Simplex Search Based Brain Storm Optimization
Wei Chen, YingYing Cao, Shi Cheng +3
Through modeling human's brainstorming process, the brain storm optimization (BSO) algorithm has become a promising population-based evolutionary algorithm. However, BSO is pointed…
Active Expansion Sampling for Learning Feasible Domains in an Unbounded Input Space
Wei Chen, Mark Fuge
Many engineering problems require identifying feasible domains under implicit constraints. One example is finding acceptable car body styling designs based on constraints like aest…
Improving Regret Bounds for Combinatorial Semi-Bandits with Probabilistically Triggered Arms and Its Applications
Qinshi Wang, Wei Chen
We study combinatorial multi-armed bandit with probabilistically triggered arms (CMAB-T) and semi-bandit feedback. We resolve a serious issue in the prior CMAB-T studies where the…
Complete Submodularity Characterization in the Comparative Independent Cascade Model
Wei Chen, Hanrui Zhang
We study the propagation of comparative ideas or items in social networks. A full characterization for submodularity in the comparative independent cascade (Com-IC) model of two-id…
