Trojan Horse Hunt in Time Series Forecasting for Space Operations

no code implementations2 Jun 2025 Krzysztof Kotowski, Ramez Shendy, Jakub Nalepa, Przemysław Biecek, Piotr Wilczyński, Agata Kaczmarek, Dawid Płudowski, Artur Janicki, Evridiki Ntagiou

Participants are provided with 1) a large public dataset of real-life multivariate satellite telemetry (without triggers), 2) a reference model trained on the clean data, 3) a set of poisoned neural hierarchical interpolation (N-HiTS) models for time series forecasting trained on the dataset with injected triggers, and 4) Jupyter notebook with the training pipeline and baseline algorithm (the latter will be published in the last month of the competition).

MASCOTS: Model-Agnostic Symbolic COunterfactual explanations for Time Series

no code implementations28 Mar 2025 Dawid Płudowski, Francesco Spinnato, Piotr Wilczyński, Krzysztof Kotowski, Evridiki Vasileia Ntagiou, Riccardo Guidotti, Przemysław Biecek

Unlike existing approaches that either depend on model structure or autoencoder-based sampling, MASCOTS directly generates meaningful and diverse counterfactual observations in a model-agnostic manner, operating on both univariate and multivariate data.

Improved robust weighted averaging for event-related potentials in EEG

1 code implementation Biocybernetics and Biomedical Engineering 2019 Krzysztof Kotowski, Katarzyna Stapor, Jacek Leski

The areas of improvement include significantly lower averaging error (45% lower RMSE and 37% lower maximum difference than for original implementation) and increased robustness to local minima, strong outliers and corrupted epochs common to real-life EEG signals, especially from low-cost devices.
