Picosecond volume expansion drives a later-time insulator-metal transition in a nano-textured Mott Insulator

Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Anita Verma, Denis Golež, Oleg Yu. Gorobtsov, Kelson Kaj, Ryan Russell | Summary: Technology moves towards ever faster switching between different electronic and magnetic states of matter. Manipulating properties at terahertz rates requires accessing the intrinsic timescales of electrons (femtoseconds) and associated phonons (10s of femtoseconds […]

Attribute-Consistent Knowledge Graph Representation Learning for Multi-Modal Entity Alignment

Kavli Affiliate: Lihong Wang | First 5 Authors: Qian Li, Shu Guo, Yangyifei Luo, Cheng Ji, Lihong Wang | Summary: The multi-modal entity alignment (MMEA) aims to find all equivalent entity pairs between multi-modal knowledge graphs (MMKGs). Rich attributes and neighboring entities are valuable for the alignment task, but existing works ignore contextual gap problems […]

Enhancing Clinical Evidence Recommendation with Multi-Channel Heterogeneous Learning on Evidence Graphs

Kavli Affiliate: Xiang Zhang | Authors: Maolin Luo, Xiang Zhang | Summary: Clinical evidence encompasses the associations and impacts between patients, interventions (such as drugs or physiotherapy), problems, and outcomes. The goal of recommending clinical evidence is to provide medical practitioners with relevant information to support their decision-making processes and to generate new evidence. Our […]

Action Pick-up in Dynamic Action Space Reinforcement Learning

Kavli Affiliate: Feng Wang | Authors: Jiaqi Ye, Xiaodong Li, Pangjing Wu, Feng Wang | Summary: Most reinforcement learning algorithms are based on a key assumption that Markov decision processes (MDPs) are stationary. However, non-stationary MDPs with dynamic action space are omnipresent in real-world scenarios. Yet problems of dynamic action space reinforcement learning have been […]
