Abstract

fetched live from OpenAlex

Road extraction from optical remote sensing images has many important application scenarios, such as navigation, automatic driving and road network planning, etc. Current deep learning based models have achieved great successes in road extraction. Most deep learning models improve abilities rely on using deeper layers, resulting to the obese of the trained model. Besides, the training of a deep model is also difficult, and may be easy to fall into over fitting. Thus, this paper studies to improve the performance through combining multiple lightweight models. However, in fact multiple isolated lightweight models may perform worse than a deeper and larger model. The reason is that those models are trained isolated. To solve the above problem, we propose an Adaboost-like End-To-End Multiple Lightweight U-Nets model (AEML U-Nets) for road extraction. Our model consists of multiple lightweight U-Net parts. Each output of prior U-Net is as the input of next U-Net. We design our model as multiple-objective optimization problem to jointly train all the U-Nets. The approach is tested on two open datasets (LRSNY and Massachusetts) and Shaoshan dataset. Experimental results prove that our model has better performance compared with other state-of-the-art semantic segmentation methods.

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.
