Another very useful trick I learned for handling criticism, especially when you're standing nervously on stage and the critic is being unfriendly, unreasonable, and unlikely to change their mind about anything: If you don't feel y

I love Markdown. I'm a bit surprised, though, that you still can't open a .md file by default in most web browsers. It seems like it should be quite trivial to have the browser automatically convert it to html and display it.

Computing entropies of high-dimensional random vectors for a theoretical neuroscience study. The journey is mostly a repetition of (1) almost giving up because it's completely hopeless, (2) taking a hot shower, (3) realizing there migh

A notable and interesting point of this article is that convolutions and correlations (convolutions without flipping the filter) are quite a bit more subtle on the sphere than on Cartesian spaces. For a convolution between a function and a

Thanks for the link to your article! If you don't mind my asking, how much does the role of mutual information in linking logical and thermodynamic reversibility depend on considering quantum systems? I.e. does your footnote 37, which

There are a few folks working on this in neuroscience, e.g. training transformers to "decode" neural activity ( https://arxiv.org/abs/2310.16046 ). It's still pretty new and a bit unclear what the most pro

This reminds me of a project I worked on during my PhD, where you create a network of scientific documents and notes/threads via Markdown, with a similarly structured "rabbit-hole" linking system: https://github.co

Yep! This relationship is well known in statistical mechanics. I was just surprised that in many years of intersecting with information theory in other fields (computational neuroscience in particular) I'd never come across it before,

Connectome-adjacent neuroscientist here. Definitely not a dead end! But also definitely not the whole picture. One of the main open questions in neuroscience right now is how network structure, dynamics, and function are related in the brai

I love that Ridge Regression is introduced in the context of multicollinearity. It seems almost everyone these days learns about it as a regularization technique to prevent overfitting, but one of its fundamental use cases (and indeed its o

I had the same thought. If a were constant I believe the solution would just be a convolution of b_t with an exponential filter. I think this is different because a_t depends on time, so it's equivalent to convolving b_t with a filter
