New neuro theory manuscript up on bioRxiv titled "Constrained brain volume in an efficient coding model explains the fraction of excitatory and inhibitory neurons in sensory cortices". With @INemenman and led by Arish Alreja. Take a look and RT!

TL;DR Mammalian brains vary in size by orders of magnitude. But the ratio of excitatory to inhibitory cells in their sensory cortexes varies by only a factor of 3. In a new preprint, we explain why this could be. Read below to find out.

New paper just accepted at IEEE Transactions in Computational Imaging titled "Parallel Unbalanced Optimal Transport Regularization for Large-scale Imaging Problems" with @John07252731 and Nick Bertrand (not on twitter): arxiv.org/pdf/1909.00149…

ML (and maybe neuro) folks, we're excited about a new ICML paper: "Active Embedding Search via Noisy Paired Comparisons" by Canal (@GregHCanal), Massimino, Davenport and Rozell. What's the summary? Glad you asked.
Preprint: arxiv.org/pdf/1905.04363
Code: github.com/siplab-gt/pair…
The problem we're considering is "preference search", which is the task of finding the best "item" for a given user. An "item" is just a vector in a vector space, so this is a very general formulation that could have many applications.

@resolvingdust @sbarolo I agree that the attention need to be turned to those women. My question is, for a man who is (wrongly) focused on the potential for false accusations, what ways are there to get him focused on the right things (the victims)?
@resolvingdust @sbarolo These guys are real people that are causing real damage in their organizations by this attitude. Getting them to leave the twitter conversation doesn't change the damage they are doing there.

@resolvingdust @j_zelikova@sbarolo@John7Istheman@McLNeuro@james_t_webber So my shorthand to try and communicate the idea on twitter is obviously conveying something I didn't intend. I'm sorry. I was trying to say we share similar goals.
@resolvingdust @j_zelikova@sbarolo@John7Istheman@McLNeuro@james_t_webber My hope is that women would face fewer instances of harassment in the institutions, organizations and communities where they engage in STEM careers.

We often want to understand a complex dynamical system (e.g., climate) by collecting measurements over time of a relevant quantity /1
(e.g., carbon dioxide concentration). Previous (amazing) results showed that this time series can be used to create an image of the /2

Neuro/phys/math twitter, check out our new paper in Phys Rev E. How much information does a time series measurement contain about a dynamical system? New fundamental observability results for nonlinear systems. Ten years of work to get this paper finished! goo.gl/9J4sBZ@SuryaGanguli@gordonberman@INemenman@jaschasd , you all are card carrying physicists and may especially enjoy this.
