In evolutionary feature selection (EFS), that mapping consists in dropping off some of the features ( attributes ) from the original representation, so the dimensionality of the resulting representation space is not greater than that of the original space. In evolutionary feature construction (EFC),...
Integrating channel selection and feature selection in a real time epileptic seizure detection system. To address this problem, we propose a two stage seizure detection system which integrates off-line channel selection and feature selection before the construction of the final model. This system allows...
Feature selection is commonly employed for identifying collectively-predictive biomarkers and biosignatures; it facilitates the construction of small statistical models that are easier to verify, visualize, and comprehend while providing insight to the human expert. In this work we extend established constr...
The present study examines the role of feature selection methods in optimizing machine learning algorithms for predicting heart disease. The Cleveland Heart disease dataset with sixteen feature selection techniques in three categories of filter, wrapper, and evolutionary were used. Then seven algorithms Ba...
This paper describes the autofeat Python library, which provides a scikit-learn style linear regression model with automated feature engineering and selection capabilities. Complex non-linear machine learning models such as neural networks are in practic

For example, the tracked vehicle roadarm surface model discussed in Chapter 2 (Section 2.6.2) was created in B-spline surfaces, imported into SolidWorks, and then thickened for a solid model in support of structural analysis using FEA. Note that except for the construction features, geometric ...
Feature selection and radiomics score construction The intraclass correlation coefficient (ICC) value of each radiomics feature was calculated, and features with ICC values higher than 0.75 were considered reliable and stable and were retained. The least absolute shrinkage and selection operator (LASSO) ...
in single-cell data, especially in the context of noisy data that contain biological or technical challenges (e.g., low total mRNA count, low signal-to-noise ratio, or dropout). In this study, we compared DELVE to eleven other feature selection approaches and evaluated methods on their ...
we call such a step Features Selection. Next, she runs the quality methods using the general approach described in algorithm 1 and evaluates the results (namely, Experiment Execution). If the results are Extended Feature Models for Quality-Based ML Development 95 Data Scientist Features selection ...
