Is there any quantitative way to compare results of different sentence embeddings?

Hello everybody.

I'll preface this by saying I'm quite the amateur within the field. Basically what I've done is created embeddings of unlabelled sentences, reduced the embeddings dimensions, and plotted them on a scatter plot. I'm only really aiming to visualize, so there is no clustering involved. Essentially I am now wondering if there is a quantitative way to compare the scatter plots I've created?

Thanks in advance.
