Master’s Thesis Presentation / Seminar • Algorithms and Complexity — Minimum Shared-Power Edge Cut

Kshitij Jain, Master’s candidate
David R. Cheriton School of Computer Science

We introduce a problem called the Minimum Shared-Power Edge Cut (MSPEC). The input to the problem is an undirected edge-weighted graph with distinguished vertices s and t, and the goal is to find an s-t cut by assigning "powers'' at the vertices and removing an edge if the sum of the powers at its endpoints is at least its weight. The objective is to minimize the sum of the assigned powers.

Master’s Thesis Presentation • Data Systems — Refresh Strategies for Continuous Active Learning

Nimesh Ghelani, Master’s candidate
David R. Cheriton School of Computer Science

High recall information retrieval is crucial to tasks such as electronic discovery and systematic review. Continuous Active Learning (CAL) is a technique where a human assessor works in loop with a machine learning model; the model presents a set of documents likely to be relevant and the assessor provides relevance feedback.
