### Graph Embedding
From Section 4, several problems should be solved in the future. The categories of neuromuscular and structural diseases will be further subdivided, and a multi-class experiment will be discussed. Furthermore, the problem where the minority class was classified as the majority class due to the sample imbalance will be studied in further work.
