Uh, where, where do current AI models for protein engineering fall short without high quality experimental data sets?

David YoungerGUEST
I think one of the key places where you'll see that they fall short is generalizability.

David YoungerGUEST
So often you'll have models that are, you know, trained on a particular data set, and they're good at solving problems kind of local to that data set.

David YoungerGUEST
Um, so for example, a model that's trained on the PDB is going to understand how to design protein structures and, and potentially binders, uh, with proteins that look a lot like those proteins that they see in the PDB, uh, but not necessarily be able to extrapolate beyond those kind of relatively small, relatively, uh, uh, uh, you know, less, less diverse sets.

David YoungerGUEST
Um, so I think that that's one problem, right, is, is lack of generalizability.

David YoungerGUEST
Uh, another major problem with publicly available data in particular is the lack of negative data.

David YoungerGUEST
Uh, so obviously the PDB contains the structures of true interactions between proteins.

And how do you think about monetizing data through, through licensing, partnerships, subscriptions, or other models?
