Normalization in Proportional Feature Spaces

no code implementations17 Sep 2024 Alexandre Benatti, Luciano da F. Costa

The subject of features normalization plays an important central role in data representation, characterization, visualization, analysis, comparison, classification, and modeling, as it can substantially influence and be influenced by all of these activities and respective aspects.

Supervised Pattern Recognition Involving Skewed Feature Densities

no code implementations2 Sep 2024 Alexandre Benatti, Luciano da F. Costa

Several interesting results are described and discussed, including the enhanced potential of the dissimilarity index for classifying datasets with right skewed feature densities, as well as the identification that the sharpness of the comparison between data elements can be independent of the respective supervised classification performance.

Multilayer Multiset Neuronal Networks -- MMNNs

no code implementations28 Aug 2023 Alexandre Benatti, Luciano da Fontoura Costa

These features allow multiset neurons, which are based on the coincidence similarity operation, to perform effective pattern recognition applications, including the challenging task of image segmentation.
