Shared Space Transfer Learning for analyzing multi-site fMRI data

no code implementations NeurIPS 2020 Muhammad Yousefnezhad, Alessandro Selvitella, Daoqiang Zhang, Andrew J. Greenshaw, Russell Greiner

The optimization procedure extracts the common features for each site by using a single-iteration algorithm and maps these site-specific common features to the site-independent shared space.

Deep Representational Similarity Learning for analyzing neural signatures in task-based fMRI dataset

no code implementations28 Sep 2020 Muhammad Yousefnezhad, Jeffrey Sawalha, Alessandro Selvitella, Daoqiang Zhang

This paper develops Deep Representational Similarity Learning (DRSL), a deep extension of RSA that is appropriate for analyzing similarities between various cognitive tasks in fMRI datasets with a large number of subjects, and high-dimensionality -- such as whole-brain images.

Supervised Hyperalignment for multi-subject fMRI data alignment

no code implementations9 Jan 2020 Muhammad Yousefnezhad, Alessandro Selvitella, Liangxiu Han, Daoqiang Zhang

This paper proposes a Supervised Hyperalignment (SHA) method to ensure better functional alignment for MVP analysis, where the proposed method provides a supervised shared space that can maximize the correlation among the stimuli belonging to the same category and minimize the correlation between distinct categories of stimuli.
