Deep neural network with weight sparsity control and pre-training extracts hierarchical features and enhances classification performance: Evidence from whole-brain resting-state functional connectivity patterns of schizophrenia.
TL;DR: The proposed schemes and reported findings attained by using the DNN classifier and whole-brain FC data suggest that such approaches show improved ability to learn hidden patterns in brain imaging data, which may be useful for developing diagnostic tools for SZ and other neuropsychiatric disorders and identifying associated aberrant FC patterns.

Method and apparatus to encode and/or decode signal using bandwidth extension technology
TL;DR: In this paper, a method and apparatus to perform bandwidth extension encoding and decoding encodes and/or decodes a high frequency signal using an excitation signal for a low frequency signal encoded in a time domain or a frequency domain.
Journal ArticleDOI
Hippocampus–precuneus functional connectivity as an early sign of Alzheimer's disease: A preliminary study using structural and functional magnetic resonance imaging data
TL;DR: The effect sizes of these aberrant FC levels associated with AD were greater than that of cortical atrophy levels when comparing using normalized Z score and Cohen's d measures, which indicates that an aberrantFC level may precede cortex atrophy.
Journal ArticleDOI
Real-time fMRI-based neurofeedback reinforces causality of attention networks.
TL;DR: In participants who received the feedback of attention-related neuronal activity, the EC estimated from Granger causality analysis was reinforced within the task-related network, such as between the bilateral cingulate gyri and frontal cortices, whereas the EC between the tasks and task-unrelated resting-state network was diminished.
Patent
Method and apparatus to determine encoding mode of audio signal and method and apparatus to encode and/or decode audio signal using the encoding mode determination method and apparatus
TL;DR: In this article, a mode determination threshold for the current frame is adaptively adjusted according to a long-term feature of the audio signal for a frame (the current frame) that is subject to encoding mode determination.
