Spatial Clustering Approach for Vessel Path Identification

1 code implementation9 Mar 2024 Mohamed Abuella, M. Amine Atoui, Slawomir Nowaczyk, Simon Johansson, Ethan Faghan

This paper addresses the challenge of identifying the paths for vessels with operating routes of repetitive paths, partially repetitive paths, and new paths.

Forecasting Auxiliary Energy Consumption for Electric Heavy-Duty Vehicles

no code implementations27 Nov 2023 Yuantao Fan, Zhenkan Wang, Sepideh Pashami, Slawomir Nowaczyk, Henrik Ydreskog

Given that the employed groupings correspond to relevant sub-populations, the associations between the input features and the target values are consistent within each cluster but different across clusters.

Heterogeneous Federated Learning via Personalized Generative Networks

no code implementations25 Aug 2023 Zahra Taghiyarrenani, Abdallah Alabdallah, Slawomir Nowaczyk, Sepideh Pashami

In this paper, we provide theoretical proof that minimizing heterogeneity between clients facilitates the convergence of a global model for every single client.

Learning Causal Mechanisms through Orthogonal Neural Networks

1 code implementation5 Jun 2023 Peyman Sheikholharam Mashhadi, Slawomir Nowaczyk

Addressing this crucial discrepancy between human and machine intelligence is an important challenge for pattern recognition systems.

Information-Gathering in Latent Bandits

no code implementations8 Jul 2022 Alexander Galozy, Slawomir Nowaczyk

In the latent bandit problem, the learner has access to reward distributions and -- for the non-stationary variant -- transition models of the environment.

Wisdom of the Contexts: Active Ensemble Learning for Contextual Anomaly Detection

no code implementations27 Jan 2021 Ece Calikus, Slawomir Nowaczyk, Mohamed-Rafik Bouguelia, Onur Dikmen

Furthermore, the results support our initial hypothesis that there is no single perfect context that successfully uncovers all kinds of contextual anomalies, and leveraging the "wisdom" of multiple contexts is necessary.

A New Bandit Setting Balancing Information from State Evolution and Corrupted Context

1 code implementation16 Nov 2020 Alexander Galozy, Slawomir Nowaczyk, Mattias Ohlsson

We present an algorithm that uses a referee to dynamically combine the policies of a contextual bandit and a multi-armed bandit.

No Free Lunch But A Cheaper Supper: A General Framework for Streaming Anomaly Detection

no code implementations16 Sep 2019 Ece Calikus, Slawomir Nowaczyk, Anita Sant'Anna, Onur Dikmen

To date, there exists no single general method that has been shown to outperform the others across different anomaly types, use cases and datasets.

Machine learning in healthcare -- a system's perspective

no code implementations14 Sep 2019 Awais Ashfaq, Slawomir Nowaczyk

Though the application of ML on health data have shown incremental improvements for clinical decision support, ML has a much a broader potential to restructure care delivery as a whole and maximize care value.
