Approximation of RKHS Functionals by Neural Networks

no code implementations18 Mar 2024 Tian-Yi Zhou, Namjoon Suh, Guang Cheng, Xiaoming Huo

Motivated by the abundance of functional data such as time series and images, there has been a growing interest in integrating such data into neural networks and learning maps from function spaces to R (i. e., functionals).

Benefits of Transformer: In-Context Learning in Linear Regression Tasks with Unstructured Data

no code implementations1 Feb 2024 Yue Xing, Xiaofeng Lin, Namjoon Suh, Qifan Song, Guang Cheng

In practice, it is observed that transformer-based models can learn concepts in context in the inference stage.

On Excess Risk Convergence Rates of Neural Network Classifiers

no code implementations26 Sep 2023 Hyunouk Ko, Namjoon Suh, Xiaoming Huo

The recent success of neural networks in pattern recognition and classification problems suggests that neural networks possess qualities distinct from other more classical classifiers such as SVMs or boosting classifiers.

Generalization of Overparametrized Deep Neural Network Under Noisy Observations

no code implementations ICLR 2022 Namjoon Suh, Hyunouk Ko, Xiaoming Huo

We study the generalization properties of the overparameterized deep neural network (DNN) with Rectified Linear Unit (ReLU) activations.

Asymptotic Theory of $\ell_1$-Regularized PDE Identification from a Single Noisy Trajectory

no code implementations12 Mar 2021 Yuchen He, Namjoon Suh, Xiaoming Huo, Sungha Kang, Yajun Mei

We provide a set of sufficient conditions which guarantee that, from a single trajectory data denoised by a Local-Polynomial filter, the support of $\mathbf{c}(\lambda)$ asymptotically converges to the true signed-support associated with the underlying PDE for sufficiently many data and a certain range of $\lambda$.

Factor Analysis on Citation, Using a Combined Latent and Logistic Regression Model

no code implementations2 Dec 2019 Namjoon Suh, Xiaoming Huo, Eric Heim, Lee Seversky

We propose a combined model, which integrates the latent factor model and the logistic regression model, for the citation network.

Review on Parameter Estimation in HMRF

no code implementations20 Nov 2017 Namjoon Suh

In following section, we expand this idea on estimating parameters in Gaussian Hidden Markov Spatial-Temporal Random Field, and display results on two performed experiments.
