Abstract
Neural architecture search (NAS) has significantly advanced the automatic design of convolutional neural architectures. However, it is challenging to directly extend existing NAS methods to attention networks because of the uniform structure of the search space and the lack of long-range feature extraction. To address these issues, we construct a hierarchical search space that allows various attention operations to be adopted for different layers of a network. To reduce the complexity of the search, a low-cost search space compression method is proposed to automatically remove the unpromising candidate operations for each layer. Furthermore, we propose a novel search strategy combining a self-supervised search with a supervised one to simultaneously capture long-range and short-range dependencies. To verify the effectiveness of the proposed methods, we conduct extensive experiments on various learning tasks, including image classification , fine-grained image recognition, and zero-shot image retrieval . The empirical results show strong evidence that our method is capable of discovering high-performance full-attention architectures while guaranteeing the required search efficiency.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
