Abstract

fetched live from OpenAlex

Deep image super resolution networks use a nonlinear end-to-end mapping between the low and high resolution versions of an image and therefore, provide a good performance. As the different parts of a single image appear in different scales, developing a deep learning based image super resolution scheme that is capable of generating features at different scales and levels is essential. In this paper, a new residual block is proposed with a view of generating a rich set of features extracted at different scales and levels. The development of the proposed block is carried out using two distinct strategies, the first one focussing on generating features directly in two different scales, whereas the second one aims at generating multi-scale features indirectly by extracting them from two different hierarchical levels of abstraction. It is shown through experimental results that the proposed scheme of designing the residual block results in a network that provides a superior performance with reduced number of parameters than that provided by the light-weight networks using other types of residual blocks.

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.
