Subspace-Decomposed JEPAs: Disentangling Progression and Content in Latent World Models
arXiv:2605.31111v1 Announce Type: new Abstract: Joint-Embedding Predictive Architectures (JEPAs) learn compact latent world models by predicting future embeddings, but no single coordinate of the latent is designated to encode task progression. We carve the JEPA latent into two orthogonal subspaces with disjoint roles: a low-dimensional progression subspace shaped by a cosine-margin triplet loss, and a high-dimensional content subspace regularised by the existing SIGReg objective of LeWM. We...
Brain2Text Decoding Model Reveals the Neural Mechanisms of Visual Semantic Processing
arXiv:2503.22697v3 Announce Type: replace-cross Abstract: Decoding sensory experiences from neural activity to reconstruct human-perceived visual stimuli and semantic content remains a challenge in neuroscience and artificial intelligence. Despite notable progress in current brain decoding models, a critical gap still persists in their systematic integration with established neuroscientific theories and the exploration of underlying neural mechanisms. Here, we present a novel framework that...
VikingMem: A Memory Base Management System for Stateful LLM-based Applications
arXiv:2605.29640v2 Announce Type: replace Abstract: Large Language Models have revolutionized interactive applications; however, their finite context windows pose a critical data management challenge for maintaining stateful, long-term interactions. Existing memory approaches often rely on simplistic extraction methods that lead to incomplete memories or use rigid, single-purpose memory extraction prompts tailored to a single use case, such as chatbots. Consequently, they lack...
Learning Agent-Compatible Context Management for Long-Horizon Tasks
Announce Type: new Abstract: LLM agents increasingly face long-horizon tasks such as web search and deep research in real-world applications, where accumulated context can cause long-context degradation and reasoning failures. Prior work mitigates this through context management with agent-side context control or fixed strategies such as summarization, which require training the agent itself for adaptation - making it impractical for closed-source agents and ignoring that different agents...
Evolutionary scientists details why 'existential angst' makes progressives less happy than conservatives
Conservatives are happier than liberals, and evolutionary behavioral scientist Dr. Gad Saad says there's a simple reason why. Appearing on Fox News' "Hang Out with Sean Hannity" podcast, Saad pointed to decades of "unequivocal" research showing conservatives consistently report higher levels of happiness than their counterparts on the left, arguing the difference stems from how each side views society. "I offer a speculative explanation, but I think it makes sense," he said in Tuesday's episode.
Digging Up Citations: FOSSIL, a Dataset and Workflow for Reference Extraction in Law and the Humanities
arXiv:2606.01109v1 Announce Type: new Abstract: Citation extraction tools are designed for the structured end-of-document bibliographies of the natural sciences, but law and humanities scholarship cites references primarily in footnotes, where bibliographic data is interleaved with commentary and cross-references and varies widely across languages and styles. To address the scarcity of suitable gold-standard resources, we present FOSSIL (Footnote-based Open-access SSH Scientific Instance...

Building Reliable Long-Form Generation via Hallucination Rejection Sampling
arXiv:2606.03628v1 Announce Type: new Abstract: Large language models (LLMs) have achieved remarkable progress in open-ended text generation, yet they remain prone to hallucinating incorrect or unsupported content, which undermines their reliability. This issue is exacerbated in long-form generation due to hallucination snowballing, a phenomenon where early errors propagate and compound into subsequent outputs. To address this challenge, we propose a novel inference-time hallucination...
Israel captures Beaufort Castle in Lebanon: What makes the 900-year-old fortress strategic target
Israeli forces have captured the historic Beaufort Castle in southern Lebanon, marking its one of the deepest advances into Lebanese territory. The assault was part of a broader ground offensive that pushed Israeli forces beyond the Litani River, marking their deepest incursion into Lebanon since 2000. Israeli forces captured Beaufort Castle after days of intense airstrikes, artillery bombardment and ground fighting against Hezbollah positions in southern Lebanon.
Mellum2 Technical Report
arXiv:2605.31268v1 Announce Type: new Abstract: We present Mellum 2, an open-weight 12B-parameter Mixture-of-Experts (MoE) language model with 2.5B active parameters per token. Mellum 2 is a general-purpose language model specialized in software engineering, spanning code generation and editing, debugging, multi-step reasoning, tool use and function calling, agentic coding, and conversational programming assistance, and it is the successor to the completion-focused 4B dense Mellum model. The...
