Neural Anomaly Detection Using Keras -- Visual Studio Magazine

An advantage of using a neural technique compared to a standard clustering technique is that neural techniques can handle non-numeric data by encoding that data. Anomaly detection, also called outlier detection, is the process of finding rare items in a dataset. Examples include finding fraudulent login events and fake news items. Take a look at the demo program in Figure 1. The demo examines a 1,000-item subset of the well-known MNIST (modified National Institute of Standards and Technology) dataset.
