I believe science is much more like art than many scientists are willing to consider. I have a feeling that it would free us to do better science if we embraced this view. I may be mistaken but that's where I am mentally.

a thing I’ve noticed in my time in research: many people really want to believe that Data™ is some sort of magical object that contains objective truth
but the thing is, just like everything else, data is _produced_ via processes and mechanisms that profoundly affect the shape of the data

True story: Sometimes when people talk to me about “synthetic data” i just scream “WHERE DO THE BITS OF INFORMATION COME FROM” at them

Every one of Tiago’s papers is a masterpiece. Give it a read if you work with networks constructed from different types of observations!
🚨 New paper on ArXiv:
“Uncertainty quantification and posterior sampling for network reconstruction”
TL;DR; We present an efficient method to sample the entire ensemble of possible network reconstructions that are compatible with an indirect observation, e.g. a dynamics.
