This repository documents all my data science projects, where I explore different machine learning algorithms for predictive analytics. Built by Debby Ling
- Used RandomForestRegressor to predict the top 11 contestants of Produce 101 Season 2 to achieve accuracy of 82.9%, from 5 weeks of data.
"Produce 101 Season 2 (프로듀스 101 시즌 2) is a 2017 reality boy band survival show on Mnet.

- With Support Vector Machine, predicted with 99% accuracy whether a donor would donate blood in the subsequent month.
- Nature or nurture -- will the education level of parents influence that of their child? Is the education level of a father a greater determinant? Guardian and conventional wisdom affirms this. Using simple linear regression, I predict with 97% accuracy the results of students.
- With Artificial Neural Networks, predicted the state of wells in Tanzania using artificial neural networks and xgboost with a 70% accuracy.
- Nutella's change in recipe was a public relations disaster. Or was it? Although the news was first revealed on Facebook on 2 Nov, most of social media didn't quite react until a Daily Mail article was published on the 6th.
