Hybrid gene selection approach using XGBoost and multi-objective genetic algorithm for cancer classification
Xiongshi Deng, Min Li, Shaobo Deng +1
Microarray gene expression data are often accompanied by a large number of genes and a small number of samples. However, only a few of these genes are relevant to cancer, resulting…
RFCBF: enhance the performance and stability of Fast Correlation-Based Filter
Xiongshi Deng, Min Li, Lei Wang +1
Feature selection is a preprocessing step which plays a crucial role in the domain of machine learning and data mining. Feature selection methods have been shown to be effctive in…
Breather transition dynamics, Peregrine combs/walls and modulation instability in a variable-coefficient nonlinear Schrödinger equation with higher-order effects
Lei Wang, Jian-Hui Zhang, Chong Liu +2
We study a variable-coefficient nonlinear Schrödinger (vc-NLS) equation with higher-order effects. We show that the breather solution can be converted into four types of nonlinear…
Stationary nonlinear waves, superposition modes and modulational instability characteristics in the AB system
Lei Wang, Zi-Qi Wang, Jian-Hui Zhang +2
We study the AB system describing marginally unstable baroclinic wave packets in geophysical fluids and also ultra-short pulses in nonlinear optics. We show that the breather can b…
