ART-Point: Improving Rotation Robustness of Point Cloud Classifiers …
Point cloud classifiers with rotation robustness have been widely discussed in the 3D deep learning community. Most proposed methods either use rotation invariant descriptors as inputs or try to design rotation equivariant networks. However, robust models generated by these methods have limited performance under clean aligned datasets due to …
Customer churn prediction for telecommunication
Ensemble classifiers have received increasing attention for attaining the higher classification performance in recent times. In this paper, we present comparative performances of various tree based ensemble classifiers in collaboration with maximum relevancy and minimum redundancy (mRMR), Fisher's ratio and F-score based features …

Spiral Staircase Calculator
This angle of rotation varies depending on the situation of the two floors. Let's say we're facing north when we step on the stair landing on the second floor, and we also want to be facing north as we take the first step from the first floor. Then we should use a spiral angle of 360° for that spiral staircase with one full turn, 720° for two ...
