It is silly of #WaPo to focus on the 1st part of Trump's quote and present four pics he has supposedly drawn. And their tabloid-y headline doesn't make it any better:
"Trump said he ‘never wrote a picture in my life.’ Here are four."

If we just not talk about bad things, they surely don’t exist!

Fairness Dynamics During Training
We investigate fairness dynamics during Large Language Model (LLM) training to enable the diagnoses of biases and mitigations through training interventions like early stopping; we find that biases can emerge suddenly and do not always follow common performance metrics. We introduce two new metrics to evaluate fairness dynamics holistically during model pre-training: Average Rank and Jensen-Shannon Divergence by Parts. These metrics provide insights into the Pythia models' progression of biases…

Direct Evidence Of Apex Hypha Interactions During Vegetative Growth Of Fungal Thallus Via Comprehensive Network And Trajectory Extraction
The mycelium of a filamentous fungus is a growing, branching network of numerous entangled hyphae exhibiting polarised apical growth. Expansion occurs during the vegetative phase from a single ascospore, driven by the need to explore and occupy surrounding space limiting competitors, enhancing nutrient uptake, and promoting spore dispersal. Radial, rapid, and rectilinear growth combined with frequent branching appears adaptive. However, passive growth without interactions or feedback may produc…

No, the Orioles' problem is not that Camden Yards doesn't have enough electronic cheerleading. https://www.thebaltimorebanner.com/sports/orioles-mlb/oriol…

The Orioles can feel like the away team at Camden Yards. A new team exec is trying to change that.
The club’s new chief marketing officer met with members of the team this season and asked what entertainment factors they’d like to see added during the game.

Global Optimization Algorithm through High-Resolution Sampling
We present an optimization algorithm that can identify a global minimum of a potentially nonconvex smooth function with high probability, assuming the Gibbs measure of the potential satisfies a logarithmic Sobolev inequality. Our contribution is twofold: on the one hand we propose a global optimization method, which is built on an oracle sampling algorithm producing arbitrarily accurate samples from a given Gibbs measure. On the other hand, we propose a new sampling algorithm, drawing inspirati…

CoDA: Coordinated Diffusion Noise Optimization for Whole-Body Manipulation of Articulated Objects
Synthesizing whole-body manipulation of articulated objects, including body motion, hand motion, and object motion, is a critical yet challenging task with broad applications in virtual humans and robotics. The core challenges are twofold. First, achieving realistic whole-body motion requires tight coordination between the hands and the rest of the body, as their movements are interdependent during manipulation. Second, articulated object manipulation typically involves high degrees of freedom …
