The field of anomaly detection and generation is moving towards leveraging advanced deep learning techniques, such as diffusion models and variational autoencoders, to improve the detection of novel and rare attacks. Researchers are exploring the use of generative models to address the issue of class imbalance in network traffic data, which is a common challenge in network intrusion detection systems. Furthermore, there is a growing interest in using unsupervised learning methods, such as deep clustering and autoencoders, to identify anomalies in complex datasets. These approaches have shown promising results in improving the accuracy and efficiency of anomaly detection systems. Noteworthy papers include:

• C2BNVAE, which proposes a dual-conditional deep generation approach for network traffic data.
• Anomaly Detection and Generation with Diffusion Models: A Survey, which provides a comprehensive review of anomaly detection and generation with diffusion models.
• Unsupervised Deep Clustering of MNIST with Triplet-Enhanced Convolutional Autoencoders, which implements an advanced unsupervised clustering system for MNIST handwritten digits.
