Examples of Kaggle

Walmart Sales Forecasting: In 2014, Walmart organized a Machine Learning competition on Kaggle to improve their sales forecasting accuracy. Participants were challenged to predict the future sales of Walmart stores across different departments, taking into account factors such as holidays, promotions, and seasonal trends.

Titanic: Machine Learning from Disaster: One of the most famous Kaggle competitions is the Titanic challenge, where participants are tasked with predicting the likelihood of passengers surviving the tragic event based on various features such as age, gender, and ticket class. This competition has served as an introductory project for many aspiring data scientists to learn critical machine learning techniques and tools.

Understanding Molecular Properties for Drug Discovery: In collaboration with Stanford University, Kaggle hosted a competition in 2012 called the “Predicting Biological Response” challenge. This competition aimed to predict the biological response of molecules based on their molecular properties, thus enabling the development of more effective drugs. The provided dataset included 3,793 molecules, and participants used various machine learning models and algorithms to make predictions that could significantly improve and accelerate the drug discovery process.
