ClimateWins Machine Learning Solutions

Project Overview

ClimateWins, a fictional European nonprofit organization, leverages machine learning to predict the consequences of climate change. As an analyst for ClimateWins, it is crucial to rely on data-driven insights to evaluate tools that categorize and predict weather patterns across mainland Europe.

The organization is concerned with the increase in extreme weather events, particularly over the past 10 to 20 years. Utilizing data from the past century, we aim to use machine learning to find new patterns in weather changes, predict the consequences of climate change around Europe, and identify safe places to live in Europe.

Key Findings From Algorithm Exploration

Hierarchical Clustering & PCA

  • Using the Dendrogram Ward method, combined with PCA to reduce variables from 147 to 2, results in more well-defined clusters.

  • Two clusters were created with a threshold value of 150 and plotted on the chart to compare with data from two weather stations. The results show that the clusters effectively represent Pleasant and Not Pleasant weather conditions.

Random Forests

  • The random forest model yielded an accuracy score of 0.60 for all weather stations and 1.0 for individual weather stations.

  • The variable importance charts identify the top influential weather stations (Düsseldorf, Maastricht, and Basel) and the most influential weather observations (precipitation, maximum temperature, and global radiation).

CNN with Bayesian Optimization

  • The CNN with Bayesian Optimization has significantly improve the accuracy score to 0.7954 and reduce loss to 0.5482
