PhD Seminar • Artificial Intelligence (Affective Computing) — Automatic Group-Level Emotion Recognition using Deep Learning

Aarti Malhotra, PhD candidate
David R. Cheriton School of Computer Science

We investigate a deep learning approach to classify emotions in group-level photos into three categories: (1) positive; (2) neutral; and (3) negative.

DSG Seminar Series • Just-in-Time Indexing: Rethinking Data Layout as a Compiler Problem

Indexing is a game of tradeoffs: Organize your data now and be rewarded with lower read latencies later. The question of whether, how, or when to organize has led to a proliferation of many different, often highly-specialized index structures.

Seminar • Algorithms and Complexity — The Combinatorics of Furthest and Nearest Values

Lily Wang, University of Waterloo

A classical problem asks us to find, for each element $A[i]$ of an array of integers, the position of the nearest smallest element. Similarly, we can ask about the dual problem: for each element of an array of integers $A[i]$, what is the position of the furthest smaller element?
