Predictive Coding with Bayesian Priors via Proximal Gradients
We recast predictive coding as continuous-time proximal gradient descent applied to a regularized maximum-a-posteriori (MAP) objective. We study first a single-level problem and then a multi-level hie...

New paper out in JEP:HPP! psycnet.apa.org/doi/10.1037/... Can we learn from things we're not paying attention to? We used a contextual cueing paradigm to pit selective attention against spatial prediction during visual search in 2 high-powered (N=104) experiments — and found they actively compete.

“The penalty is a 1-year ban from arXiv followed by the requirement that subsequent arXiv submissions must first be accepted at a reputable peer-reviewed venue.“ It’s more intense than a one-year ban. You still can’t post preprints after one year, only papers accepted for publication.

It really is quite grimly hilarious how the drive for "Open Access" in academic publication was almost immediately captured by publishers who declared that, if readers weren't going to pay, then authors and their employers would have to. And we bought it, schmucks.

the cutoff scores for #MSCA postdoc fellowships are very high this year. has the score distribution shifted compared to previous years? I made a plot with scores from past years. if scores are at ceiling level, the process becomes essentially a lottery, because minor issues can lead to deductions.

Chatbots offer a magnificent bribe - a fast, frictionless route to information that bypasses the discomfort of learning.
