Abstract

fetched live from OpenAlex

Computer vision can be used in robotic exoskeleton control to improve transitions between locomotion modes through the prediction of future environmental states. We developed StairNet to focus specifically on stair recognition due to the potential safety implications and the theoretical risk of injury resulting from environmental misclassification during stair ascent. The dataset was developed using the “ExoNet” database – the largest and most diverse open-source dataset of wearable camera images of walking environments. StairNet contains 515,452 labelled images from six of the twelve original ExoNet classes. These images were carefully reclassified into four classes which use novel definitions created from a computer vision perspective with the goal of increasing the accuracy of the cutoff points between classes within the dataset. Additionally, the dataset was manually parsed numerous times during annotation to reduce misclassification errors and remove images with large abstractions from the dataset.

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.

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.
