Hi @yuval-alaluf , thank you for the amazing work! Regarding the PCA performed in the paper, could you please share more details? For the 5 different images in Fig.9, did you use their corresponding latent codes as a dataset (a dataset with shape [50, 512] or [50, 18, 512] in this case) and performed PCA on the dataset, or you performed PCA on each individual image (5 datasets with shape [10, 512] or [10, 18, 512] in this case), draw individual paths and then put them in the same figure? Please bear with me if I was wrong.

If I recall correctly we performed PCA on all images together. I no longer have the code so I don't recall exactly :)
