The invention relates to the technical field of trajectory accompanying, in particular to a
schizophrenia prediction model construction method based on multi-
modal subject data and
artificial intelligence, which comprises the following steps: standardizing a prospective
queue design and a multi-
modal data acquisition protocol; carrying out synchronous acquisition and
quality control on multi-
modal data; carrying out dimension reduction and cross-modal alignment fusion
processing on the data; and combining an improved
loss function and a self-
adaptive optimization algorithm to
train the model, and performing
verification and iterative optimization. According to the
schizophrenia prediction model construction method based on the multi-modal subject data and the
artificial intelligence, multi-modal standardized acquisition is taken as a core, multi-dimensional
pathological support is provided for prediction through multi-
modal data deep coverage and standardized acquisition, and refined preprocessing is designed for different modals, so that the
schizophrenia prediction model construction efficiency is improved. In combination with modal specific
feature extraction and cross-modal alignment fusion, a dynamic weighted multi-modal network is matched with multi-
task learning and improved AdamW optimization, and in combination with comparison pre-training, characterization capability and training efficiency are improved.
