[2002 08519] Pulsars Detection by Machine Learning

It is an active topic to investigate the schemes based on machine learning (ML) methods for detecting pulsars as the data volume growing exponentially in modern surveys To improve the detection performance input features into an ML model should be investigated specifically In the existing pulsar detection researches based on ML methods there are mainly two kinds of feature designs: the

Feature Selection For Machine Learning in Python

Recursive Feature Elimination or RFE for short is a popular feature selection algorithm RFE is popular because it is easy to configure and use and because it is effective at selecting those features (columns) in a training dataset that are more or most relevant in predicting the target variable There are two important configuration options when using RFE: the choice in the
