# Majority Voting Based Multi-Task Clustering of Air Quality Monitoring Network in Turkey
## 4 Multi-task Clustering
With this study, the following benefits can be obtained:

* Similar regions can be detected easily so that similar air quality management strategies can be applied for them by the decision-making authority. * Collecting similar information together and summarizing common features help environmental scientists figure out the present situation more clearly. * Data analysis becomes easier due to dealing with only few cluster instances instead of whole environmental data. * Data summarization is performed resulting in compact and useful information, thus one does not need to handle huge amounts of redundant data. * It can be used as a pre-processing step before performing the essential environmental study. * Inherent hidden patterns of air quality data can be discovered. * In the case of a new station to be classified, the process can be achieved by placing the station into the cluster that has the nearest cluster center. In the future, other unsupervised learning methods such as association rule mining or outlier detection or time series analysis can be applied on Turkey's air pollution data. Instead of using only pollutant levels, meteorological factors such as temperature, humidity, wind speed and direction, pressure, etc. are going to be added into the problem domain because they can significantly influence the air quality level of a region. Seasonal changes can also be observed instead of using yearly data. The severity of air quality may be clustered based on the impact on the health issue or the potential damage to the environment. Furthermore, a new study could be conducted to investigate the main causes of pollution by utilizing data such as fuel, exhaust and industrial waste. PM\({}_{2.5}\) is one of the most dangerous particulate matters. However, in Turkey, there is a missing data problem considering the measurements of PM\({}_{2.5}\) particulate matter. The same case is also valid for CO pollution, thus it is not dealt with in this study. If the study is extended to be applied on other countries, new air pollutants can also be handled.
