Sample-Efficient Online Control Policy Learning with Real-Time Recursive Model Updates
Data-driven control methods need to be sample-efficient and lightweight, especially when data acquisition and computational resources are limited -- such as during learning on hardware. Most modern data-driven methods require large datasets and struggle with real-time updates of models, limiting their performance in dynamic environments. Koopman theory formally represents nonlinear systems as linear models over observables, and Koopman representations can be determined from data in an optimizat…

It’s interesting to see where browsers tap out when counting stuff.
When I was testing heading levels, I found Firefox & Safari go to 2,147,483,647 while Chromium only goes up to 9.

Active Learning and Explainable AI for Multi-Objective Optimization of Spin Coated Polymers
Spin coating polymer thin films to achieve specific mechanical properties is inherently a multi-objective optimization problem. We present a framework that integrates an active Pareto front learning algorithm (PyePAL) with visualization and explainable AI techniques to optimize processing parameters. PyePAL uses Gaussian process models to predict objective values (hardness and elasticity) from the design variables (spin speed, dilution, and polymer mixture), guiding the adaptive selection of sa…

People have lots of reasons for loving human languages. Some find that they sound romantic, others love the ways that they can be patterned into poetry or song, and still others find them fascinating in the ways that they morph and change over time.
Me? The thing I love most about the English language is how easy it is to accidentally write "pubic" when you meant "public", and vice-versa.

High resolution mapping of molecular tori with ALMA
Recent high resolution mapping of the circum-nuclear regions of Active Galactic Nuclei (AGN) has revealed the existence of geometrically thin nuclear disks, in general randomly oriented with respect to their galaxy hosts. These molecular tori have typical radii of 10~pc, and contain a few 10$^7$ M$_\odot$ of H$_2$, with H$_2$ column densities between 10$^{23}$ and 10$^{25}$ cm$^{-2}$. We mapped two of the most massive of these molecular tori with higher resolution, in order to unveil their morp…

Senator Murphy:
It’s pretty wild that the corruption is so brazen, is so transparent.
Vought sent out this tweet yesterday saying, I’m canceling energy projects in the following states, and listed the states.
And every single one of them is a state represented by two Democratic senators.
And the one Democratic senator who voted for the Republican continuing resolution
—that senator’s state wasn’t on the list.
So, you know, it’s just there for everybody to s…

Transcript: Chris Murphy’s Dark and Unnerving New Warning about Trump
The Democratic Senator has taken the lead in drawing attention to Trump’s authoritarianism. In an interview, he offers a stark new warning that should galvanize his fellow Democrats before it’s too late.

NEO: No-Optimization Test-Time Adaptation through Latent Re-Centering
Test-Time Adaptation (TTA) methods are often computationally expensive, require a large amount of data for effective adaptation, or are brittle to hyperparameters. Based on a theoretical foundation of the geometry of the latent space, we are able to significantly improve the alignment between source and distribution-shifted samples by re-centering target data embeddings at the origin. This insight motivates NEO -- a hyperparameter-free fully TTA method, that adds no significant compute compared…

If lepers were socially excluded and removed from the community of the visible church, their existence still made God manifest, as they showed both his anger and his bounty: ‘Dearly beloved’, says a ritual from a church in Vienne in the south of France, ‘it has pleased God to afflict you with this disease, and the Lord is gracious for bringing punishment upon you for the evil that you have done in this world.’ The leper was then dragged out of the church by the priest and his acolytes gressu retrogrado but he was assured that he was God’s witness: ‘however removed from the church and the company of the saints, you are never separated from the grace of God’. Brueghel’s lepers watch from afar, but forever, as Christ climbs Mount Calvary accompanied by a whole people. Hieratic witnesses of evil, their salvation is assured by their exclusion: in a strange reversal quite opposed to merit and prayers, they are saved by the hand that is not offered. The sinner who abandons the leper to his fate thereby opens the door to his salvation. ‘Thus be patient in your sickness, for the Lord does not underestimate your ills, nor separate you from his company. If you have patience, so shall you be saved, like the leper who died outside the door of the rich man, and was carried straight up to Heaven.’ Abandonment is his salvation, and exclusion offers an unusual form of communion.
