767 positive instances and 767 negative instances are randomly selected from the LR instance test set, and are used to get feature embedding by our first-stage model. The embeddings are reduced to two dimensions by t-SNE, and the corresponding instances and relative positions are plotted to visualize the feature space. We only show one image in one place in map to avoid overlapping. The color of the frame around the instances indicates the annotation category of them.
