Simulation-based Inference (SBI) brings the power of generative modeling to parameter inference in science and engineering. We have now written a practical guide on how to effectively use these methods across domains 🔭👁️‍🗨️🦞
Simulation-based inference (SBI) has transformed parameter inference across a wide range of domains. To help practitioners get started and make the most of these methods, we joined forces with researchers from many institutions and wrote a practical guide to SBI.

Simulation-Based Inference: A Practical Guide
A central challenge in many areas of science and engineering is to identify model parameters that are consistent with prior knowledge and empirical data. Bayesian inference offers a principled framewo...

It works as we last tried sequences from an unreleased glycoprotein-host receptor complex, and it predicted a positive interaction score!
Our PLM-interact is out in Nature Communications! We show that jointly encoding protein pairs using protein language models improves protein–protein interaction prediction performance and enables fine-tuning to predict mutation effects in human PPIs. www.nature.com/articles/s41...

Ok, I am gonna watch some cat clips to cheer me up...
Can't emphasize how damaging this is. A single non-scientist—Peter Bogner—holds all power & makes all decisions at GISAID & provides no justifications for any of them, except blatantly false ones.

He has that power because he conned rich & powerful people into giving it to him. Enough.
I want to spell this out in case the implications aren't clear:

This means all public tools/webapps of GISAID data (all the ones you've been used to seeing thru the pandemic, as far as we can tell) are prohibited.

The file allowed this. Cut that - cut off all tools the public & others were using.

Later SARS-CoV-2 viruses in humans evolved the ability to use New World monkey ACE2, and recombination seems to be able to sample more mutations for the spike gene to cross species barriers.

Wild story. Global spread of African Swine Flu is said to be depriving Amur tigers of their wild boar prey in remote Siberia. The swine flu link looks conjectural but plausible in this account.
Another case of panzootic consequences?

As expected, unfortunately.

If ever you needed a reason for never using GISAID ever again (as a data producer or data user - we're both), look no further.

Time to move on to more trusted and transparent solutions.
