Air Quality Index (AQI) across stations and cities in India from 2015 to 2020

---

I have taken an AQI dataset from Kaggle and performed some EDA on it as well as implemented a decision tree classiifer to classify the air quality into one of the six buckets:

1. Good
2. Moderate
3. Satisfactory
4. Poor
5. Very Poor
6. Severe

• The dataset is taken from Kaggle.
• It contains air quality data and AQI (Air Quality Index) at hourly and daily level of various stations across multiple cities in India from 2015 to 2020.
• For this particular project, I have used just a part of the datasets provided in Kaggle, which contains day-wise city air pollution data.

Libraries used:

1. Numpy
2. Pandas
3. Seaborn
4. Chart Studio
5. Plotly
6. Pandas Profiling
7. PyCaret

I have used Pandas Profiling for performing exploratory data analysis and PyCaret for performing the machine learning classification task. Below are their installation commands:

For Pandas Profiling:

pip install pandas-profiling[notebook]

or

pip install https://github.com/pandas-profiling/pandas-profiling/archive/master.zip

or

conda install -c conda-forge pandas-profiling

For PyCaret:

#create a conda environment
conda create --name yourenvname python=3.6

#activate environment
conda activate yourenvname

#install pycaret
pip install pycaret

#create notebook kernel connected with the conda environment
python -m ipykernel install --user --name yourenvname --display-name "display-name"

* Some EDA

1. Dataframe

2. AQI bucket chart

3. Pearson's correlations

4. Most polluted cities

5. Least polluted cities

6. City wise pollutants analysis

where BTX = Benzene + Toluene + Xylene

7. Yearly analysis

* Classification model used: Decision tree

I have used 'decision tree' as a classification model for this prediction problem based on the following results:

Using decision tree for classification, confusion matrix for validation data:
