In my Bio-Inspired AI & Optimization course, I scaffold intro to reinforcement learning with earlier content about swarm intelligence (like Ant Colony Optim.). The RL stuff frames the trails as an embodied Q(s,a) function. See 9:13 to 12:40 in video: youtu.be/DPIbp4e5kAo?... 1/🧵

So, I thought it was pretty cool to see this new #SwarmIntelligence article pop up on my feed this morning, from Soma et al. (2026) [including @swarmdynamics.bsky.social]. They take the analogy way further than I ever did! They focus on the honey-bee waggle dance as a single RL agent. 2/🧵
I was impressed how they combined formalism with an awareness of the gaps between the waggle dance model and observed honey-bee behavior (and thus limitations of their inferences). See their work at: * arXiv: doi.org/10.48550/arX... * Swarm Intelligence: doi.org/10.1007/s117... 3/3

New widget for exploring GLMM's or warm-starting #stats coding after quick prototyping: tpavlic.github.io/topic_visual... Import your own data or use sample data sets. Try different response families/random effects. Export to #Rstats code (+MATLAB/Python). Translate classic tests to GLMM.
And if you prefer something similar that focuses on more classical parametric and non-parametric tests of means (one group, two groups, and several groups -- t tests, ANOVA's, etc.), see this "Output Analyzer" I built for my sim course. tpavlic.github.io/asu-simulati...
Update: Latest version can export any analysis shown in the current view to code for #MATLAB, Core&Tidy #Rstats, and #Python. This goes beyond exporting graphs but actually provides code for doing the analyses (including checking for the conditions necessary to meet the assumptions of those tests).
A new widget for my stochastic sim course that might be useful for more general #stats courses -- can act as a web-based replacement for basic JMP. Load data sets at top, do parametric and nonparametric one-sample, two-sample, and multi-comparisons/ANOVA. tpavlic.github.io/asu-simulati...
I haven't maintained my own CV in LaTeX for a while, but I used to have a popular LaTeX CV template that I moved archived to Github some time ago. I had some extra cycles, and so I went and updated it today to support PDF/UA accessible LaTeX. See: github.com/tpavlic/late...
New 🧪 findings show Rosalind Franklin had an earlier X-ray crystallography photo revealing the helical structure of DNA, and her notes about THAT photo showed she recognized it was a helix (and even estimated turn length). Explains why later photograph didn't have notes (and Watson took sole credit)
Exclusive: A new analysis refutes James Watson’s claim that he was the first to recognize the significance of the famed photograph 51. https://scim.ag/4rTKck8

New widget for my stochastic #simulation course that I hope will be useful for other #statistics and #probability courses. Gallery of common probability distributions with info on logical origins, parameters, and how to sample from them among other things. tpavlic.github.io/asu-simulati...

"The whole “Oh no, our models went rogue” thing … When a bridge collapses, you don’t analyze whether the bridge was ethical or sentient or why it decided to collapse. You ask, who is the person who built this bridge to be so flimsy?" www.wired.com/story/one-of...

Last week, my goldendoodle Rosie ate a dead bird, shat feathers, got impacted, and ended up at the vet. But just imagine. She could’ve made history and advanced science.
Another Monte Carlo methods explorer for my simulating stochastic systems course. Demos 6 applications of Monte Carlo methods for estimating output distributions from stochastic models (queueing, inventory, reliability, and more -- 3 dynamic + 3 static). tpavlic.github.io/asu-simulati...

NSF is consolidating its geoscience research grants into a new program, GEOcore and reducing annual grants to $110 million total in 200-350 awards. Typical was about $300 million in 1,200 awards. Not including institutional grants ($1.3 billion/yr) and those may be gone. www.nsf.gov/funding/oppo...
Another concept explorer for my stochastic #simulation course. This widget focuses on what a confidence interval is (tab 1) and then pivots to explaining the 4 major Variance Reduction Techniques in Monte Carlo methods (tabs 2–5). tpavlic.github.io/asu-simulati...
People keep talking about these in Austin, but we also have Tesla Cybercabs driving around Tempe. They're very ugly. In person, the gold looks even worse. abcnews.com/Business/fed...
New widget for my stochastic sim class. This one has three tabs about pseudo random-number generation (LCG, CLCG, MRG) that transition into four tabs about the tournament-based AI #watermarking used in modern LLM's, like Claude and Gemini. Related topics! tpavlic.github.io/asu-simulati...

What luck! Got conditions just right to take this super sharp image of the lunar #eclipse with my 2023 Samsung GS23 Ultra smartphone!
