While we all share our sequencing data freely, image datasets like these are still often kept private.

I am only aware of a single other study on guppy coloration (there are many!) where images are available, and it's also from our lab (Morris et al. 2020).

I hope this can improve in the future!

The relationship between sexual dimorphism and intersex correlation: do models support intuition?
Abstract. The evolution of sexual dimorphism (the difference in average trait values between females and males, SD), is often thought to be constrained by

Yes I personally prefer to use “deep learning” over “AI”. Not much use for LLMs for now (but perhaps for eg meta-analyses in a couple of years?), but transformer architecture may still hold a lot of promise for sequence data.. Time will tell.

And yes, we used unets for segmentation.

Guppies! ;) I didn’t talk about it, but we also use triplet learning to do GWAS on whole patterns: doi.org/10.1038/s415.... There were quite a few posters on neural nets for image analysis and this is a domain where one can be effective with modest sample sizes.

This website seems odd, it assumes MEPs will vote along country blocks, not European or individual parties?
