Belief Propagation and the Stochastic Block Model

[Guest post by Thomas Orton who presented a lecture on this in our  physics and computation seminar --Boaz] Introduction This blog post is a continuation of the CS229R lecture series. Last week, we saw how certain computational problems like 3SAT exhibit a thresholding behavior, similar to a phase transition in a physical system. In this post, … Continue reading Belief Propagation and the Stochastic Block Model

Statistical Physics: an introduction in two parts

Statistical physics has deep connections to many computational problems, including statistical inference, counting and sampling, and optimization. Perhaps especially compelling are the field's insights and intuitions regarding "average-case complexity" and information-computation gaps. These are topics for which the traditional theoretical CS approaches seem ill-suited, while on the other hand statistical physics has supplied a rich … Continue reading Statistical Physics: an introduction in two parts

FOCS early registration deadline

[Message from Adi Rosen --Boaz] This is a kind reminder that the deadline for the early rate registration fees for FOCS 2018 is this Sunday, September 9, 2018. =================================== FOCS 2018 - Second Call for Participation =================================== https://www.irif.fr/~focs2018/ The 59th Annual IEEE Symposium on Foundations of Computer Science (FOCS 2018) will take place in Paris, France, … Continue reading FOCS early registration deadline

Black holes, paradoxes, and computational complexity

(Thanks so much to Scott Aaronson for giving me many pointers, insights, explanations, and corrections that greatly improved this post. As I'm a beginner to physics, the standard caveat holds doubly here: Scott is by no means responsible to any of my remaining technical mistakes and philosophical misconceptions.) One of the interesting features of physics … Continue reading Black holes, paradoxes, and computational complexity

Physics Envy

There is something cool about physics. Black holes, anti-matter, "God's particle": it all sounds so exciting. While our TCS "mental experiments" typically involve restricting the inputs of constant-depth circuits, physicists talk about jumping into black holes while holding a dictionary. Physicists also have a knack for names: notions such as "uncertainty principle" or "monogamy of … Continue reading Physics Envy

Beyond CRYPTO workshop: August 19

[Unrelated note: Huge congratulations to Costis Daskalakis - winner of the 2018 Nevanlinna medal!] As part of the CRYPTO 2018 conference (August 19-23, Santa Barbara, CA), there is a set of of affiliated events. The conference organizers (Tal Rabin, Elette Boyle, and Fabrice Benhamouda)  asked me  to advertise the workshop Beyond Crypto: A TCS Perspective (itself organized … Continue reading Beyond CRYPTO workshop: August 19

Theoryfest recap and FOCS call for workshops

I just came back from a wonderful TheoryFest in LA. There was a fantastic program,  including not just the paper presentations, but also tutorials, keynote talks, plenary short papers, and workshops, as well as other events including the junior/senior lunches, STOC 50th birthday, and probably others that I am forgetting right now. Still, while we … Continue reading Theoryfest recap and FOCS call for workshops
