GARA: A novel approach to Improve Genetic Algorithms' Accuracy and Efficiency by Utilizing Relationships among Genes

no code implementations28 Apr 2024 Zhaoning Shi, Meng Xiang, Zhaoyang Hai, Xiabi Liu, Yan Pei

We design a directed multipartite graph encapsulating the solution space, called RGGR, where each node corresponds to a gene in the solution and the edge represents the relationship between adjacent nodes.

LCCo: Lending CLIP to Co-Segmentation

no code implementations22 Aug 2023 Xin Duan, Yan Yang, Liyuan Pan, Xiabi Liu

With a backbone segmentation network that independently processes each image from the set, we introduce semantics from CLIP into the backbone features, refining them in a coarse-to-fine manner with three key modules: i) an image set feature correspondence module, encoding global consistent semantic information of the image set; ii) a CLIP interaction module, using CLIP-mined common semantics of the image set to refine the backbone feature; iii) a CLIP regularization module, drawing CLIP towards this co-segmentation task, identifying the best CLIP semantic and using it to regularize the backbone feature.
