Introduction to Feature Selection - MATLAB & Simulink - MathWorks
: Start with the function keyword, define outputs, and ensure the filename matches the function name. Example : matlab-2017
In MATLAB, features are usually calculated within functions that take raw data as input and return a single value or vector. Introduction to Feature Selection - MATLAB & Simulink
: You can use functions like gencfeatures to perform automated feature engineering if your data is in a table. In MATLAB R2017 (both and R2017b ), "writing
function featureValue = getMeanAmplitude(signal) % This function calculates a simple statistical feature featureValue = mean(abs(signal)); end Use code with caution. Copied to clipboard 2. Feature Engineering Workflow
: After writing several feature functions, you can use algorithms like Sequential Feature Selection to identify which ones are most predictive.
In MATLAB R2017 (both and R2017b ), "writing a feature" typically refers to feature engineering for machine learning or signal processing, or creating a custom function to extract specific data characteristics. 1. Defining a Feature Extraction Function
