Could you tell me how you use T-SNE? Thank you!
Hi, T-SNE plots (in Figure 4) are obtained as follow:
-
Training the network with the desired method under the target imbalanced ratio, e.g., M2m with \rho=100
-
Then, randomly select N training samples per class which will be plotted using T-SNE. (E.g., N=50 in the paper)
-
Obtaining the "penultimate features", i.e., before the linear classifier, of the selected samples using the trained network
-
The, plot the obtained features using any T-SNE code, e.g., Multicore-TSNE (https://github.com/DmitryUlyanov/Multicore-TSNE)
Best,
Jaehyung
