Chapter 6 – Machine Learning in Anomaly Detection Systems
- What is an anomaly?
An anomaly is something that deviates from what is standard, normal, or expected.
- What is a Markov chain?
A Markov chain, or what we call a Markov process, is a stochastic model used for any random system that change its states according to fixed probabilities.
- What are Hidden Markov models?
The Hidden Markov Model is a Markov process where we are unable to directly observe the state of the system. Each state has a fixed probability of emitting. The main goal of an HMM model or classifier is assigning a label to a family of sequences, which means linking a sequence of observations to a sequence of labels.
- How can we detect anomalies with Hidden Markov models? ...
