Enhancing Dimension-Reduced Scatter Plots with Class and Feature Centroids

1 code implementation29 Mar 2024 Daniel B. Hier, Tayo Obafemi-Ajayi, Gayla R. Olbricht, Devin M. Burns, Sasha Petrenko, Donald C. Wunsch II

We illustrate the utility of this approach with data derived from the phenotypes of three neurogenetic diseases and demonstrate how the addition of class and feature centroids increases the interpretability of scatter plots.

Incremental cluster validity index-guided online learning for performance and robustness to presentation order

no code implementations17 Aug 2021 Leonardo Enzo Brito da Silva, Nagasharath Rayapati, Donald C. Wunsch II

The model achieves improved accuracy and robustness to ordering effects by integrating an online iCVI framework as module B of a topological adaptive resonance theory predictive mapping (TopoARTMAP) -- thereby being named iCVI-TopoARTMAP -- and by employing iCVI-driven post-processing heuristics at the end of each learning step.

iCVI-ARTMAP: Accelerating and improving clustering using adaptive resonance theory predictive mapping and incremental cluster validity indices

1 code implementation22 Aug 2020 Leonardo Enzo Brito da Silva, Nagasharath Rayapati, Donald C. Wunsch II

This paper presents an adaptive resonance theory predictive mapping (ARTMAP) model which uses incremental cluster validity indices (iCVIs) to perform unsupervised learning, namely iCVI-ARTMAP.

A Survey of Adaptive Resonance Theory Neural Network Models for Engineering Applications

no code implementations4 May 2019 Leonardo Enzo Brito da Silva, Islam Elnabarawy, Donald C. Wunsch II

This survey samples from the ever-growing family of adaptive resonance theory (ART) neural network models used to perform the three primary machine learning modalities, namely, unsupervised, supervised and reinforcement learning.
