A Domain-Adapted Machine Learning Approach for Visual Evaluation and Interpretation of Robot-Assisted Surgery Skills
Bibliographic record
Abstract
In this study, we present an intuitive machine learning-based approach to evaluate and interpret surgical skills level of a participant working with robotic platforms. The proposed method is domain-adapted, i.e., jointly utilizes an end-to-end learning approach for smoothness detection and domain knowledge-based metrics such as fluidity and economy of motion for extracting skills-related features within a given trajectory. An advantage of our approach compared to similar stochastic or deep learning models is its intuitive and transparent manner for extraction and visualization of skills-related features within the data. We illustrate the performance of our proposed method on trials of the JIGSAWS data set as well as our own experimental data gathered from Phantom Premium$\boldsymbol{1.5}$A Haptic Device. This approach utilized$\boldsymbol{t}\text{-}{\mathbf {SNE}}$technique and provides visualized low-dimensional representation for different trials that highlights nuanced information within the executive task and returns unusual or faulty trials as outliers far away from their normal skill or participant clusters. This information regarding the input trajectory can be used for evaluation and education applications such as learning curve analysis in surgical assessment and training programs.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
