Using knowledge of the region of interest (ROI) in automatic image retrieval learning
Bibliographic record
Abstract
In this paper, we propose an automatic relevance feedback retrieval system using perceptually important features extracted from regions of interest. The system is implemented via self-learning using a self-organizing tree map (SOTM) neural network. Our proposed method involves the construction of regions of interest from retrieved images using edge flow model, and the grouping of the regions into a single perceptually significant entity. This knowledge is fed into a set of unsupervised relevance feedback learning modules based on the SOTM to guide the adaptation of relevance feedback parameters through a machine learning approach without user interaction. Optimal tradeoff between the user workload in the interactive process and user subjectivity is then be explored by incorporating a semi-automatic retrieval strategy. Experimental results indicate that this system, with automatic and semiautomatic adaptations, can minimize user interaction, optimize precision, as well as reduce performance errors caused user subjectivity.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
