Anomaly detection (or Outlier analysis) is the identification of items, events or observations which do not conform to an expected pattern or other items in a dataset. It is used is applications such as intrusion detection, fraud detection, fault detection and monitoring processes in various domains including energy, healthcare and finance.
In this workshop, we will discuss the core techniques in anomaly detection and discuss advances in Big Data and Deep Learning in this field.
Through case studies, we will discuss how anomaly detection techniques could be applied to various business problems including stock data analysis, fraud detection, credi risk etc.. We will also demonstrate, using R, Python, Apache Spark, Keras and Tensorflow applications to help reinforce concepts in anomaly detection and best practices in analyzing and reviewing results.
Data science techniques using supervised and unsupervised machine learning techniques are becoming increasing popular in identifying patterns in data and to build systems that can better predict the future. With increase in volume, variety and velocity of data, many big data techniques are being used to scale these techniques today.
However, Anomaly detection techniques focus on detecting the asymetric outliers in the data sets. Many techniques are used for anomaly detection and a comprehensive understanding of these techniques would help get a better understanding of the nature of the data and to detect and act upon these outliers.
What you will learn
In this workshop, you will learn the core techniques used in Anomaly detection. Through examples in R, Python and Apache Spark,Keras and Tensorflow you will learn how to methodically apply various anomaly techniques. In addition, you will learn
