Analysis of Multi-epoch JWST Images of $sim 300$ Little Red Dots: Tentative Detection of Variability in a Minority of Sources

Kavli Affiliate: Linhua Jiang | First 5 Authors: Zijian Zhang, Linhua Jiang, Weiyang Liu, Luis C. Ho, | Summary: James Webb Space Telescope (JWST) has revealed a population of red and compact sources at $z gtrsim 5$ known as “Little Red Dots” (LRDs) that are likely active galactic nuclei (AGNs). Here we present a comprehensive […]

HOBBIT: A Mixed Precision Expert Offloading System for Fast MoE Inference

Kavli Affiliate: Jing Wang | First 5 Authors: Peng Tang, Jiacheng Liu, Xiaofeng Hou, Yifei Pu, Jing Wang | Summary: The Mixture-of-Experts (MoE) architecture has demonstrated significant advantages in the era of Large Language Models (LLMs), offering enhanced capabilities with reduced inference costs. However, deploying MoE-based LLMs on memoryconstrained edge devices remains challenging due to […]

Similarity and Dissimilarity Guided Co-association Matrix Construction for Ensemble Clustering

Kavli Affiliate: Ran Wang | First 5 Authors: Xu Zhang, Yuheng Jia, Mofei Song, Ran Wang, | Summary: Ensemble clustering aggregates multiple weak clusterings to achieve a more accurate and robust consensus result. The Co-Association matrix (CA matrix) based method is the mainstream ensemble clustering approach that constructs the similarity relationships between sample pairs according […]

Redefining in Dictionary: Towards a Enhanced Semantic Understanding of Creative Generation

Kavli Affiliate: Jing Wang | First 5 Authors: Fu Feng, Yucheng Xie, Jing Wang, Xin Geng, | Summary: Creativity, both in human and diffusion models, remains an inherently abstract concept; thus, simply adding "creative" to a prompt does not yield reliable semantic recognition by the model. In this work, we concretize the abstract notion of […]

Redefining in Dictionary: Towards an Enhanced Semantic Understanding of Creative Generation

Kavli Affiliate: Jing Wang | First 5 Authors: Fu Feng, Yucheng Xie, Xu Yang, Jing Wang, Xin Geng | Summary: “Creative” remains an inherently abstract concept for both humans and diffusion models. While text-to-image (T2I) diffusion models can easily generate out-of-domain concepts like “a blue banana”, they struggle with generating combinatorial objects such as “a […]

The LAMOST Spectroscopic Survey of Supergiants in M31 and M33

Kavli Affiliate: Huawei Zhang | First 5 Authors: Hao Wu, Yang Huang, Huawei Zhang, Haibo Yuan, Zhiying Huo | Summary: We present systematic identifications of supergiants of M31/M33 based on massive LAMOST spectroscopic survey. Radial velocities of nearly 5000 photometrically selected M31/M33 supergiant candidates have been properly derived from the qualified spectra released in LAMOST […]
