Linear Regression vs. Decision Trees: Handling Outliers

In regression tasks, it's often assumed that decision trees are more robust to outliers than linear regression. See this Quora question for a typical example. I believe this is also mentioned in the book "Introduction to Statistical Learning", which may be the source of the notion. Predictions from a decision tree are based on the… Continue reading Linear Regression vs. Decision Trees: Handling Outliers

Lead Scoring with Customer Data Using glmnet in R

Lead Scoring Lead scoring is an important task for business. Lead scoring is identifying which individuals in a population may convert (purchase) if marketed to, or assigning them a probability of converting, or determining how much value that individual may have as a customer. Properly using data to support this task can greatly benefit your… Continue reading Lead Scoring with Customer Data Using glmnet in R

Deep Neural Networks: CS231n & Transfer Learning

Deep learning (also known as neural networks) has become a very powerful technique for dealing with very high dimensional data, i.e. images, audio, and video. As one example, automated image classification has become highly effective. This task consists of putting an image into one of a certain number of classes. Look at the results of… Continue reading Deep Neural Networks: CS231n & Transfer Learning
