Finding discriminative and interpretable patterns in sequences of surgical activities

作者：

Highlights：

• We propose a method to discover discriminative patterns of surgical practice.

• The method relies on the vector space model (VSM) and tf * idf framework.

• Evaluation is performed on surgery recordings to predict location, experience and ID of surgeons.

• We also propose a visualization technique that can support surgical training.
