MATLAB for Machine Learning - Second Edition, By Giuseppe Ciaburro.

Anomaly Detection in MATLAB 

Throughout the life cycle of a physical system, the occurrence of failures or malfunctions poses a potential threat to its normal functioning. To safeguard against critical interruptions, it becomes imperative to implement an anomaly detection system within the facility. Termed as a fault diagnosis system, this mechanism is designed to identify potential malfunctions within the monitored system. The pursuit of fault detection stands as a pivotal and defining phase in maintenance interventions, demanding a systematic and deterministic approach to comprehensively analyze all conceivable causes that might have led to the malfunction. 

Anomaly detection overview 

Anomaly detection is a technique used in data analysis and ML to identify data points or patterns that deviate significantly from the expected or normal behavior within a dataset. Anomalies, also known as outliers, are data points that do not conform to most of the data and may indicate errors, fraud, unusual events, or other important information. Anomaly detection has various applications across different domains, such as cybersecurity, industrial quality control (QC), finance, healthcare, and more. 

We can start to get an overview of different types of anomalies to understand what is intended with this term, we will list some types of anomalies: 

Point anomalies: These are individual data points that are considered anomalies, such as a single fraudulent transaction in a credit card dataset. 

Contextual anomalies: These are anomalies that are context-dependent. A data point might not be an anomaly on its own but is unusual in a particular context or time, such as a sudden spike in web traffic during a holiday sale. 

Collective anomalies: These are anomalies that are identified by examining a group of data points collectively. These anomalies involve patterns or relationships between data points. 

There are several methods for addressing anomaly detection problems, ranging from simple statistical techniques to complex ML algorithms. The choice of method depends on the nature of the data and the specific problem you are trying to solve. Here, we are listing the most used ones: 

Statistical methods: Statistical techniques such as z-scores, percentiles, and boxplots can be used to identify anomalies based on deviations from the mean or median of the data distribution. 

ML: Supervised, unsupervised, and semi-supervised ML algorithms can be used for anomaly detection. Some popular methods include Isolation Forest, One-Class Support Vector Machine (One-Class SVM), autoencoders (AEs), and k-means clustering. 

Time series analysis: Specialized techniques are used for detecting anomalies in time series data, such as autoregressive (AR) models, exponential smoothing, and moving averages (MAs). 

Density estimation: Methods such as kernel density estimation (KDE) and Gaussian Mixture Models (GMMs) are used to estimate the probability density function of the data and identify anomalies as low-density regions. 

Deep learning (DL): Neural networks (NNs), especially deep AEs (DAEs) and recurrent NNs (RNNs), are used for anomaly detection in high-dimensional data or sequences. 

Ensemble methods: Combining multiple anomaly detection models can improve overall performance and robustness. 

In addressing anomaly detection problems, we have to face some challenges. For example, determining an appropriate threshold for defining anomalies can be challenging. Imbalanced datasets, where anomalies are rare, can make model training and evaluation tricky. Handling high-dimensional data and noisy datasets can also be challenging. 

Anomaly detection is a valuable tool for identifying rare but potentially important events or patterns in large datasets. The choice of method depends on the specific domain, data characteristics, and the nature of anomalies that need to be detected.
