Tracking Players in a Badminton Court by Two Cameras

no code implementations9 Aug 2023 Young-Ching Chou, Shen-Ru Zhang, Bo-Wei Chen, Hong-Qi Chen, Cheng-Kuan Lin, Yu-Chee Tseng

We leverage two off-the-shelf cameras, one on the top of the court and the other on the side of the court.

Multi-Object Tracking

A hybrid model for predicting human physical activity status from lifelogging data

no code implementations26 May 2019 Ji Ni, Bo-Wei Chen, Nigel M. Allinson, Xujiong Ye

We validate the model with the real data collected from a group of participants in the UK, and compare it with other popular two-stage hybrid models.

Incorporating prior financial domain knowledge into neural networks for implied volatility surface prediction

no code implementations29 Apr 2019 Yu Zheng, Yongxin Yang, Bo-Wei Chen

This is one of the very first studies which discuss a methodological framework that incorporates prior financial domain knowledge into neural network architecture design and model training.

Recursion-Free Online Multiple Incremental/Decremental Analysis Based on Ridge Support Vector Learning

no code implementations1 Aug 2016 Bo-Wei Chen

This study presents a rapid multiple incremental and decremental mechanism based on Weight-Error Curves (WECs) for support-vector analysis.

Efficient Multiple Incremental Computation for Kernel Ridge Regression with Bayesian Uncertainty Modeling

no code implementations1 Aug 2016 Bo-Wei Chen, Nik Nailah Binti Abdullah, Sangoh Park

This study presents an efficient incremental/decremental approach for big streams based on Kernel Ridge Regression (KRR), a frequently used data analysis in cloud centers.

Privacy-Preserved Big Data Analysis Based on Asymmetric Imputation Kernels and Multiside Similarities

no code implementations25 Mar 2016 Bo-Wei Chen

To deal with these incomplete data, a new kernel function with asymmetric intrinsic mappings is proposed in this study.

Efficient Divide-And-Conquer Classification Based on Feature-Space Decomposition

no code implementations29 Jan 2015 Qi Guo, Bo-Wei Chen, Feng Jiang, Xiangyang Ji, Sun-Yuan Kung

Firstly, we divide the feature space into several subspaces using the decomposition method proposed in this paper.

A dynamic pricing model for unifying programmatic guarantee and real-time bidding in display advertising

no code implementations20 May 2014 Bo-Wei Chen, Shuai Yuan, Jun Wang

From the experiments we find that, in a less competitive market, lower prices of the guaranteed contracts will encourage the purchase in advance and the revenue gain is mainly contributed by the increased competition in future RTB.
