Stoked for this work to be out!
Complex systems often display long-range correlations. There is a notion of fine/coarse-graining in a spatial setting through hierarchical tensor networks to capture the relevant physics--but what about temporally?

New preprint!
This is the last chapter for my PhD dissertation to see the light of day: I wrote it to be an accessible introduction to information theory explicitly written for the aspiring complex systems scientist. 1/n

Reaction-diffusions are nonlinear PDEs which describe the formation of a surprisingly rich family of patterns. Introduced by Alan Turing in 1952. en.wikipedia.org/wiki/Reacti… dna.caltech.edu/courses/cs19…

The single most undervalued fact of linear algebra: matrices are graphs, and graphs are matrices.
Encoding matrices as graphs is a cheat code, making complex behavior simple to study.
Let me show you how!

The single biggest argument about statistics: is probability frequentist or Bayesian?
It's both, and I'll explain why.
Buckle up. Deep-dive thread below.

Quantum error mitigation (EM), a technique to correct quantum errors in (mostly) classical post-processing, is seen as a near-term waypoint towards the lofty goal of an error-corrected quantum computer. We point out limitations to how much EM can help.

🚨New preprint!🚨
This is a shorter piece that came out of a side-project I've been working on off and on on the link between information theory and emergence. 1/N

How to move from association to causal representations of brain function🧠? Here we exploit the asymmetry of the passage of time, aka the arrow-of-time, to identify the causal structure underlying brain function. Fantastic work by @ThomasAWBolton1 & team👉biorxiv.org/content/10.1101/…

Matrix factorizations are the pinnacle results of linear algebra.
From theory to applications, they are behind many theorems, algorithms, methods. However, it is easy to get lost in the vast jungle of decompositions.
This is how to make sense of them.

If you did some quantum info research, you have probably heard about semidefinite programs (SDPs). I recently started to use them and wanted to share with you what I learned so far!

Do you use Pearson correlation? Dynamic time warping? Granger causality? Any of the other hundreds of methods for measuring relationships between two time series? In new work, we show how each relate to one another, and can be combined to address scientific problems
New preprint! @olivercliff w/ @NaoTsuchiya @jlizier: "Unifying Pairwise Interactions in Complex Dynamics". Want to quantify the relationship between two time series? We compared over 249 pairwise dependence measures on >1000 multivariate time series 😮

The recording of last week's SNAC seminar from @RobMuNu - "Inferring informational structures in neural recordings of drosophila with epsilon-machines" - is now posted on our YouTube channel - youtu.be/piVM_se3Upg - enjoy!

New preprint by Roberto! In this exciting work, he has shown that quantum dots have a surprising amount of memory that can be detected by watching their luminescence. @modikk @RobMuNu @PaulM_ACEx @excitonscience arxiv.org/abs/2106.12179
