Solid Harmonic Wavelet Bispectrum for Image Analysis

Advanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Usage of the term provenance in LIS literature: An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Provenance is the story of how something has come to be. In this paper, we provide a systematic literature review to categorize the various notions of provenance in Information Sciences. The goal of this review is to paint a broader picture of the multiple uses of provenance at play and to enhance our understanding of the importance of ...
