Credit card fraud detection can be viewed as Streaming Data Analysis in which a card is used in real time and the detection must be done immediately. This requires a real time analysis that is faster than the batch analysis. The method of extracting and analyzing only the core part of the data will satisfy the requirements of this computation speed. This has been done through techniques such as principal component analysis. In this paper, we propose a method that applies data mining techniques after reducing the dimension of data by preprocessing the data with Autoencoder. This method is known as the dimension reduction method and it uses a Neural Network. Autoencoder is a very efficient method of dimension reduction because it can capture nonlinear associations between data feature dimensions. We also propose a methodology to combine Autoencoder with CQL for fraud detection analysis in the database.
