Scott Aaronson: Gentle Measurement of Quantum States and Differential Privacy Tuesday, November 20, 2018 - 4:00pm to 5:00pm We prove a surprising connection between gentle measurement (where one |

Jelani Nelson: Heavy Hitters via Cluster-Preserving Clustering Tuesday, November 15, 2016 - 4:00pm to 5:00pm Abstract: In the "heavy hitters" or "frequent items" problem, one must process a stream of items and report those items that occur frequently. For example, a telecommunications company may wish to find popular destination IP addresses in a packet stream across one of their links, |

Raghu Meka: Pseudorandomness- old problems, new methods, and current challanges Thursday, March 3, 2016 - 2:45pm to 3:45pm Abstract: In this talk I will survey recent results on two classical questions in complexity theory: derandomizing small-space algorithms and lower bounds for constant-depth circuits. |

Gillat Kol: Interactive Information Theory Thursday, December 3, 2015 - 4:00pm to 5:00pm Abstract: In a profoundly influential 1948 paper, Claude Shannon introduced information theory and used it to study one-way data transmission problems over different channels, both noisy and noiseless. That paper initiated the |

Omri Weinstein: Interactive Information Complexity and Applications Monday, November 16, 2015 - 4:00pm to 5:00pm Abstract: Over the past three decades, communication complexity has been extensively used to capture the fundamental limitations in diverse areas of theoretical computer science and modern computing systems. |

Robin Kothari: Separations in Query Complexity Using Cheat Sheets Tuesday, November 17, 2015 - 4:00pm to 5:00pm Abstract: 2015 has been an exciting year for query complexity. I'll survey some of the breakthroughs made this year and then talk about some very recent work with my collaborators Scott Aaronson and Shalev Ben-David. |

Benjamin Rossman: The Average Sensitivity Bounded-Depth Formulas Tuesday, October 13, 2015 - 4:15pm to 5:15pm Abstract: Hastad (1986) proved an exp( n^{1/d} ) lower bound on the size of depth d+1 (unbounded fan-in) boolean *circuits* computing the PARITY function. |

Oded Regev: Faster algorithms for the Shortest Vector Problem Thursday, April 23, 2015 - 4:15pm to 5:15pm Abstract: We give a randomized ~2^n-time algorithm for solving the Shortest Vector Problem (SVP) on n-dimensional lattices, improving on the previous best running time of 4^n by Micciancio and Voulgaris (STOC 2010). Despite being the fastest, the algorithm is arguably also the simplest in this |
