Abstract

fetched live from OpenAlex

In recent years, with the development of network technology, countless videos are produced every day. Many achievements have also been made in the field of action recognition in computer vision. Training action recognition models requires a large number of labeled samples, but in reality, the amount of data is scarce, and it is extremely difficult to obtain a large amount of data due to costs and other reasons. The few-shot learning aims to solve the problem of using several samples to learn new categories. This paper combs the relevant research in recent years of few-shot action recognition technology. According to the classification of training process, this paper summarizes the research progress and typical models of few-shot action recognition from the perspectives of data processing, feature embedding, feature augmentation, and metric learning; finally points out the challenges faced by current research and the future development directions.

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.
