Abstract

fetched live from OpenAlex

In this paper we propose a new approach to video based face recognition. Our work is based on the Sparse Classification approach which assumes that each test sample can be formed by a linear combination of the training samples of the correct class. Based on this assumption, we formulate the classification problem as one of joint sparse recovery of Multiple Measurement Vectors (MMV). This requires solving an NP hard problem. This problem has not been solved earlier; thus we derive an algorithm for solving it. The experimental evaluation is carried on the VidTIMIT database. The proposed method is compared against an HMM based method for video based face recognition and the modified Sparse Classification method. The results show that the proposed method outperforms both these methods.

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.

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.
