Adaptive sparseness for correntropy-based robust regression via automatic relevance determination

no code implementations31 Jan 2023 Yuanhao Li, Badong Chen, Okito Yamashita, Natsue Yoshimura, Yasuharu Koike

In the present study, regarding the maximum correntropy criterion (MCC) based robust regression algorithm, we investigate to integrate the MCC method with the automatic relevance determination (ARD) technique in a Bayesian framework, so that MCC-based robust regression could be implemented with adaptive sparseness.

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.

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.
