TL;DR: This work constructs a general data-driven framework called Constrained Action-based Partially Observable Markov Decision Process (CAPOMDP) to induce effective pedagogical policies and induces two types of policies: CAPOMDPLG using learning gain as reward with the goal of improving students' learning performance, and CAPomDPTime using time as reward for reducing students' time on task.

2015 article

Anomaly detection in dynamic networks: a survey

Ranshous, S., Shen, S., Koutra, D., Harenberg, S., Faloutsos, C., & Samatova, N. F. (2015, March 21). Wiley Interdisciplinary Reviews Computational Statistics.

By: S. Ranshous n, S. Shen n, D. Koutra *, S. Harenberg n, C. Faloutsos * & N. Samatova n

author keywords: anomaly detection; dynamic networks; outlier detection; graph mining; dynamic network anomaly detection; network anomaly detection
topics (OpenAlex): Anomaly Detection Techniques and Applications; Network Security and Intrusion Detection; Complex Network Analysis Techniques
TL;DR: This work focuses on anomaly detection in static graphs, which do not change and are capable of representing only a single snapshot of data, but as real‐world networks are constantly changing, there has been a shift in focus to dynamic graphs,Which evolve over time. (via Semantic Scholar)
