Online Transition-Based Feature Generation for Anomaly Detection in Concurrent Data Streams

no code implementations17 Aug 2023 Yinzheng Zhong, Alexei Lisitsa

In this paper, we introduce the transition-based feature generator (TFGen) technique, which reads general activity data with attributes and generates step-by-step generated data.

Machine learning discovers invariants of braids and flat braids

no code implementations22 Jul 2023 Alexei Lisitsa, Mateo Salles, Alexei Vernitski

We use machine learning to classify examples of braids (or flat braids) as trivial or non-trivial.

Logic Rules Meet Deep Learning: A Novel Approach for Ship Type Classification

1 code implementation1 Nov 2021 Manolis Pitsikalis, Thanh-Toan Do, Alexei Lisitsa, Shan Luo

The shipping industry is an important component of the global trade and economy, however in order to ensure law compliance and safety it needs to be monitored.

Untangling Braids with Multi-agent Q-Learning

no code implementations29 Sep 2021 Abdullah Khan, Alexei Vernitski, Alexei Lisitsa

We interface the braid untangling problem with the OpenAI Gym environment, a widely used way of connecting agents to reinforcement learning problems.

Representation and Processing of Instantaneous and Durative Temporal Phenomena

1 code implementation27 Aug 2021 Manolis Pitsikalis, Alexei Lisitsa, Shan Luo

In this paper, we propose a new logic based temporal phenomena definition language, specifically tailored for Complex Event Processing, that allows the representation of both instantaneous and durative phenomena and the temporal relations between them.
