Experience-Based Evolutionary Algorithms for Expensive Optimization

1 code implementation9 Apr 2023 Xunzhao Yu, Yan Wang, Ling Zhu, Dimitar Filev, Xin Yao

Our experimental results on expensive multi-objective and constrained optimization problems demonstrate that experiences gained from related tasks are beneficial for the saving of evaluation budgets on the target problem.

Integrating features from lymph node stations for metastatic lymph node detection

no code implementations9 Jan 2023 Chaoyi Wu, Feng Chang, Xiao Su, Zhihan Wu, Yanfeng Wang, Ling Zhu, Ya zhang

The branch targets to solve a closely related task on the LN station level, i. e., classifying whether an LN station contains metastatic LN or not, so as to learn representations for LN stations.

A multi-objective optimization framework for on-line ridesharing systems

no code implementations7 Dec 2020 Hamed Javidi, Dan Simon, Ling Zhu, Yan Wang

The ultimate goal of ridesharing systems is to matchtravelers who do not have a vehicle with those travelers whowant to share their vehicle.

Hot and counter-rotating star-forming disk galaxies in IllustrisTNG and their real-world counterparts

no code implementations3 Nov 2020 Shengdong Lu, Dandan Xu, Yunchong Wang, Yanmei Chen, Ling Zhu, Shude Mao, Volker Springel, Jing Wang, Mark Vogelsberger, Lars Hernquist

A key feature of a large population of low-mass, late-type disk galaxies are star-forming disks with exponential light distributions.

Towards Interpretable-AI Policies Induction using Evolutionary Nonlinear Decision Trees for Discrete Action Systems

no code implementations20 Sep 2020 Yashesh Dhebar, Kalyanmoy Deb, Subramanya Nageshrao, Ling Zhu, Dimitar Filev

In this paper, we use a recently proposed nonlinear decision-tree (NLDT) approach to find a hierarchical set of control rules in an attempt to maximize the open-loop performance for approximating and explaining the pre-trained black-box DRL (oracle) agent using the labelled state-action dataset.

Unravelling stellar populations in the Andromeda Galaxy

no code implementations8 May 2020 Grzegorz Gajda, Ortwin Gerhard, Matías Blaña, Ling Zhu, Juntai Shen, Roberto P. Saglia, Ralf Bender

The formation of the bar lead to the re-arrangement of the [Z/H] distribution, causing a flat gradient along the bar.
