ML-Olympiad Water-Quality-Prediction

 

Introduction

Greetings everyone, I am excited to share my journey participating in the water quality estimation competition. 

The competition required us to build a machine learning model based on the training data provided and predict the water quality estimation for the test dataset accurately. I put my knowledge of machine learning and data analysis into practice to preprocess, analyze, and visualize the data. I explored various regression techniques and hyperparameters to find the best model for this task. After numerous iterations, I was able to build a model that achieved high accuracy in predicting the water quality estimation for the test dataset. 

My hard work and dedication paid off as I secured the 18th position in the competition. I am sharing the code I used for this prediction task (regression) below, hoping that it can help and inspire others to pursue their interests in machine learning.

Machine Learning Models

I utilized three different machine learning models to predict the quality estimation for the test dataset. These models were the Sequential Neural Network, the XGBoost Regressor, and the Random Forest Regressor. 

Through rigorous experimentation and testing, I found that the XGBoost Regressor and the Random Forest Regressor performed the best in terms of prediction accuracy. 

Both models outperformed the Sequential Neural Network in this task, which is a reasonable outcome given the nature of the data. 

The XGBoost Regressor and the Random Forest Regressor are both tree-based models that excel in handling tabular data with multiple levels of categorical data. These models can capture complex interactions between variables, making them particularly well-suited for this type of problem. Ultimately, the XGBoost Regressor had the best performance based on the RMSE metric, followed closely by the Random Forest Regressor. 

Conclusion

I believe that the combination of these two models can provide a robust solution for similar regression problems in the future.

I would like to extend an invitation to try your own model and submit a late entry for the water quality estimation competition. This is an excellent opportunity to put your skills to the test and see how well your model performs against others in the competition. The competition data and rules are still available, so don't hesitate to give it a shot. You might be surprised at how well your model performs. Plus, this competition is an excellent opportunity to learn new techniques, explore new algorithms, and build your portfolio. 

So, why not take a shot and see how your model stacks up against others? Good luck, and happy modeling!
