Description

The objective of handwritten mathematical expression clustering problem is to group the handwritten math expression patterns into groups of similar ones. By this way, the user can perform an action on a group of similar patterns. This is useful for the marking problem since the teacher can mark and give feedback efficiently.

Protocol

We use the purity and the marking cost function presented in the following paper to evaluate the methods.

V. T. M. Khuong, H. Q. Ung, C. T. Nguyen, and M. Nakagawa, "Clustering Offline Handwritten Mathematical Answers for Computer-Assisted Marking," Proc. 1st International Conference on Pattern Recognition and Artificial Intelligence, pp. 121-126, Montreal, Canada, 2018.
