OpenEval: Benchmarking Chinese LLMs across Capability, Alignment and Safety

no code implementations18 Mar 2024 Chuang Liu, Linhao Yu, Jiaxuan Li, Renren Jin, Yufei Huang, Ling Shi, Junhui Zhang, Xinmeng Ji, Tingting Cui, Tao Liu, Jinwang Song, Hongying Zan, Sun Li, Deyi Xiong

In addition to these benchmarks, we have implemented a phased public evaluation and benchmark update strategy to ensure that OpenEval is in line with the development of Chinese LLMs or even able to provide cutting-edge benchmark datasets to guide the development of Chinese LLMs.

Memory-Constrained Algorithms for Convex Optimization via Recursive Cutting-Planes

no code implementations16 Jun 2023 Moïse Blanchard, Junhui Zhang, Patrick Jaillet

We propose a family of recursive cutting-plane algorithms to solve feasibility problems with constrained memory, which can also be used for first-order convex optimization.

Quadratic Memory is Necessary for Optimal Query Complexity in Convex Optimization: Center-of-Mass is Pareto-Optimal

no code implementations9 Feb 2023 Moïse Blanchard, Junhui Zhang, Patrick Jaillet

For the feasibility problem, in which an algorithm only has access to a separation oracle, we show a stronger trade-off: for at most $d^{2-\delta}$ memory, the number of queries required is $\tilde\Omega(d^{1+\delta})$.

Direct Speech-to-speech Translation without Textual Annotation using Bottleneck Features

no code implementations12 Dec 2022 Junhui Zhang, Junjie Pan, Xiang Yin, Zejun Ma

Speech-to-speech translation directly translates a speech utterance to another between different languages, and has great potential in tasks such as simultaneous interpretation.

Sparse and Safe Frequency Regulation for Inverter Intensive Microgrids

no code implementations10 Jul 2022 Junhui Zhang, Lizhi Ding, Xiaonan Lu, Wenyuan Tang

This paper developed a novel control approach for the sparse and safe frequency regulation for inverter intensive microgrids (MGs).

A Novel Chinese Dialect TTS Frontend with Non-Autoregressive Neural Machine Translation

no code implementations10 Jun 2022 Junhui Zhang, Wudi Bao, Junjie Pan, Xiang Yin, Zejun Ma

In this paper, we propose a novel Chinese dialect TTS frontend with a translation module, which converts Mandarin text into dialectic expressions to improve the intelligibility and naturalness of synthesized speech.

Square Root Principal Component Pursuit: Tuning-Free Noisy Robust Matrix Recovery

no code implementations NeurIPS 2021 Junhui Zhang, Jingkai Yan, John Wright

We show that a single, universal choice of the regularization parameter suffices to achieve reconstruction error proportional to the (a priori unknown) noise level.
