Naive Bayes-based Context Extension for Large Language Models

1 code implementation26 Mar 2024 Jianlin Su, Murtadha Ahmed, Wenbo, Luo Ao, Mingren Zhu, Yunfeng Liu

However, conventional In-Context Learning (ICL) approaches are often impeded by length limitations of transformer architecture, which pose challenges when attempting to effectively integrate supervision from a substantial number of demonstration examples.

Rank-Aware Negative Training for Semi-Supervised Text Classification

1 code implementation13 Jun 2023 Ahmed Murtadha, Shengfeng Pan, Wen Bo, Jianlin Su, Xinxin Cao, Wenze Zhang, Yunfeng Liu

To alleviate the noisy information, we adapt a reasoning with uncertainty-based approach to rank the unlabeled texts based on the evidential support received from the labeled texts.

ZLPR: A Novel Loss for Multi-label Classification

no code implementations5 Aug 2022 Jianlin Su, Mingren Zhu, Ahmed Murtadha, Shengfeng Pan, Bo Wen, Yunfeng Liu

To support the application of deep learning in multi-label classification (MLC) tasks, we propose the ZLPR (zero-bounded log-sum-exp \& pairwise rank-based) loss in this paper.

BERT-ASC: Implicit Aspect Representation Learning through Auxiliary-Sentence Construction for Sentiment Analysis

1 code implementation22 Mar 2022 Murtadha Ahmed, Shengfeng Pan, Jianlin Su, Xinxin Cao, Wenze Zhang, Bo Wen, Yunfeng Liu

Unfortunately, the aspect is often expressed implicitly through a set of representatives and thus renders implicit mapping process unattainable unless sufficient labeled examples are available.

The method to increase the thrust of high Mach number Scramjets

no code implementations29 Jan 2021 Yunfeng Liu, Xin Han, Wenshuo Zhang, Kaifu Ma

If the velocity of pre-combustion shock wave is faster than the velocity in the isolator, it will propagate upstream and cause the engine unstart.

TableQA: a Large-Scale Chinese Text-to-SQL Dataset for Table-Aware SQL Generation

2 code implementations10 Jun 2020 Ningyuan Sun, Xuefeng Yang, Yunfeng Liu

Existing NL2SQL datasets assume that condition values should appear exactly in natural language questions and the queries are answerable given the table.
