    Balancing signature variance between local and global minima/maxima: Restricted maximum likelihood (REML) classification and the search for plagioclimax by N. Manspeizer, A. Karnieli

    Published 2025-12-01
    “…Entropy (a measure of disorder) and emptiness (a proxy for fragmentation) measures were designed into bin tables and examined relative to the variance in the spectral signatures. A restricted maximum likelihood (REML) classifier that relies on limiting variance was chosen to identify local maximum clusters (the unique plagioclimax classes), and the five classification results were compared. …”

    Machine learning with analysis-of-variance-based method for identifying rice varieties by Nabin Kumar Naik, M. Venkata Subbarao, Prabira Kumar Sethy, Santi Kumari Behera, Gyana Ranjan Panigrahi

    Published 2024-12-01
    “…Using a combination of 12 morphological features, four shape features, and 90 color features obtained from five different color spaces, 106 features were extracted from the images. An analysis of variance (ANOVA) was employed to select high-rank features, which were then fed to a support vector machine (SVM) for classification. …”

    IG-FIQA: Improving Classifiability-Based Face Image Quality Assessment Through Intra-Class Variance Guidance by Minsoo Kim, Gi Pyo Nam, Haksub Kim, Haesol Park, Ig-Jae Kim

    Published 2025-01-01
    “…In the realm of face image quality assessment (FIQA), methods based on sample relative classification have shown impressive performance. However, the quality scores used as pseudo-labels assigned from images of classes with low intra-class variance could be unrelated to the actual quality in such methods. …”
