Active Cost-aware Labeling of Streaming Data

no code implementations13 Apr 2023 Ting Cai, Kirthevasan Kandasamy

When the labeling cost is $B$, our algorithm, which chooses to label a point if the uncertainty is larger than a time and cost dependent threshold, achieves a worst-case upper bound of $\widetilde{O}(B^{\frac{1}{3}} K^{\frac{1}{3}} T^{\frac{2}{3}})$ on the loss after $T$ rounds.

MVCNet: Multiview Contrastive Network for Unsupervised Representation Learning for 3D CT Lesions

no code implementations17 Aug 2021 Penghua Zhai, Huaiwei Cong, Gangming Zhao, Chaowei Fang, Jinpeng Li, Ting Cai, Huiguang He

To avoid the subjectivity associated with these methods, we propose the MVCNet, a novel unsupervised three dimensional (3D) representation learning method working in a transformation-free manner.
