Autoencoders are applied to many problems, including facial recognition, [5] feature detection, [6] anomaly detection, and learning the meaning of words. [7] [8] In terms of data synthesis, autoencoders can also be used to randomly generate new data that is similar to the input (training) data. [6]
ELKI is an open-source Java data mining toolkit that contains several anomaly detection algorithms, as well as index acceleration for them. PyOD is an open-source Python library developed specifically for anomaly detection. [56] scikit-learn is an open-source Python library that contains some algorithms for unsupervised anomaly detection.
Many variational autoencoders applications and extensions have been used to adapt the architecture to other domains and improve its performance. β {\displaystyle \beta } -VAE is an implementation with a weighted Kullback–Leibler divergence term to automatically discover and interpret factorised latent representations.
This is often achieved using autoencoders, which are a type of neural network architecture used for representation learning. Autoencoders consist of an encoder network that maps the input data to a lower-dimensional representation (latent space), and a decoder network that reconstructs the input from this representation.
Real-world use cases for Deeplearning4j include network intrusion detection and cybersecurity, fraud detection for the financial sector, [21] [22] anomaly detection in industries such as manufacturing, recommender systems in e-commerce and advertising, [23] and image recognition. [24]
In machine learning, normalization is a statistical technique with various applications. There are two main forms of normalization, namely data normalization and activation normalization.
Systems using artificial neural networks have been used to great effect. Another method is to define what normal usage of the system comprises using a strict mathematical model, and flag any deviation from this as an attack. This is known as strict anomaly detection. [3]
