Abstract

fetched live from OpenAlex

The indexing and retrieval of images in a multimedia database can be a very time consuming process, considering the amount of visual data stored in digital video libraries (DVLs). This paper proposes a semiautomated method to categorize images into groups as a pre-processing step in order to enable faster retrieval from a DVL. The wavelet transform is used to extract low-level features such as colour, texture and shape from images. The extracted features are employed to categorize the images using a novel neural network, the self-organizing tree map. The classification results are then used to train a feed forward neural network to identify the image classes an incoming query image belongs to. Initial experiments show promising results.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
