Deep learning models for anomaly detection

[Expired]

Introduction

Anomaly detection is the task of automatically determining instances that are dissimilar to others considered as normals. Such instances are called anomalies, as they do not conform to the training data distribution [1]. Automatic detection of anomalies allows users to save time examining lots of normal cases in order to find outliers and finds application in several fields, such as surveillance and medicine. Different kinds of deep learning models have been introduced to solve this task. Recently, a new architecture based on deep learning  for anomaly detection in the context of industrial control systems has been proposed [2]. Other approaches rely on attention mechanisms [3]  or propose architectures based on Transformers [4]  to highlight the anomalies.

The goal of this thesis is to study recently proposed models for detection of anomalous instances and  to apply them to an industrial problem.
