However, in these data-driven models used for forecasting monthly streamflow, the performances of filter-based feature selection (FFS) methods have not been studied in detail. In this study, we investigated the effectiveness of eight common FFS methods, namely, linear Pearson correlation, partial ...
CNN-based fusion methods are limited in capturing global information due to the CNN’s receptive field constraints. Fu et al. (2021) used attention module to fuse pixel level feature extracted form both channel and spatial dimension. CNN-based fusion techniques primarily focus on local feature ...
Feature selection methods based on minimum Redundancy Maximum Relevance (mRMR) filter and Ficher score were applied, each of them select a subset of features then the selection criteria is used to get the initial features subset. The second stage Support vector machine recursive feature elimination ...
Compared with other GA-based feature selection methods, HSMOGA has a much lower time complexity. According to experimental results, HSMOGA outperforms other nine state-of-art feature selection algorithms including five classic and four more recent algorithms in terms of kappa coefficient, accuracy, ...
feature space is impractical. Instead, more efficient strategies should be employed to explore the feature space in a way that ensures a reasonable solution can be found without evaluating every possible feature combination. Various feature selection methods have been developed based on different ...

This paper presents a new approach to feature selection, called CFS, (Correlation-based Feature Selection) that uses a correlation based heuristic to evaluate the worth of features. The e ectiveness of CFS is evaluated by comparing it with a well known wrapper feature selector that uses a ...
