LSROM: Learning Self-Refined Organizing Map for Fast Imbalanced Streaming Data Clustering

no code implementations14 Apr 2024 Yongqi Xu, Yujian Lee, Rong Zou, Yiqun Zhang, Yiu-ming Cheung

That is, the imbalanced degree of clusters varies in different streaming data chunks, leading to corruption in either the accuracy or the efficiency of streaming data analysis based on existing clustering methods.

HiFT: A Hierarchical Full Parameter Fine-Tuning Strategy

no code implementations26 Jan 2024 Yongkang Liu, Yiqun Zhang, Qian Li, Tong Liu, Shi Feng, Daling Wang, Yifei Zhang, Hinrich Schütze

As LMs grow in size, fine-tuning the full parameters of LMs requires a prohibitively large amount of GPU memory.

STICKERCONV: Generating Multimodal Empathetic Responses from Scratch

1 code implementation20 Jan 2024 Yiqun Zhang, Fanheng Kong, Peidong Wang, Shuang Sun, Lingshuai Wang, Shi Feng, Daling Wang, Yifei Zhang, Kaisong Song

Stickers, while widely recognized for enhancing empathetic communication in online interactions, remain underexplored in current empathetic dialogue research, notably due to the challenge of a lack of comprehensive datasets.

A new distance measurement and its application in K-Means Algorithm

no code implementations10 Jun 2022 Yiqun Zhang, HouBiao Li

On the classical manifold learning datasets, S-curve and Swiss roll datasets, not only this new distance can cluster the data according to the structure of the data itself, but also the boundaries between categories are neat dividing lines.
