Complexity of possibly gapped histogram and analysis of histogram [PDF]
Royal Society Open Science, 2018 We demonstrate that gaps and distributional patterns embedded within real-valued measurements are inseparable biological and mechanistic information contents of the system. Such patterns are discovered through data-driven possibly gapped histogram, which

Histogram Layers for Texture Analysis [PDF]
IEEE Transactions on Artificial Intelligence, 2022 An essential aspect of texture analysis is the extraction of features that describe the distribution of values in local, spatial regions. We present a localized histogram layer for artificial neural networks. Instead of computing global histograms as done previously, the proposed histogram layer directly computes the local, spatial distribution of ...
