arXiv:2601.08982v1 Announce Type: new Abstract: Segment Anything (SAM) provides an unprecedented foundation for human segmentation, but may struggle under occlusion, where keypoints may be partially or fully invisible. We adapt SAM 2.1 for pose-guided segmentation with minimal encoder modifications, retaining its strong generalization. Using a fine-tuning strategy called PoseMaskRefine, we incorporate pose keypoints with high visibility into the iterative correction process originally employed by SAM, yielding improved robustness and accuracy across multiple datasets. During inference, we simplify prompting […]

Pathfinding and target selection algorithms play a critical role in real-time strategy and mobile games, directly influencing gameplay balance, fairness, and player skill expression. Unlike traditional shortest-path algorithms such as A*, many commercial games intentionally employ simplified or constrained pathfinding to preserve strategic depth. This paper presents a modeling and experimental analysis of troop pathfinding and target selection behavior inspired by Clash of Clans, with a focus on Clan War attack scenarios involving troop movement toward Town Halls […]

Score-based generative models have recently achieved remarkable success. While they are usually parameterized by the score, an alternative way is to use a series of time-dependent energy-based models (EBMs), where the score is obtained from the negative input-gradient of the energy. Crucially, EBMs can be leveraged not only for generation, but also for tasks such as compositional sampling or building Boltzmann Generators via Monte Carlo methods. However, training EBMs remains challenging. Direct maximum likelihood is computationally prohibitive due […]

Watts critiques our scholastic obsessions and urges an experiential approach to life, blending the spiritual and concrete like a Zen gardener planting mysteries among truths. He laments our sterile materialism and bureaucratic rigidity, championing a dance with risk, creativity, and nonverbal wisdom. With tales of mystics, scientists, and madmen, he celebrates the spice of oddballs, the necessity of nonsense, and the ineffable richness of being alive.

When building RAG pipelines and agent systems, I kept running into the same issue: most web crawlers return raw HTML or noisy text that still requires significant post-processing before it’s usable for embeddings. I’ve been experimenting with a crawler design that focuses specifically on AI ingestion, not generic scraping. The key design choices are: isolating main content on docs-heavy sites (removing nav, footers, TOCs) converting pages into structure-preserving markdown chunking by document hierarchy (headings) instead of fixed token […]

OpenAI is launching the OpenAI Academy for News Organizations, a new learning hub built with the American Journalism Project and The Lenfest Institute to help newsrooms use AI effectively. The Academy offers training, practical use cases, and responsible-use guidance to support journalists, editors, and publishers as they adopt AI in their reporting and operations.
