Computer Science/Discrete Mathematics Seminar I

Improved Private Information Retrieval Schemes from Matching Vectors and Derivatives
Swastik Kopparty
10:30am|Simonyi Hall 101 and Remote Access

Private Information Retrieval (PIR) is a method for a user to interact with t non-colluding servers and read some entry of a database of size n without revealing to the servers anything about which entry of the database was read. After a long line...

Locally Testable Codes with the Multiplication Property from High-dimensional Expanders
10:30am|Simonyi 101 and Remote Access

A locally testable code (LTC) is an error-correcting code equipped with a tester T that, given an input string x, queries only a small number of positions and rejects x with probability proportional to its distance from the code. Classic examples of...

Why Extension-Based Proofs Fail
Faith Ellen
10:30am|Simonyi Hall 101 and Remote Access

A valency argument is an elegant and well-known technique for proving impossibility results in distributed computing. It is an example of an extension-based proof, which is modelled as an interaction between a prover and a protocol. Even though...
