- W4239174087 abstract "The advent of Big Data, and specially the advent of datasets with high dimensionality, has brought an important necessity to identify the relevant features of the data. In this scenario, the importance of feature selection is beyond doubt and different methods have been developed, although researchers do not agree on which one is the best method for any given setting. This chapter provides the reader with the foundations about feature selection (see Sect. 2.1) as well as a description of the state-of-the-art feature selection methods (Sect. 2.2). Then, these methods will be analyzed on several synthetic datasets (Sect. 2.3) trying to draw conclusions about their performance when dealing with a crescent number of irrelevant features, noise in the data, redundancy and interaction between attributes, as well as a small ratio between number of samples and number of features. Finally, in Sect. 2.4, some state-of-the-art methods will be analyzed to study their scalability, i.e. the impact of an increase in the training set on the computational performance of an algorithm in terms of accuracy, training time and stability." @default.
