چکیده

Brain age prediction is important for understanding brain development and aging. Currently, researchers can predict using resting-state functional MRI (rs-fMRI) data. However, there are differences in among different subjects, the same subject also has at ages. So far, how to accurately estimate rs-fMRI efficiently remains a challenging problem. Therefore, model with similarity metric convolutional neural network proposed this paper. Specifically, paper first introduces siamese network, which includes convolution, batch normalization, pooling steps simultaneously learns features of two groups rs-fMRI, designs measurement network. Subsequently, fMRI images subjects input into metirc module designed calculate between images. Then optimized by loss function, finally, average value three sample labels greatest taken. The absolute mean error correlation coefficients obtained from 5.337 0.6279, respectively. Experimental results show that method low high coefficient on longitudinal imaging data set Southwest University.

Brain Age Prediction Based on Resting-State Functional Connectivity Patterns Using Convolutional Neural Networks

Brain age prediction based on neuroimaging data could help characterize both the typical brain development and neuropsychiatric disorders. Pattern recognition models built upon functional connectivity (FC) measures derived from resting state fMRI (rsfMRI) data have been successfully used to predict the brain age. However, most existing studies focus on coarse-grained FC measures between brain r...

Link Prediction using Network Embedding based on Global Similarity

Background: The link prediction issue is one of the most widely used problems in complex network analysis. Link prediction requires knowing the background of previous link connections and combining them with available information. The link prediction local approaches with node structure objectives are fast in case of speed but are not accurate enough. On the other hand, the global link predicti...
