The classical Cheeger’s inequality relates the edge conductance of a graph and the second smallest eigenvalue of the Laplacian matrix. Recently, Olesker-Taylor and Zanetti discovered a Cheeger-type inequality connecting the vertex expansion of a graph and the maximum reweighted second smallest eigenvalue of the Laplacian matrix.

PhD Defence • Data Systems • Memory Power Consumption in Main-Memory Database Systems

Please note: This PhD defence will take place online.

Alexey Karyakin, PhD candidate
David R. Cheriton School of Computer Science

Supervisor: Professor Ken Salem

In main-memory database systems, memory can consume a substantial amount of power, comparable to that of the processors. However, existing memory power-saving mechanisms are much less effective than processor power management. Unless the system is almost idle, memory power consumption will be high.

The task of Grammar Error Correction (GEC) entails designing a system that is capable of performing text improvement and correcting semantic/syntax inconsistencies in a text span (sentence), while grammar error detection (GED) is used to classify whether a sentence is correct or not.

On Saturday, October 1, 2022, Distinguished Professor Emeritus Don Cowan (MSc ’61, PhD ’65) received an honorary J.W. Graham Medal in Innovation and Computing at the Wes Graham Symposium.

The award recognizes Professor Cowan’s “extensive academic career, pioneering research in mathematics and computer science, entrepreneurial spirit, and devotion to mentorship and knowledge sharing.”

Enabling secure outsourced analytics with practical performance has been a long-standing research challenge in the database community. In this talk, I will present our work towards realizing this vision with Secrecy, a new framework for secure relational analytics in untrusted clouds.

PhD candidate Ryusuke Sugimoto and Professors Christopher Batty and Toshiya Hachisuka have won a best paper award at SCA 2022. The 21st ACM SIGGRAPH / Eurographics Symposium on Computer Animation took place virtually and in person this year at Durham University in the United Kingdom from September 13 to 15.
