基于协方差矩阵自适应演化策略(CMA-ES)的高效特征选择 特征选择是指从原始特征集中选择一部分特征,以提高模型性能、减少计算开销或改善模型的解释性。特征选择的目标是找到对目标变量预测最具信息量的特征,同时减少不必要的特征。这有助于防止过拟合、提高模型的泛化能力,并且可以减少训练和推理的计算成本。 如果特征N...
Code for the paper "Learning Step-Size Adaptation in CMA-ES" License Our work is available under Apache-2.0. In order to learn step-size adaptation in CMA-ES we use guided policy search (GPS). We built upon the GPS version as given by Li and Malik. The original GPS code of Li and...
My code so far: CONTROLLER MODEL:...MongoDB save same data repeatedly I have many number of documents in my collection i want to save same data by changing only one field i.e. "date" (which will be current time) repeatedly in the Mongo database.so how can i do......
This coupling performed in two phases is based on the combination of two codes: This is the HySubF-FEM code ( Hy drodynamic of Sub surface F low by F inite E lement M ethod) used for the first phase allowing the calculation of the flow and the CMA-ES code ( C ovariance M atrix...
