Beyond Static Evaluation: A Dynamic Approach to Assessing AI Assistants' API Invocation Capabilities

1 code implementation17 Mar 2024 Honglin Mu, Yang Xu, Yunlong Feng, Xiaofeng Han, Yitong Li, Yutai Hou, Wanxiang Che

With the rise of Large Language Models (LLMs), AI assistants' ability to utilize tools, especially through API calls, has advanced notably.

OpenSLU: A Unified, Modularized, and Extensible Toolkit for Spoken Language Understanding

1 code implementation17 May 2023 Libo Qin, Qiguang Chen, Xiao Xu, Yunlong Feng, Wanxiang Che

Spoken Language Understanding (SLU) is one of the core components of a task-oriented dialogue system, which aims to extract the semantic meaning of user queries (e. g., intents and slots).

MixPro: Simple yet Effective Data Augmentation for Prompt-based Learning

no code implementations19 Apr 2023 Bohan Li, Longxu Dou, Yutai Hou, Yunlong Feng, Honglin Mu, Qingfu Zhu, Qinghua Sun, Wanxiang Che

Prompt-based learning has shown considerable promise in reformulating various downstream tasks as cloze problems by combining original input with a predetermined template.

Semantic-Guided Generative Image Augmentation Method with Diffusion Models for Image Classification

no code implementations4 Feb 2023 Bohan Li, Xiao Xu, Xinghao Wang, Yutai Hou, Yunlong Feng, Feng Wang, Xuanliang Zhang, Qingfu Zhu, Wanxiang Che

In contrast, generative methods bring more image diversity in the augmented images but may not preserve semantic consistency, thus incorrectly changing the essential semantics of the original image.

A Framework of Learning Through Empirical Gain Maximization

no code implementations29 Sep 2020 Yunlong Feng, Qiang Wu

Furthermore, it is shown that several well-known robust nonconvex regression paradigms, such as Tukey regression and truncated least square regression, can be reformulated into this new framework.

A Statistical Learning Assessment of Huber Regression

no code implementations27 Sep 2020 Yunlong Feng, Qiang Wu

Third, with an adaptive choice of the scale parameter, we demonstrate that Huber regression estimators can be asymptotic mean regression calibrated under $(1+\epsilon)$-moment conditions ($\epsilon>0$).

N-LTP: An Open-source Neural Language Technology Platform for Chinese

1 code implementation EMNLP (ACL) 2021 Wanxiang Che, Yunlong Feng, Libo Qin, Ting Liu

We introduce \texttt{N-LTP}, an open-source neural language technology platform supporting six fundamental Chinese NLP tasks: {lexical analysis} (Chinese word segmentation, part-of-speech tagging, and named entity recognition), {syntactic parsing} (dependency parsing), and {semantic parsing} (semantic dependency parsing and semantic role labeling).

New Insights into Learning with Correntropy Based Regression

no code implementations19 Jun 2020 Yunlong Feng

Third, we present some new results when it is utilized to learn the conditional mean function by developing its error bounds and exponential convergence rates under conditional $(1+\epsilon)$-moment assumptions.

Half-Quadratic Alternating Direction Method of Multipliers for Robust Orthogonal Tensor Approximation

1 code implementation3 May 2020 Yuning Yang, Yunlong Feng

In this paper, based on the maximum a posterior estimation, we derive a robust orthogonal tensor CPD model with Cauchy loss, which is resistant to heavy-tailed noise or outliers.

Learning with Correntropy-induced Losses for Regression with Mixture of Symmetric Stable Noise

no code implementations1 Mar 2018 Yunlong Feng, Yiming Ying

Motivated by the practical way of generating non-Gaussian noise or outliers, we introduce mixture of symmetric stable noise, which include Gaussian noise, Cauchy noise, and their mixture as special cases, to model non-Gaussian noise or outliers.

Kernel Density Estimation for Dynamical Systems

no code implementations13 Jul 2016 Hanyuan Hang, Ingo Steinwart, Yunlong Feng, Johan A. K. Suykens

We study the density estimation problem with observations generated by certain dynamical systems that admit a unique underlying invariant Lebesgue density.

Learning theory estimates with observations from general stationary stochastic processes

no code implementations10 May 2016 Hanyuan Hang, Yunlong Feng, Ingo Steinwart, Johan A. K. Suykens

We show that when the stochastic processes satisfy a generalized Bernstein-type inequality, a unified treatment on analyzing the learning schemes with various mixing processes can be conducted and a sharp oracle inequality for generic regularized empirical risk minimization schemes can be established.
