To demonstrate these various techniques, I've trained a number of models on the UCI Wine Quality dataset where I've generated my target by asserting that observations with a quality rating less than or equal to 4 are "low quality" wine and observations with a quality rating greater than or equal to 5 are "high quality" wine. A Chinese rice wine—Shaoxing—was among the wines served to Chinese President Xi Jinping on Sept. 25, 2015. It was the first Chinese wine ever served at a state dinner. The dataset used is Wine Quality Data set from UCI Machine Learning Repository. Input variables are fixed acidity, volatile acidity, citric acid, residual sugar We are splitting our dataset in a way such that all of the wine qualities are represented proportionally equally in both training and testing dataset.
