Adaptive Patching for High-resolution Image Segmentation with Transformers

no code implementations15 Apr 2024 Enzhi Zhang, Isaac Lyngaas, Peng Chen, Xiao Wang, Jun Igarashi, Yuankai Huo, Mohamed Wahib, Masaharu Munetomo

For high-resolution images, e. g. microscopic pathology images, the quadratic compute and memory cost prohibits the use of an attention-based model, if we are to use smaller patch sizes that are favorable in segmentation.

Accelerating the Evolutionary Algorithms by Gaussian Process Regression with $ε$-greedy acquisition function

no code implementations13 Oct 2022 Rui Zhong, Enzhi Zhang, Masaharu Munetomo

Based on this hypothesis, in each generation of optimization, we replace the worst individual in Evolutionary Algorithms (EAs) with the elite individual to participate in the evolution process.

Accelerating the Genetic Algorithm for Large-scale Traveling Salesman Problems by Cooperative Coevolutionary Pointer Network with Reinforcement Learning

no code implementations27 Sep 2022 Rui Zhong, Enzhi Zhang, Masaharu Munetomo

In this paper, we propose a two-stage optimization strategy for solving the Large-scale Traveling Salesman Problems (LSTSPs) named CCPNRL-GA. First, we hypothesize that the participation of a well-performed individual as an elite can accelerate the convergence of optimization.

Cooperative coevolutionary Modified Differential Evolution with Distance-based Selection for Large-Scale Optimization Problems in noisy environments through an automatic Random Grouping

no code implementations2 Sep 2022 Rui Zhong, Masaharu Munetomo

Simulation experiments and mathematical analysis show that aRG can detect the interactions between variables without the fitness landscape knowledge, and the sub-problems decomposed by aRG have smaller scales, which is easier for EAs to optimize.

Accelerating differential evolution algorithm with Gaussian sampling based on estimating the convergence points

no code implementations31 Aug 2022 Rui Zhong, Masaharu Munetomo

In this paper, we propose a simple strategy for estimating the convergence point approximately by averaging the elite sub-population.

Cooperative coevolutionary hybrid NSGA-II with Linkage Measurement Minimization for Large-scale Multi-objective optimization

no code implementations29 Aug 2022 Rui Zhong, Masaharu Munetomo

In the variable grouping stage, according to our previous research, we treat the variable grouping problem as a combinatorial optimization problem, and the linkage measurement function is designed based on linkage identification by the nonlinearity check on real code (LINC-R).
