POLARIS: Guiding Small Models to Write Long Stories
Announce Type: new Abstract: Small open-weight models struggle at long-form creative writing: their generated stories either fall far short of the requested length, or their quality significantly degrades as length increases, especially when compared to frontier models. We present POLARIS (Policy Optimization with LLM-as-a-judge rewards and Anchored-Reference Injection for Storywriting), a lower-compute GRPO recipe with two key ingredients: a frontier LLM judge with a structured Story...
Polaris: Coupled Orbital Polar Embeddings for Hierarchical Concept Learning
Announce Type: replace Abstract: Real-world knowledge is often organized as hierarchies such as product taxonomies, medical ontologies, and label trees, yet learning hierarchical representations is challenging due to asymmetric structure and noisy semantics. We introduce Polaris, a polar hyperspherical embedding framework that separates semanticity from hierarchy using angular geometry and radius, enabling the learning of meaning and structure without interference. To map latent...
Polaris: Scaling Up Instruction-Guided Image Generation Towards Millions of Personalized Style Needs
arXiv:2606.01858v1 Announce Type: new Abstract: Users increasingly expect image generation models to quickly adapt to highly diverse and personalized requirements, such as producing images with distinctive styles or characteristics. Traditional approaches rely on fine-tuning, which is costly and difficult to scale. To cope with these limitations, the community has accumulated a growing library of fine-tuned modules and adapters, where each component targets specific generation needs and...
Life in the ancient Arctic: Tiny teeth of newly discovered species suggest it was a cradle of mammalian evolution
Life in the ancient Arctic: Tiny teeth of newly discovered species suggest it was a cradle of mammalian evolution Lisa Lock Scientific Editor Robert Egan Associate Editor A fossil mammal tooth smaller than a grain of rice does not announce itself loudly. It must be hard won from sediment and stone. Then, under a microscope, it reveals itself—no longer just a speck of blackness but a surface of cusps, ridges, and worn edges.
The Cartesian Shortcut: Re-evaluate Vision Reasoning in Polar Coordinate Space
Announce Type: replace Abstract: As current Multimodal Large Language Models rapidly saturate canonical visual reasoning benchmarks, a key question emerges: do these strong scores genuinely reflect robust visual understanding? We identify a pervasive vulnerability, the Cartesian Shortcut: visual reasoning benchmarks prevalently build on orthogonal grid-based layouts that can be readily discretized into explicit textual coordinates. Models systematically exploit this property, heavily...
The World Cup and human trafficking: What the research reveals about the real risks at major sporting events
The World Cup and human trafficking: What the research reveals about the real risks at major sporting events Gaby Clark Scientific Editor Robert Egan Associate Editor As U.S. cities prepare to host the FIFA World Cup, familiar warnings about human trafficking "spikes" at major sporting events have reemerged. Media outlets point to elevated risks, advocacy groups roll out awareness campaigns, and city authorities and law enforcement ramp up anti-trafficking efforts. This is all well intentioned.
The American Missile Crisis
Recent global conflicts, from Russia and Ukraine to Iran and Israel, have seen a resurgent awareness of the frailty of US munitions stock, which has been drawn down by both direct and indirect involvement in these events. While exact stockpile volumes are not disclosed, it is estimated that supplies of US warheads and the missiles that carry them have declined by nearly an order of magnitude since their peak during the Cuban Missile Crisis. Analysts have estimated that in the event of a...
