Claim 6:
7. The TCM syndrome classification method based on multi-graph attention according to claim 2, wherein the specific step of constructing a symptom-symptom graph, a symptom-syndrome element graph and a symptom embedding matrix in Step 1 comprises:
Step 1-1: constructing a symptom-symptom undirected graph Ss: counting the frequency of all symptoms appearing in clinical data, extracting the symptoms with frequency ≥threshold M, and connecting the symptoms in pairs to form the symptom-symptom undirected graph Ss;
Step 1-2: constructing a symptom-syndrome element undirected graph Se: comparing any two clinical data, counting the number of the same syndrome elements in the two clinical data, and connecting the symptoms of the two clinical data if the number of the same syndrome elements is greater than the threshold N;
Step 1-3: constructing a symptom embedding matrix em={em1, em2, em3, . . . emn}, and defining emi=s={s1, s2, s3, . . . sm}, where n is the total number of clinical data.
