Evaluating and Improving Tool-Augmented Computation-Intensive Math Reasoning

1 code implementation4 Jun 2023 Beichen Zhang, Kun Zhou, Xilin Wei, Wayne Xin Zhao, Jing Sha, Shijin Wang, Ji-Rong Wen

Based on this finding, we propose a new approach that can deliberate the reasoning steps with tool interfaces, namely \textbf{DELI}.

ChatCoT: Tool-Augmented Chain-of-Thought Reasoning on Chat-based Large Language Models

1 code implementation23 May 2023 Zhipeng Chen, Kun Zhou, Beichen Zhang, Zheng Gong, Wayne Xin Zhao, Ji-Rong Wen

To improve the reasoning abilities, we propose \textbf{ChatCoT}, a tool-augmented chain-of-thought reasoning framework for chat-based LLMs.

A Survey of Large Language Models

1 code implementation31 Mar 2023 Wayne Xin Zhao, Kun Zhou, Junyi Li, Tianyi Tang, Xiaolei Wang, Yupeng Hou, Yingqian Min, Beichen Zhang, Junjie Zhang, Zican Dong, Yifan Du, Chen Yang, Yushuo Chen, Zhipeng Chen, Jinhao Jiang, Ruiyang Ren, YiFan Li, Xinyu Tang, Zikang Liu, Peiyu Liu, Jian-Yun Nie, Ji-Rong Wen

To discriminate the difference in parameter scale, the research community has coined the term large language models (LLM) for the PLMs of significant size.

Quantitative Assessment of Drought Impacts Using XGBoost based on the Drought Impact Reporter

no code implementations4 Nov 2022 Beichen Zhang, Fatima K. Abu Salem, Michael J. Hayes, Tsegaye Tadesse

Under climate change, the increasing frequency, intensity, and spatial extent of drought events lead to higher socio-economic costs.


JiuZhang: A Chinese Pre-trained Language Model for Mathematical Problem Understanding

1 code implementation13 Jun 2022 Wayne Xin Zhao, Kun Zhou, Zheng Gong, Beichen Zhang, Yuanhang Zhou, Jing Sha, Zhigang Chen, Shijin Wang, Cong Liu, Ji-Rong Wen

Considering the complex nature of mathematical texts, we design a novel curriculum pre-training approach for improving the learning of mathematical PLMs, consisting of both basic and advanced courses.

Debiased Contrastive Learning of Unsupervised Sentence Representations

1 code implementation ACL 2022 Kun Zhou, Beichen Zhang, Wayne Xin Zhao, Ji-Rong Wen

In DCLR, we design an instance weighting method to punish false negatives and generate noise-based negatives to guarantee the uniformity of the representation space.

Rethinking Graph Neural Architecture Search from Message-passing

1 code implementation CVPR 2021 Shaofei Cai, Liang Li, Jincan Deng, Beichen Zhang, Zheng-Jun Zha, Li Su, Qingming Huang

Inspired by the strong searching capability of neural architecture search (NAS) in CNN, this paper proposes Graph Neural Architecture Search (GNAS) with novel-designed search space.

State-Relabeling Adversarial Active Learning

1 code implementation CVPR 2020 Beichen Zhang, Liang Li, Shijie Yang, Shuhui Wang, Zheng-Jun Zha, Qingming Huang

In this paper, we propose a state relabeling adversarial active learning model (SRAAL), that leverages both the annotation and the labeled/unlabeled state information for deriving the most informative unlabeled samples.
