$F_β$-plot -- a visual tool for evaluating imbalanced data classifiers

no code implementations11 Apr 2024 Szymon Wojciechowski, Michał Woźniak

Although it is pretty common to have metrics indicating the classification quality within each class, for the end user, the analysis of several such metrics is then required, which in practice causes difficulty in interpreting the usefulness of a given classifier.

Continual Learning with Weight Interpolation

2 code implementations5 Apr 2024 Jędrzej Kozal, Jan Wasilewski, Bartosz Krawczyk, Michał Woźniak

Continual learning poses a fundamental challenge for modern machine learning systems, requiring models to adapt to new tasks while retaining knowledge from previous ones.

A Natural Gas Consumption Forecasting System for Continual Learning Scenarios based on Hoeffding Trees with Change Point Detection Mechanism

1 code implementation7 Sep 2023 Radek Svoboda, Sebastian Basterrech, Jędrzej Kozal, Jan Platoš, Michał Woźniak

Forecasting natural gas consumption, considering seasonality and trends, is crucial in planning its supply and consumption and optimizing the cost of obtaining it, mainly by industrial entities.

Transfer of knowledge among instruments in automatic music transcription

no code implementations30 Apr 2023 Michał Leś, Michał Woźniak

Achieved results prove that using synthesized data for training may be a good base for pretraining general-purpose models, where the task of transcription is not focused on one instrument.

Scalable handwritten text recognition system for lexicographic sources of under-resourced languages and alphabets

no code implementations28 Mar 2023 Jan Idziak, Artjoms Šeļa, Michał Woźniak, Albert Leśniak, Joanna Byszuk, Maciej Eder

Our study provides a working solution that reads the cards, and links their lemmas to a searchable list of dictionary entries, for a large historical dictionary entitled the Dictionary of the 17th- and 18th-century Polish, which comprizes 2. 8 million index cards.

Employing chunk size adaptation to overcome concept drift

no code implementations25 Oct 2021 Jędrzej Kozal, Filip Guzy, Michał Woźniak

Additionally, the possibility of concept drift appearance causes that the used algorithms must be ready for the continuous adaptation of the model to the changing data distributions.

RB-CCR: Radial-Based Combined Cleaning and Resampling algorithm for imbalanced data classification

1 code implementation9 May 2021 Michał Koziarski, Colin Bellinger, Michał Woźniak

Our $5\times2$ cross-validated results on 57 benchmark binary datasets with 9 classifiers show that RB-CCR achieves a better precision-recall trade-off than CCR and generally out-performs the state-of-the-art resampling methods in terms of AUC and G-mean.

Combined Cleaning and Resampling Algorithm for Multi-Class Imbalanced Data with Label Noise

no code implementations7 Apr 2020 Michał Koziarski, Michał Woźniak, Bartosz Krawczyk

The proposed method utilizes an energy-based approach to modeling the regions suitable for oversampling, less affected by small disjuncts and outliers than SMOTE.
