Socialized Learning: A Survey of the Paradigm Shift for Edge Intelligence in Networked Systems

no code implementations20 Apr 2024 Xiaofei Wang, Yunfeng Zhao, Chao Qiu, QinGhua Hu, Victor C. M. Leung

In response to these issues, this paper introduces socialized learning (SL) as a promising solution, further propelling the advancement of EI.

Calibration-compatible Listwise Distillation of Privileged Features for CTR Prediction

no code implementations14 Dec 2023 Xiaoqiang Gui, Yueyao Cheng, Xiang-Rong Sheng, Yunfeng Zhao, Guoxian Yu, Shuguang Han, Yuning Jiang, Jian Xu, Bo Zheng

A typical practice is privileged features distillation (PFD): train a teacher model using all features (including privileged ones) and then distill the knowledge from the teacher model using a student model (excluding the privileged features), which is then employed for online serving.

Entire Space Cascade Delayed Feedback Modeling for Effective Conversion Rate Prediction

no code implementations9 Aug 2023 Yunfeng Zhao, Xu Yan, Xiaoqiang Gui, Shuguang Han, Xiang-Rong Sheng, Guoxian Yu, Jufeng Chen, Zhao Xu, Bo Zheng

Furthermore, there is delayed feedback in both conversion and refund events and they are sequentially dependent, named cascade delayed feedback (CDF), which significantly harms data freshness for model training.

Representing Camera Response Function by a Single Latent Variable and Fully Connected Neural Network

1 code implementation8 Sep 2022 Yunfeng Zhao, Stuart Ferguson, Huiyu Zhou, Karen Rafferty

In this paper, a new high-performance camera response model that uses a single latent variable and fully connected neural network is proposed.

Colour alignment for relative colour constancy via non-standard references

no code implementations30 Dec 2021 Yunfeng Zhao, Stuart Ferguson, Huiyu Zhou, Chris Elliott, Karen Rafferty

This makes it hard to achieve consistent colour assessment across a range of devices, and that undermines the performance of computer vision algorithms.

Few-Shot Partial-Label Learning

no code implementations2 Jun 2021 Yunfeng Zhao, Guoxian Yu, Lei Liu, Zhongmin Yan, Lizhen Cui, Carlotta Domeniconi

Partial-label learning (PLL) generally focuses on inducing a noise-tolerant multi-class classifier by training on overly-annotated samples, each of which is annotated with a set of labels, but only one is the valid label.

Spectral Illumination Correction: Achieving Relative Color Constancy Under the Spectral Domain

1 code implementation 2018 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT) 2018 Yunfeng Zhao, Huiyu Zhou, Chris Elliott, Karen Rafferty

Achieving color constancy between and within images, i. e., minimizing the color difference between the same object imaged under nonuniform and varied illuminations is crucial for computer vision tasks such as colorimetric analysis and object recognition.
