Abstract

fetched live from OpenAlex

In this paper, we propose the bounded Laplace mixture model (BLMM). We also propose a new modeling scheme for wavelet coefficients based on BLMM and we apply it to image clustering and content based image retrieval (CBIR). The clustering stage is also performed by BLMM. In the proposed applications, BLMM is applied for feature extraction where each image is decomposed into a set of wavelet subspaces and a two component BLMM is adopted to illustrate the statistical characteristics of the wavelet coefficients for each wavelet subspace. The model parameters adapted from proposed model, reflect the image features of wavelet domain for each subspace and selected to formulate the feature space which is further used in clustering and CBIR. UIUC, KTH-TIPS and DTD databases are considered to demonstrate the viability and effectiveness of proposed algorithm in image clustering and CBIR. From set of experiments, BLMM has demonstrated its effectiveness in modeling the wavelet coefficients in feature extraction, image clustering and CBIR.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
