Data structure > labels? Unsupervised heuristics for SVM hyperparameter estimation

no code implementations3 Nov 2021 Michał Cholewa, Michał Romaszewski, Przemysław Głomb

Classification is one of the main areas of pattern recognition research, and within it, Support Vector Machine (SVM) is one of the most popular methods outside of field of deep learning -- and a de-facto reference for many Machine Learning approaches.

Improving Autoencoder Training Performance for Hyperspectral Unmixing with Network Reinitialisation

no code implementations28 Sep 2021 Kamil Książek, Przemysław Głomb, Michał Romaszewski, Michał Cholewa, Bartosz Grabowski, Krisztián Búza

Neural networks, in particular autoencoders, are one of the most promising solutions for unmixing hyperspectral data, i. e. reconstructing the spectra of observed substances (endmembers) and their relative mixing fractions (abundances), which is needed for effective hyperspectral analysis and classification.
