Abstract

fetched live from OpenAlex

The information extraction of high-resolution remote sensing images is an increasingly important part in essential urban planning, geological survey, and disaster monitoring. High-resolution feature information helps us quickly understand the arrangement of ground targets in an area. This article proposes a model called MDAUNet with multi-dimensional attention module, based on different dimensional information of road feature maps for attention. Besides, we use a variable size convolution group (VCG) module in resnet embedded to obtain better road representation. At the same time, to obtain road feature information at different levels in the decoding part, we adopt the dense connection of the decoding part to optimize the feature map of the decoding part. Our proposed road multi-dimensional information attention network has achieved superior performance on the Ottawa road dataset and CHN-CUG road dataset, its performance far exceeds the national art level.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
