Sensor Network Localization via Riemannian Conjugate Gradient and Rank Reduction: An Extended Version

no code implementations13 Mar 2024 Yicheng Li, Xinghua Sun

The SNL is formulated as an Euclidean Distance Matrix Completion (EDMC) problem under the unit ball sample model.

Generalization Error Curves for Analytic Spectral Algorithms under Power-law Decay

no code implementations3 Jan 2024 Yicheng Li, Weiye Gan, Zuoqiang Shi, Qian Lin

The generalization error curve of certain kernel regression method aims at determining the exact order of generalization error with various source condition, noise level and choice of the regularization parameter rather than the minimax rate.

Optimal Rates of Kernel Ridge Regression under Source Condition in Large Dimensions

no code implementations2 Jan 2024 Haobo Zhang, Yicheng Li, Weihao Lu, Qian Lin

Motivated by the studies of neural networks (e. g., the neural tangent kernel theory), we perform a study on the large-dimensional behavior of kernel ridge regression (KRR) where the sample size $n \asymp d^{\gamma}$ for some $\gamma > 0$.

Mixed Distillation Helps Smaller Language Model Better Reasoning

no code implementations17 Dec 2023 Chenglin Li, Qianglong Chen, Liangyue Li, Caiyu Wang, Yicheng Li, Zulong Chen, Yin Zhang

While large language models (LLMs) have demonstrated exceptional performance in recent natural language processing (NLP) tasks, their deployment poses substantial challenges due to high computational and memory demands in real-world applications.

Optimal Rate of Kernel Regression in Large Dimensions

no code implementations8 Sep 2023 Weihao Lu, Haobo Zhang, Yicheng Li, Manyun Xu, Qian Lin

We perform a study on kernel regression for large-dimensional data (where the sample size $n$ is polynomially depending on the dimension $d$ of the samples, i. e., $n\asymp d^{\gamma}$ for some $\gamma >0$ ).

On the Optimality of Misspecified Kernel Ridge Regression

no code implementations12 May 2023 Haobo Zhang, Yicheng Li, Weihao Lu, Qian Lin

In the misspecified kernel ridge regression problem, researchers usually assume the underground true function $f_{\rho}^{*} \in [\mathcal{H}]^{s}$, a less-smooth interpolation space of a reproducing kernel Hilbert space (RKHS) $\mathcal{H}$ for some $s\in (0, 1)$.

On the Eigenvalue Decay Rates of a Class of Neural-Network Related Kernel Functions Defined on General Domains

no code implementations4 May 2023 Yicheng Li, Zixiong Yu, Guhan Chen, Qian Lin

In this paper, we provide a strategy to determine the eigenvalue decay rate (EDR) of a large class of kernel functions defined on a general domain rather than $\mathbb S^{d}$.

Kernel interpolation generalizes poorly

no code implementations28 Mar 2023 Yicheng Li, Haobo Zhang, Qian Lin

One of the most interesting problems in the recent renaissance of the studies in kernel regression might be whether the kernel interpolation can generalize well, since it may help us understand the `benign overfitting henomenon' reported in the literature on deep networks.

Development of a Hardware-in-the-loop Testbed for Laboratory Performance Verification of Flexible Building Equipment in Typical Commercial Buildings

no code implementations31 Jan 2023 Zhelun Chen, Jin Wen, Steven T. Bushby, L. James Lo, Zheng O'Neill, W. Vance Payne, Amanda Pertzborn, Caleb Calfa, Yangyang Fu, Gabriel Grajewski, Yicheng Li, Zhiyao Yang

The development of strategies that exploit these flexibilities could be facilitated by publicly available high-resolution datasets illustrating how control of HVAC systems in commercial buildings can be used in different climate zones to shape the energy use profile of a building for grid needs.

An Integrated Enhancement Solution for 24-hour Colorful Imaging

no code implementations10 May 2020 Feifan Lv, Yinqiang Zheng, Yicheng Li, Feng Lu

The current industry practice for 24-hour outdoor imaging is to use a silicon camera supplemented with near-infrared (NIR) illumination.

Instance-level Human Parsing via Part Grouping Network

1 code implementation ECCV 2018 Ke Gong, Xiaodan Liang, Yicheng Li, Yimin Chen, Ming Yang, Liang Lin

Instance-level human parsing towards real-world human analysis scenarios is still under-explored due to the absence of sufficient data resources and technical difficulty in parsing multiple instances in a single pass.
