Conformal Isometry of Lie Group Representation in Recurrent Network of Grid Cells

1 code implementation6 Oct 2022 Dehong Xu, Ruiqi Gao, Wen-Hao Zhang, Xue-Xin Wei, Ying Nian Wu

Recurrent neural networks have been proposed to explain the properties of the grid cells by updating the neural activity vector based on the velocity input of the animal.

GenSample: A Genetic Algorithm for Oversampling in Imbalanced Datasets

no code implementations23 Oct 2019 Vishwa Karia, Wen-Hao Zhang, Arash Naeim, Ramin Ramezani

In this paper, we present a novel technique based on genetic algorithms, GenSample, for oversampling the minority class in imbalanced datasets.

Bimodular continuous attractor neural networks with static and moving stimuli

no code implementations16 Oct 2019 Min Yan, Wen-Hao Zhang, He Wang, K. Y. Michael Wong

We found that when bumps coexist in both modules, the position of each bump is shifted towards the other input when the intermodular couplings are excitatory and is shifted away when inhibitory.

Exploiting the Value of the Center-dark Channel Prior for Salient Object Detection

no code implementations14 May 2018 Chunbiao Zhu, Wen-Hao Zhang, Thomas H. Li, Ge Li

In this paper, we propose a novel salient object detection algorithm for RGB-D images using center-dark channel priors.

“Congruent” and “Opposite” Neurons: Sisters for Multisensory Integration and Segregation

no code implementations NeurIPS 2016 Wen-Hao Zhang, He Wang, K. Y. Michael Wong, Si Wu

Mimicking the experimental protocol, our model reproduces the characteristics of congruent and opposite neurons, and demonstrates that in each module, the sisters of congruent and opposite neurons can jointly achieve optimal multisensory information integration and segregation.

Reciprocally Coupled Local Estimators Implement Bayesian Information Integration Distributively

no code implementations NeurIPS 2013 Wen-Hao Zhang, Si Wu

Psychophysical experiments have demonstrated that the brain integrates information from multiple sensory cues in a near Bayesian optimal manner.
