Abstract

fetched live from OpenAlex

Two-dimensional similarity-based image organizing studies how to place photos within 2D virtual canvas based on their visual contents so that the users can easily locate the desired photos. As an extension to our previous work [10], several improvements are made in this paper to allow better photo browsing experiences. For example, the new approach pre-orders all the photos so that a consistent set of photos is selected for display. This solves the photo flickering problem of our previous approach, which uses K-mean algorithm to dynamically select photos.The main focus of this paper however is on the evaluation of the effectiveness of different feature vectors for 2D photo organization. A performance metric is proposed to measure how well photos with similar visual contents are grouped together on the 2D canvas. Feature vectors generated using eight different low-level feature extraction approaches are tested. The evaluation results reveal the pros and cons of different feature extraction approaches, which can be a useful guide for developing new feature vectors.

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.
