Abstract

fetched live from OpenAlex

Delineation of satellite streaks in astronomical images is an important aspect of ground based space studies. While deep learning algorithms show promise, training and validation of deep learning models for satellite streak segmentation is challenging due to the limited availability of large-scale, annotated datasets. We introduce SatStreaks, a dataset comprising of 3,130 densely annotated, real images of satellite streaks captured through ongoing citizen science projects. We utilize SatStreaks to develop a U-Net based model for the streak segmentation and conduct an experimental evaluation of data-driven image segmentation algorithms. The satellite streak segmentation codebase consisting of various deep learning models, and the SatStreak dataset has been made publicly available (https://github.com/jijup/SatStreaks <https://github.com/jijup/SatStreaks> ) to facilitate the advancement of computer vision algorithms for space studies.

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.
