Can rotation angle information improve accuracy? #22
Description
The current open-set method, based on Maddie's work, uses cluster fill rates. Amy found that using graph rotation angle information in addition to the cluster fill counts improved accuracy for her closed-set method. It's possible that graph rotation angles might also improve the open-set method's accuracy. Rotation angle information could be incorporated in many ways, but here is one idea. For a given document, for each cluster, calculate the mean rotation angle of the graphs assigned to that cluster. Then, the features for the document are a vector consisting of 40 cluster fill rates and 40 mean rotation angles.
