Spiral Contrastive Learning: An Efficient 3D Representation Learning Method for Unannotated CT Lesions

no code implementations23 Aug 2022 Penghua Zhai, Enwei Zhu, Baolian Qi, Xin Wei, Jinpeng Li

In the past five years, several works have tailored for unsupervised representations of CT lesions via two-dimensional (2D) and three-dimensional (3D) self-supervised learning (SSL) algorithms.

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.
