AOCIL: Exemplar-free Analytic Online Class Incremental Learning with Low Time and Resource Consumption

no code implementations23 Mar 2024 Huiping Zhuang, Yuchen Liu, Run He, Kai Tong, Ziqian Zeng, Cen Chen, Yi Wang, Lap-Pui Chau

Online Class Incremental Learning (OCIL) aims to train the model in a task-by-task manner, where data arrive in mini-batches at a time while previous data are not accessible.

G-ACIL: Analytic Learning for Exemplar-Free Generalized Class Incremental Learning

1 code implementation23 Mar 2024 Huiping Zhuang, Yizhu Chen, Di Fang, Run He, Kai Tong, Hongxin Wei, Ziqian Zeng, Cen Chen

The generalized CIL (GCIL) aims to address the CIL problem in a more real-world scenario, where incoming data have mixed data categories and unknown sample size distribution, leading to intensified forgetting.

On the use of Silver Standard Data for Zero-shot Classification Tasks in Information Extraction

1 code implementation28 Feb 2024 Jianwei Wang, Tianyin Wang, Ziqian Zeng

Recent zero-shot classification methods converted the task to other NLP tasks (e. g., textual entailment) and used off-the-shelf models of these NLP tasks to directly perform inference on the test data without using a large amount of IE annotation data.

Chimera: A Lossless Decoding Method for Accelerating Large Language Models Inference by Fusing all Tokens

1 code implementation24 Feb 2024 Ziqian Zeng, Jiahong Yu, Qianshi Pang, ZiHao Wang, Huiping Zhuang, HongEn Shao, Xiaofeng Zou

Within this framework, we introduce a lightweight draft model that effectively utilizes previously generated tokens to predict subsequent words.

Zero-shot Explainable Mental Health Analysis on Social Media by Incorporating Mental Scales

no code implementations9 Feb 2024 Wenyu Li, Yinuo Zhu, Xin Lin, Ming Li, Ziyue Jiang, Ziqian Zeng

Traditional discriminative approaches in mental health analysis are known for their strong capacity but lack interpretability and demand large-scale annotated data.

From Ultra-Fine to Fine: Fine-tuning Ultra-Fine Entity Typing Models to Fine-grained

1 code implementation11 Dec 2023 Hongliang Dai, Ziqian Zeng

We can simply fine-tune the previously trained model with a small number of examples annotated under this schema.

Learning with Silver Standard Data for Zero-shot Relation Extraction

no code implementations25 Nov 2022 Tianyin Wang, Jianwei Wang, Ziqian Zeng

In this paper, we propose to first detect a small amount of clean data from silver standard data and then use the selected clean data to finetune the pretrained model.

Variational Weakly Supervised Sentiment Analysis with Posterior Regularization

1 code implementation EACL 2021 Ziqian Zeng, Yangqiu Song

In this paper, we propose a posterior regularization framework for the variational approach to the weakly supervised sentiment analysis to better control the posterior distribution of the label assignment.
