A brief description of the selected dataset and the task to be solved:

Dataset: “Combined-wine”

Link: https://www.kaggle.com/datasets/siyuanh/combined-wine-data

Two datasets were created, using red and white wine samples. The inputs include objective tests (e.g. PH values) and the output is based on sensory data.

Task: classification. According to the data on the content of several data mining methods were applied to model these datasets under a regression approach. The support vector machine model achieved the best results.

Description of the results achieved:

Training the 3 classification models and using linear classifier with results metrics(f1-score=0.99), the support vector machine with results metrics(f1-score =0.99 ) and decision tree with results metrics(f1-score = 1 ). The model trained using the decision tree showed the best quality.

Description of the progress of the case task:

Stages of the project:

• loading the dataset;
• studying the dataset;
• data cleaning;
• training of classification models;
• evaluation of the quality of trained classification models;
• choosing the best model.

Description of deviations and difficulties encountered during the task, as well as the ways used to overcome them: In the task we have incorrect values were found in the dataset ("#NUM!" where the numbers should be). Rows with incorrect values have been deleted from the dataset.

Conclusions on the work done.

In the project, we realized the selected 3 classification models which of trained, and get the best one with using quality metrics.
