---------- Forwarded message ---------- From: Doina Precup <dprecup(a)cs.mcgill.ca> Date: Sat, Sep 15, 2012 at 9:26 PM Subject: Fwd: Visitor and Talk (Monday 2:30) about learning finite automata To: Aaron Courville <courvila(a)iro.umontreal.ca> Hi Aaron, Please post this to the LISA mailing list. BTW, if I should be sending these announcements to someone else, let me know Thank you, Doina Begin forwarded message: > From: Doina Precup <dprecup(a)cs.mcgill.ca> > Date: September 15, 2012 9:24:26 PM EDT > To: labrl(a)cs.mcgill.ca > Cc: Denis Therien <denis(a)cs.mcgill.ca> > Subject: Visitor and Talk (Monday 2:30) about learning finite automata > > Hi everyone, > > Borja Balle Pigem will be visiting Monday-Thursday next week. He has been doing very interesting work on spectral methods for learning automata, related to many of our interests in learning with partial observability.

deep learning tutorial starting tomorrow 11h30
by Yoshua Bengio 13 Sep '12

13 Sep '12

Hi all, In the next few IFT6266 lectures, I plan to go through the deep learning / representation tutorial I gave at the IPAM deep learning summer school in July (http://www.ipam.ucla.edu/programs/gss2012/) Classes are Monday 11h30-13h30 (room Z-255) and Thursday 9h30-11h30 (room Z-210), starting tomorrow. I expect this to last 3 or 4 lectures. Everyone is welcome to attend. An outline of the lectures and the slides are there: http://www.iro.umontreal.ca/~bengioy/talks/deep-learning-gss2012.html -- Yoshua
