A Deep-Learning Approach for Task Recognition of Industrial Workers and RULA Score Calculation
Bibliographic record
Abstract
Human activity has been closely related to the development of musculoskeletal disorders. Workers in industries such as manufacturing, assembly, and construction often engage in repetitive and various motions, such as lifting heavy objects or performing the same task for a long period. Because such activities can increase the risk of various muscular disorders, it is important to help workers choose the best postures when performing their activities. In this study, we propose a deep learning approach for task recognition and RULA score calculation. Our approach uses a revised version of the Long Term Recurrent Convolutional Neural network-based model to classify work activities based on video input and then applies a separate neural network to estimate the RULA score for each input activity. We trained and evaluated our approach using a dataset of annotated work activities. Our results show that our approach achieves competitive accuracy for activity recognition and RULA score estimation, demonstrating the potential of deep learning for improving ergonomic assessments in the workplace.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
