Abstract

fetched live from OpenAlex

Deep neural nets enabled sophisticated information extraction out of images, including video frames. Recently, there has been interest in techniques and algorithms to enable interactive declarative query processing of objects appearing on video frames and their associated interactions on the video feed. SVQ++ is a system for declarative querying on real-time video streams involving objects and their interactions. The system utilizes a sequence of inexpensive and less accurate models (filters), called Progressive Filters (PF), to detect the presence of the query specified objects on frames, and a filtering approach, called Interaction Sheave (IS), to effectively prune frames that are not likely to contain interactions. We demonstrate that this system can efficiently identify frames in a streaming video in which an object is interacting with another in a specific way, increasing the frame processing rate dramatically and speed up query processing by at least two orders of magnitude depending on the query.

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.
