Analyze Data by Training a Linear Regression model for House Price Prediction

This workflow is an example of how to train a basic machine learning model - Linear Regression for a house price prediction task


If you want to give your acquired knowledge a test run, take a look at the Just KNIME It challenges. (Just KNIME It Link provided in External resources section of this workflow)
