Fraud detection has a large imbalance between the number of valid vs fraudulent transactions which makes the traditional supervised machine learning approaches less capable. As we saw, autoencoders have two parts: an encoder network that reduces the dimensions of the input data, and a decoder network that aims to reconstruct the input. Fig. There are many available deep learning techniques, each with their strengths and weaknesses. Now, in this tutorial, I explain how to create a deep learning neural network for anomaly detection using Keras and TensorFlow. Why applying anomaly detection on Mars . The input–output relationship is not unique. 38 Collaborators built an anomaly detection model for identifying past or present extraterrestrial technology on the surface of Mars.
