Common spatial pattern
Common spatial pattern (CSP) is a supervised signal processing method that computes spatial filters separating two classes of multichannel signals, used mainly in motor-imagery brain–computer interfaces.
Feature (machine learning)
A feature in machine learning is an input variable, also called a dimension, used to generate predictions, with feature engineering transforming raw data into useful form.
Feature engineering
Feature engineering is the use of domain knowledge to create features, the input variables machine learning algorithms work on, aiming for a minimal subset that preserves predictive performance.
Feature scaling
Feature scaling is a machine learning preprocessing step that rescales the numeric features of a dataset to comparable ranges, such as zero mean and unit variance, before training a model.
Feature selection
Feature selection, also called variable or input selection, chooses a subset of a dataset's variables for a machine learning model to improve prediction and reduce overfitting.
Sparse Bayesian learning
Sparse Bayesian learning is a Bayesian machine learning method that fits regression and classification models by pruning irrelevant basis functions, producing sparse models with probabilistic outputs.
