A brief introduction to this code: (change 6000 to 4800)
- STC-CVCNN_Train: train feature embedding on auxiliary dataset of 90 classes, and visualization based on test dataset of 10 classes
- STC-CVCNN_Test: train LR classifer with few-shot training dataset (1-5-10-15-20 shots), and test it on test dataset. Here, this code executes 100 times, because different few-shot training datasets have different performance.
- STC-CVCNN_SC: feature visualization & get silhouette coefficient
