The application provides a depression onset risk prediction method and
system based on causal representation learning, and relates to the technical field of intelligent
medical treatment. First, a multi-source implicit
monitoring data set of a target object is obtained, which includes autonomic nervous function nonlinear micro features, intelligent terminal touch behavior micro features, environmental spatio-temporal
big data, and non-depression related medical track data in an electronic health
record. Then, the
data set is subjected to causal variable level marking
processing. Next, a causal variational
autoencoder network is called to extract a causal latent representation vector set. Then, a
causal link graph model is constructed based on the causal latent representation vector set and the causal variable level marking. Finally, causal weighted fusion
processing is performed on real-time collected individual multi-source
time series monitoring data according to the
causal link graph model, and the depression super-
early onset risk assessment model is input to generate a depression onset
risk probability output result containing a prediction time window identifier. The application realizes super-early accurate prediction of the depression onset risk.
