Time to retire this account. It will stay up but I won't post and probably won't check it, either. I'll be hanging out at @rapodaca@fosstodon.org for now instead. The posts at depth-first.com will continue.

What are the hardest problems right now in drug discovery? Has deep learning had any effect?

IMO, goal should be to ↓ bad interpretations, not "bad data." Readers should expect authors to provide the data needed to do that. How much & what kind depends on situation. Bigger problem is how hard it is to turn this into editorial policy.

Something I've wanted to write for a while—my argument for why journals shouldn't require 13C NMR for publication. (This post was inspired by the many long hours I've spent collecting 13C NMR spectra.) Hear me out! corinwagen.github.io/public/blog/20…

Any time it involves tautomers, you're in for a ride.

When it comes to organic synthesis, ChatGPT may be kind of book smart, but it's not very street smart.

Here it confuses Oc1ccccc1 with benzene in the text, then proceeds to include the oxygen atom in the molfile, modulo one carbon, but with a complete connection table for the underlying graph, modulo one carbon, but with correct placement for oxygen.

🤣 My tinkering so far reveals that ChatGPT readily recognizes SMILES, always confidently decodes them, doesn't appear to be doing simple string matching, and has a ~50:50 average for simple cases. I'm still blown away that this is a thing.

@cthoyt No, but I've poked around at it. It's interesting, but there's also a lot of centralization potential there that isn't recognized now because users are scarce. I'm not sure many people realize this.

@Dereklowe @OrdoSeclorum 1. No RSS auto-discover link (could trip up some readers) 2. Footer links to a page which links to science.org/blogs/pipeline… . 3. My reader (RssBook) sorts feed in _ascending_ chron. order (other feeds are reverse). 4. Feed title ("AAAS: Keyword...") is confusing.

Endgame: robotic journals vacuum up the best papers from preprint servers, running circles around human editorial boards and reviewers for quality control, fraud detection, and relevance filtering.

@rapodaca One approach of accounting for different tautomers is using data augmentation to train a model to predict the same experimentally observed value for all tautomers (tautomer invariance): nature.com/articles/s4200… → for inference, it doesn't matter if you choose the "right" tautomer

How do machine learning studies account for tautomerism? Not predicting the most stable tautomer and the like, but rather signaling that a molecular comes in tautomeric forms, and where?
