If you analyse time-resolved data (M/EEG, iEEG, pupillometry, force recordings…) and feel limited by cluster-based permutation tests (CBPTs); especially when trying to determine when an effect starts or ends; you may want to try our new R package:

Modelling time-resolved electrophysiological data with Bayesian generalised additive multilevel models
Providing utility functions for fitting Bayesian generalised additive multilevel models (BGAMMs) to time-resolved data (e.g., M/EEG, pupillometry, mouse-tracking, etc) and identifying clusters.

Prediction: task-based optimization will ultimately prove to have a relatively minor role in DNN models of the ventral stream. Although tasks (including self-supervised ones) are currently crucial, there are signs that a simpler approach is possible. A thread:

This essay is worth reading. Discusses diminishing returns (and risks) of scaling. The contrast between West and East: “Winner takes all” approach of building the biggest thing vs a long-term focus on practicality.

Y’all are reading this paper in the wrong way. We love to trash dominant hypothesis, but we need to look for evidence against the manifold hypothesis elsewhere: This elegant work doesn't show neural dynamics are high D, nor that we should stop using PCA It’s quite the opposite! (thread)

Noise ceilings are really useful: You can estimate the reliability of your data and get an index of how well your model can possibly perform given the noise in the data. But, contrary to what you may think, noise ceilings do not provide an absolute index of data quality. Let's dive into why. 🧵

I think “Academia = papers” vs. “Science = helping society” is too simplistic. Science isn’t always about direct utility; sometimes its value is understanding itself. And academia isn’t defined by papers — that’s just the current incentive system.

From ancient Greece to the Arabic golden age, scholars have been driven by their curiosity to investigate astronomy, history, philosophy, and sundry other disciplines. Is there a structure to that curiosity? Are astronomers as likely to also be historians or to also be philosophers?

I wanted to add some thoughts to this excellent blog post, not detailed, maybe wrong, maybe useful: 1. Unique variance is easy to interpret as a lower bound of what a variable explains (the upper bound being either what the variable explains alone or what the other variables cannot explain uniquely)
