Features by Score Ranking:
  • alcohol - 0.181394
  • density - 0.106549
  • pH - 0.082567
  • residual sugar - 0.082223
  • free sulfur dioxide - 0.081671
  • chlorides - 0.081378
  • volatile acidity - 0.080156
  • total sulfur dioxide - 0.078256
  • citric acid - 0.074874
  • fixed acidity - 0.071705
Target Value:
  • Quality - Fair and Very Good
Methods:
  • Training size : 0.7
  • Deep Learning Model: Sequential
Summary:
  • In data exploration and modeling, we utilize all features to predict the quality of wine. We perform deep learning sequential method to achieve 77.3 % accuracy rate.
  • There are two possible predicted classes: "Fair" and "Very Good". If we were predicting the quality of wine, "Very Good" would mean to have better quality, and "Fair" would mean to lower quality of wine.
  • The classifier made a total of 357 predictions.
  • Out of those 357 cases, the classifier predicted "Very Good" 2 times, and "Fair" 355 times.
  • In reality, 77 cases in the sample are in category of very good quality, 280 cases are not.



Top Five Features
dl_white_cm_selected

Summary:
  • In data exploration and modeling, we perform importance features methods to select the top five features to predict the quality of the wine. We perform a deep learning sequential method to achieve an 81.8 % accuracy rate. In comparing to the result with all features given, we are able to improve the accuracy rate by eliminating the unnecessary features.
  • There are two possible predicted classes: "Fair" and "Very Good". If we were predicting the quality of wine, "Very Good" would mean to have better quality, and "Fair" would mean to lower quality of wine.
  • The classifier made a total of 357 predictions.
  • Out of those 357 cases, the classifier predicted "Very Good" 13 times, and "Fair" 344 times.
  • In reality, 67 cases in the sample are in category of very good quality, 290 cases are not.

Top Five Features
dl_red_cm_selected

Summary:
  • In data exploration and modeling, we perform importanace features methods to select the top five features to predict the quality of wine. We perform a deep learning sequential method to achieve an 88.6 % accuracy rate. As a result, the accuracy rate has been slightly dropping by eliminating some of the features.
  • There are two possible predicted classes: "Fair" and "Very Good". If we were predicting the quality of wine, "Very Good" would mean to have better quality, and "Fair" would mean to lower quality of wine.
  • The classifier made a total of 123 predictions.
  • Out of those 123 cases, the classifier predicted "Very Good" 0 times, and "Fair" 123 times.
  • In reality, 18 cases in the sample are in category of very good quality, 105 cases are not.
