Building an ARC-2 Solver — From Socratic Panels to a Single Oracle

Building an ARC-2 Solver — From Socratic Panels to a Single Oracle

⋅

From Socratic Panels to the Oracle In Part 1 of this series, I explored a multi-agent Socratic architecture to tackle ARC-2. A supervisor agent orchestrated a panel of specialists, each debating hypotheses about object transformations, symmetry, and spatial reasoning. In Part 2 , I narrowed in on what felt like the real bottleneck: perception. Frontier models could often reason correctly once the rule was clearly articulated — but they struggled to see the structure in the first place. Images and text turned […]

Judge halts Nexstar/Tegna merger after FCC let firms exceed TV ownership limit

⋅

Although the Trump administration approved Nexstar Media Group’s $6.2 billion purchase of Tegna, a US judge has ordered the two companies to stop integrating their assets and operations. US District Judge Troy Nunley, an Obama appointee, issued a temporary restraining order on Friday prohibiting integration of the companies until further rulings by the court. “Defendants must immediately cease all ongoing actions relating to integration and consolidation of Nexstar and Tegna,” wrote Nunley, the chief judge in US District […]

Byte magazine artist Robert Tinney, who illustrated the birth of PCs, dies at 78

⋅

On February 1, Robert Tinney, the illustrator whose airbrushed cover paintings defined the look and feel of pioneering computer magazine Byte for over a decade, died at age 78 in Baker, Louisiana, according to a memorial posted on his official website. As the primary cover artist for Byte from 1975 to the late 1980s, Tinney became one of the first illustrators to give the abstract world of personal computing a coherent visual language, translating topics like artificial intelligence, […]

Learning Unanimously Acceptable Lotteries via Queries

⋅

Many high-stakes AI deployments proceed only if every stakeholder deems the system acceptable relative to their own minimum standard. With randomization over a finite menu of options, this becomes a feasibility question: does there exist a lottery over options that clears all stakeholders’ acceptability bars? We study a query model where the algorithm proposes lotteries and receives only binary accept/reject feedback. We give deterministic and randomized algorithms that either find a unanimously acceptable lottery or certify infeasibility; adaptivity […]

Laws of Learning Dynamics and the Core of Learners

⋅

arXiv:2602.05026v1 Announce Type: new Abstract: We formulate the fundamental laws governing learning dynamics, namely the conservation law and the decrease of total entropy. Within this framework, we introduce an entropy-based lifelong ensemble learning method. We evaluate its effectiveness by constructing an immunization mechanism to defend against transfer-based adversarial attacks on the CIFAR-10 dataset. Compared with a naive ensemble formed by simply averaging models specialized on clean and adversarial samples, the resulting logifold achieves higher accuracy in most test […]

OpenAI is acquiring open source Python tool-maker Astral

⋅

OpenAI announced Thursday that it has entered into an agreement to acquire Astral, the company behind popular open source Python development tools such as uv, Ruff, and ty, and integrate the company into its Codex team. The deal, whose financial terms were not publicly disclosed, will help OpenAI “accelerate our work on Codex and expand what AI can do across the software development lifecycle,” the company said in an announcement post. Integrating Astral’s tools more closely with Codex […]

xplainfi: Feature Importance and Statistical Inference for Machine Learning in R

⋅

We introduce xplainfi, an R package built on top of the mlr3 ecosystem for global, loss-based feature importance methods for machine learning models. Various feature importance methods exist in R, but significant gaps remain, particularly regarding conditional importance methods and associated statistical inference procedures. The package implements permutation feature importance, conditional feature importance, relative feature importance, leave-one-covariate-out, and generalizations thereof, and both marginal and conditional Shapley additive global importance methods. It provides a modular conditional sampling architecture based […]

Motorola suddenly raises budget phone prices up to 50%—you can probably thank AI

Motorola suddenly raises budget phone prices up to 50%—you can probably thank AI

⋅

Motorola announced a new mid-range phone yesterday, the 2026 Moto G Stylus. It’s not exactly a game changer unless you demand a stylus with your smartphone. Despite little in the way of upgrades, the new G Stylus will debut at $500, which is $100 more than last year’s version. It’s now clear that higher pricing will be a trend in Moto’s lineup. Without so much as a peep, Motorola has enacted price increases of up to 50 percent […]

WINFlowNets: Warm-up Integrated Networks Training of Generative Flow Networks for Robotics and Machine Fault Adaptation

⋅

Generative Flow Networks for continuous scenarios (CFlowNets) have shown promise in solving sequential decision-making tasks by learning stochastic policies using a flow and a retrieval network. Despite their demonstrated efficiency compared to state-of-the-art Reinforcement Learning (RL) algorithms, their practical application in robotic control tasks is constrained by the reliance on pre-training the retrieval network. This dependency poses challenges in dynamic robotic environments, where pre-training data may not be readily available or representative of the current environment. This paper […]

Cross-Platform Digital Discourse Analysis of the Israel-Hamas Conflict: Sentiment, Topics, and Event Dynamics

⋅

arXiv:2601.02367v1 Announce Type: new Abstract: The Israeli-Palestinian conflict remains one of the most polarizing geopolitical issues, with the October 2023 escalation intensifying online debate. Social media platforms, particularly Telegram, have become central to real-time news sharing, advocacy, and propaganda. In this study, we analyze Telegram, Twitter/X, and Reddit to examine how conflict narratives are produced, amplified, and contested across different digital spheres. Building on our previous work on Telegram discourse during the 2023 escalation, we extend the analysis […]
