Geodesic Flow Kernels for Semi-Supervised Learning on Mixed-Variable Tabular Dataset
Yoontae Hwang, Yongjae Lee
Tabular data poses unique challenges due to its heterogeneous nature, combining both continuous and categorical variables. Existing approaches often struggle to effectively capture…
Bright and Purcell-enhanced single photon emission from a silicon G center
Kyu-Young Kim, Chang-Min Lee, Amirehsan Boreiri +5
Silicon G centers show significant promise as single photon sources in a scalable silicon platform. But these color centers have large non-radiative decay and a low Debye-Waller fa…
Catalytic channels are the only noise-robust catalytic processes
Jeongrak Son, Ray Ganardi, Shintaro Minagawa +3
Catalysis refers to the possibility of enabling otherwise inaccessible quantum state transitions by supplying an auxiliary system, provided that the auxiliary is returned to its in…
Electronic Trap Detection with Carrier-Resolved Photo-Hall Effect
Oki Gunawan, Chaeyoun Kim, Bonfilio Nainggolan +11
Electronic trap states are a critical yet unavoidable aspect of semiconductor devices, impacting performance of various electronic devices such as transistors, memory devices, sola…
A Benchmark Dataset for Collaborative SLAM in Service Environments
Harin Park, Inha Lee, Minje Kim +2
As service environments have become diverse, they have started to demand complicated tasks that are difficult for a single robot to complete. This change has led to an interest in…
Tuning One Dimensional Plasmonic Gap at Nanometer Scale for Advanced SERS Detection
Mahsa Haddadi Moghaddam, Sobhagyam Sharma, Daehwan Park +1
The hotspots, which are typically found in nanogaps between metal structures, are critical for the enhancement of the electromagnetic field. Surface-enhanced Raman scattering (SERS…
Generative AI for Brane Configurations and Coamoeba
Rak-Kyeong Seong
We introduce a generative AI model to obtain Type IIB brane configurations that realize toric phases of a family of 4d N=1 supersymmetric gauge theories. These 4d N=1 quiver gauge…
Futaki Invariants and Reflexive Polygons
Jiakang Bao, Eugene Choi, Yang-Hui He +2
Futaki invariants of the classical moduli space of 4d N=1 supersymmetric gauge theories determine whether they have a conformal fixed point in the IR. We systematically compute the…
Multipartite quantum states over time from two fundamental assumptions
Seok Hyung Lie, James Fullwood
The theory of quantum states over time extends the density operator formalism into the temporal domain, providing a unified of treatment of timelike and spacelike separated systems…
Beyond Trivial Edges: A Fractional Approach to Cohesive Subgraph Detection in Hypergraphs
Hyewon Kim, Woocheol Shin, Dahee Kim +3
Hypergraphs serve as a powerful tool for modeling complex relationships across domains like social networks, transactions, and recommendation systems. The (k,g)-core model effectiv…
