Importance of negative sampling in weak label learning

no code implementations23 Sep 2023 Ankit Shah, Fuyu Tang, Zelin Ye, Rita Singh, Bhiksha Raj

Weak-label learning is a challenging task that requires learning from data "bags" containing positive and negative instances, but only the bag labels are known.

CRIN: Rotation-Invariant Point Cloud Analysis and Rotation Estimation via Centrifugal Reference Frame

1 code implementation6 Mar 2023 Yujing Lou, Zelin Ye, Yang You, Nianjuan Jiang, Jiangbo Lu, Weiming Wang, Lizhuang Ma, Cewu Lu

CRIN directly takes the coordinates of points as input and transforms local points into rotation-invariant representations via centrifugal reference frames.

Visualizing Ensemble Predictions of Music Mood

no code implementations14 Dec 2021 Zelin Ye, Min Chen

Music mood classification has been a challenging problem in comparison with other music classification problems (e. g., genre, composer, or period).
