Portfolio Recommender is a web application that helps compannies to find leads that match their portfolio's characteristics. The company must insert a list with it's clients ids and the app will return a list with similar clients found in the market.

This is my proposed solution for the Codenation Data Science Challenge to enter the AceleraDev program. In this project, we had to predict the math grades of students who took the Brasilian National Exam (ENEM), using the other subjects grades to build up a model. Instead of building one model, I built 6 different models and compared their results to see which one of them could make the best predictions. [python] [ML]

It's very common to see a 2D visual explanation of how the k-means algorithm works, but did you know you could make it in 3D? In this experiment I combined 3d visualization with k-means clustering. At the end of the project I show a video made with the plot of each iteration runned by the algorithm. [python]
