Critique 2

The article reads really well with all aspects being covered. I had a few minor points,

• Can you rephrase this line, “two high-dimensional cell datasets in a lower but still high-dimensional latent space” because its not clear if the latent space is lower or higher.
• Results do not include Adjusted Rand Index (ARI), Normalized Mutual Information (NMI) and Adjusted Mutual Information (AMI) for evaluation
• Zoom out/increase the size of the clustering figures, it is a bit difficult to see the legend.
