Fraud Detection Using Deep Learning

Deep Learning has shown superior performance in the areas of image processing, object recognition and text processing. In this talk, I will present how Deep Learning can help with payment fraud detection. I will present results from experiments conducted on a very large data set containing over 10 million examples and 1000s of features. I will also explore several advanced features such as adaptive learning rate and dropout regularization and their impact on runtime and predictive performance.
