What can you use the app for?

Kaggle is a platform for data scientists to compete and earn prizes or cash for their insights. Additionally, companies can use Kaggle to have their sets of data interpreted by a vast number of data scientists and they can then select a winning prediction model that is the best one for them. Kaggle offers a win-win scenario for all parties involved. Companies start by establishing a predictive modeling or analytics competition. From there, data miners and statisticians worldwide can compete to produce the very bets models. Kaggle and this crowd-sourcing approach are ideal when it comes to predictive modeling since there are many different ways to come to a valid conclusion. Through Kaggle, companies can review these interpretations and then select the one that is the most accurate, compelling or useful for them. This is much less expensive than hiring on a data scientist full time and could lead to better results since an organization isn't having to rely upon a single person's evaluation or interpretation of the numbers for their future strategies. Also, competitors on Kaggle can team up to offer a more vast knowledge proposition to the companies or they can use Kaggle to interact with one another and get support or "expert" opinions on similar projects. Kaggle is a stat-geek's paradise.
