Asymmetric Valleys: Beyond Sharp and Flat Local Minima
Haowei He, Gao Huang, Yang Yuan
Despite the non-convex nature of their loss functions, deep neural networks are known to generalize well when optimized with stochastic gradient descent (SGD). Recent work conjectu…
Spectroscopic determination of the atomic f-electron symmetry underlying hidden order in URuSi
L. Andrew Wray, Jonathan Denlinger, Shih-Wen Huang +5
The low temperature hidden order state of URuSi has long been a subject of intense speculation, and is thought to represent an as yet undetermined many-body quantum state n…
Irreversible proliferation of magnetic moments at cleaved surfaces of the topological Kondo insulator SmB6
Haowei He, Lin Miao, Edwin Augustin +10
The compound SmB is the best established realization of a topological Kondo insulator, in which a topological insulator state is obtained through Kondo coherence. Recent studie…
Disorder enabled band structure engineering of a topological insulator surface
Yishuai Xu, Janet Chiu, Lin Miao +5
Three dimensional topological insulators are bulk insulators with topological electronic order that gives rise to conducting light-like surface states. These surface…
Observation of a Topological Insulator Dirac Cone Reshaped by Non-magnetic Impurity Resonance
Lin Miao, Yishuai Xu, Wenhan Zhang +10
The massless Dirac electrons found at topological insulator surfaces are thought to be influenced very little by weak, non-magnetic disorder. However, a resonance effect of strongl…
Can Pretext-Based Self-Supervised Learning Be Boosted by Downstream Data? A Theoretical Analysis
Jiaye Teng, Weiran Huang, Haowei He
Pretext-based self-supervised learning learns the semantic representation via a handcrafted pretext task over unlabeled data and then uses the learned representation for downstream…
Charge transfer excitations in VUV and soft X-ray resonant scattering spectroscopies
Edwin Augustin, Haowei He, Lin Miao +3
The utility of resonant scattering spectroscopies for identifying electronic symmetries and density distributions changes dramatically as a function of photon energy. In the hard X…
Measurement of collective excitations in VO by resonant inelastic X-ray scattering
Haowei He, A. X. Gray, P. Granitzka +14
Vanadium dioxide is of broad interest as a spin-1/2 electron system that realizes a metal-insulator transition near room temperature, due to a combination of strongly correlated an…
TableReasoner: Advancing Table Reasoning Framework with Large Language Models
Sishi Xiong, Dakai Wang, Yu Zhao +8
The paper presents our system developed for table question answering (TQA). TQA tasks face challenges due to the characteristics of real-world tabular data, such as large size, inc…
Anomaly Detection with Test Time Augmentation and Consistency Evaluation
Haowei He, Jiaye Teng, Yang Yuan
Deep neural networks are known to be vulnerable to unseen data: they may wrongly assign high confidence stcores to out-distribuion samples. Recent works try to solve the problem us…
Dual Attention Residuals
Xingda Yu, Yining Li, Xinzhang Liu +5
Recent work extends Transformer residual pathways along two complementary axes: historical retrieval selects information from earlier depths, whereas multi-stream methods maintain…
High temperature singlet-based magnetism from Hund's rule correlations
Lin Miao, Rourav Basak, Sheng Ran +17
Uranium compounds can manifest a wide range of fascinating many-body phenomena, and are often thought to be poised at a crossover between localized and itinerant regimes for 5f ele…
EVBattery: A Large-Scale Electric Vehicle Dataset for Battery Health and Capacity Estimation
Haowei He, Jingzhao Zhang, Yanan Wang +9
Electric vehicles (EVs) play an important role in reducing carbon emissions. As EV adoption accelerates, safety issues caused by EV batteries have become an important research topi…
Where Does Long-Context Supervision Actually Go? Effective-Context Exposure Balancing
Jinchang Zhu, Jindong Li, Chengyu Zou +4
Long-context adaptation is often viewed as window scaling, but this misses a token-level supervision mismatch: in packed training with document masking, each target token's effecti…
Training Report of TeleChat3-MoE
Xinzhang Liu, Chao Wang, Zhihao Yang +51
TeleChat3-MoE is the latest series of TeleChat large language models, featuring a Mixture-of-Experts (MoE) architecture with parameter counts ranging from 105 billion to over one t…
Trade-off Between Efficiency and Consistency for Removal-based Explanations
Yifan Zhang, Haowei He, Zhiquan Tan +1
In the current landscape of explanation methodologies, most predominant approaches, such as SHAP and LIME, employ removal-based techniques to evaluate the impact of individual feat…
