## 🕵️ Introduction

Wine a little, laugh a lot and enjoy this challenge. The secret to a quality of wine is not only in it's smell ! let’s take a trip to north portugal .

We give you features of white vinho verde wine, you have to predict the quality of the wine.

Understand with code! Here is getting started code for you.😄

## 💾 Dataset

The dataset is related to white vinho verde wine of the Portugal. For more details, consult: Web Link or the reference [Cortez et al., 2009]. Due to privacy and logistic issues, only physicochemical (inputs) and sensory (the output) variables are available (e.g. there is no data about grape types, wine brand, wine selling price, etc.)

 Index Attribute 1 fixed acidity 2 volatile acidity 3 citric acid 4 residual sugar 5 chlorides 6 free sulfur dioxide 7 total sulfur dioxide 8 density 9 pH 10 sulphates 11 alcohol 12 quality (score between 0 and 10)

For simplification, attributes have been stored in csv file which has 12 columns, the last column is the quality rating and the rest 11 contain the features of the wine sample.

## 📁 Files

Following files are available in the resources section:

• train.csv - (3918 samples) This csv file contains the attributes describing the wine along with the wine quality.

• test.csv - (980 samples) File that will be used for actual evaluation for the leaderboard score but does not have the value denoting the wine quality.

## 🚀 Submission

• Prepare a csv containing header as quality and predicted value as ratings of the wine quality from [0-10].
• The file should be named as submission.csv.
• Sample submission format available at sample_submission.csv.

Make your first submission here 🚀 !!

## 🖊 Evaluation Criteria

During evaluation F1 score will be used to test the efficiency of the model where,

$F1 = 2 * \frac{precision*recall}{precision+recall}$
