Real-time automatic polyp detection in colonoscopy using feature enhancement module and spatiotemporal similarity correlation unit

no code implementations25 Jan 2022 Jianwei Xu, Ran Zhao, Yizhou Yu, Qingwei Zhang, Xianzhang Bian, Jun Wang, Zhizheng Ge, Dahong Qian

In order to solve these problems, our method combines the two-dimensional (2-D) CNN-based real-time object detector network with spatiotemporal information.

Some Developments in Clustering Analysis on Stochastic Processes

no code implementations5 Aug 2019 Qidi Peng, Nan Rao, Ran Zhao

We review some developments on clustering stochastic processes and come with the conclusion that asymptotically consistent clustering algorithms can be obtained when the processes are ergodic and the dissimilarity measure satisfies the triangle inequality.


Cluster Analysis on Locally Asymptotically Self-similar Processes with Known Number of Clusters

2 code implementations13 Apr 2018 Qidi Peng, Nan Rao, Ran Zhao

We conduct cluster analysis on a class of locally asymptotically self-similar stochastic processes, which includes multifractional Brownian motion as a representative.


Covariance-based Dissimilarity Measures Applied to Clustering Wide-sense Stationary Ergodic Processes

1 code implementation27 Jan 2018 Qidi Peng, Nan Rao, Ran Zhao

We introduce a new unsupervised learning problem: clustering wide-sense stationary ergodic stochastic processes.


Learning Discourse-level Diversity for Neural Dialog Models using Conditional Variational Autoencoders

1 code implementation ACL 2017 Tiancheng Zhao, Ran Zhao, Maxine Eskenazi

While recent neural encoder-decoder models have shown great promise in modeling open-domain conversations, they often generate dull and generic responses.
