Longitudinal study of early mild cognitive impairment via similarity-constrained group learning and self-attention based SBi-LSTM

作者:

Highlights:

• We devise a similarity-constrained group sparse network (SGN) for multi-center brain functional connectivity network (BFCN) construction, which can learn the similarity among features and reduce the useless features simultaneously.

• We design a SBi-LSTM framework to utilize the longitudinal information for EMCI detection.

• We explore a self-attention mechanism to find the most discriminative features to improve the detection performance.
