Discovering the neural correlate informed nosological relation among multiple neuropsychiatric disorders through dual utilisation of diagnostic information

no code implementations29 Sep 2021 Wenjun Bai, Tomoki Tokuda, Okito Yamashita, Junichiro Yoshimoto

The unravelled nosological relation among diverse types of neuropsychiatric disorders serves as an important precursor in advocating the dimensional approach to psychiatric classification.

Improving the spectral resolution of fMRI signals through the temporal de-correlation approach

no code implementations NeurIPS Workshop AI4Scien 2021 Wenjun Bai, Junichiro Yoshimoto

The inherent infra-slow, narrowband signal thwarts the fMRI modality in considering as an optimal neuroimaging modality to its alternatives, e. g., EEG and MEG, in investigating the spectral character of cortical activities.

Multiple-view clustering for identifying subject clusters and brain sub-networks using functional connectivity matrices without vectorization

no code implementations20 Oct 2020 Tomoki Tokuda, Okito Yamashita, Junichiro Yoshimoto

However, when one applies an existing multiple-view clustering method to fMRI data, there is a need to simplify the data structure, independently dealing with elements in a FC matrix, i. e., vectorizing a correlation matrix.

A Generalized Natural Actor-Critic Algorithm

no code implementations NeurIPS 2009 Tetsuro Morimura, Eiji Uchibe, Junichiro Yoshimoto, Kenji Doya

In this paper, we describe a generalized Natural Gradient (gNG) by linearly interpolating the two FIMs and propose an efficient implementation for the gNG learning based on a theory of the estimating function, generalized Natural Actor-Critic (gNAC).
