Objective Our goal is to train a Neural Network to detect fraudulent credit card transactions in a dataset referring to two days transactions by european cardholders. Source: https://www.kaggle.com/mlg-ulb/creditcardfraud/data Data credit = read.csv(path) The datasets contains transactions made by credit cards in September 2013 by european cardholders. This dataset presents transactions that occurred in two days. As we can see, this dataset consists of thirty explanatory variables, and a response variable which represents whether a transation was a fraud or not.
Random Forest In this post we will explore some ideas around the Random Forest model Objective We are working on in the dataset called Boston Housing and the main idea here is regression task and we are concerned with modeling the price of houses in thousands of dollars in the Surburb of Boston. So, we are dirting our hands in a regression predictive modeling problem. The main goal here is to fit a regression model that best explains the variation in medv variable.
