Quora is a platform that empowers people to learn from each other. On Quora, people can ask questions and connect with others who contribute unique insights and quality answers. A key challenge is to weed out insincere questions which are those founded upon false premises, or that intend to make a statement rather than look for helpful answers. In this project we will develop models that identify and flag insincere questions.
A model to predict children's Genetic disorders with the Disorder subclass. The aim is to identify a reliable model for the genetic diagnosis using machine learning. In this project, to obtain good results, it was essential to work with the missing data where MICE was used, an imputation method which allowed working with a considerable number of empty values in the features of interest.
The goal of the Project (and competition) is to predict seven different cover types in four different wilderness areas of the Roosevelt National Forest of Northern Colorado with the best accuracy.
Kaggle is challenging you to build a model that predicts the total ride duration of taxi trips in New York City. This project was very interesting from the point of view of working with cluster to incorporate new features to the model as well as additional databases with the same purpose.
