Optimal Classification Based Anomaly Detection With Neural Networks A binary classification problem of “normal” vs. “anomaly”. we will show that solving the classification problem can, in turn, solve the level set estimation problem. Overall, our work provides the first theoretical guarantees of unsupervised neural network based anomaly detectors and empirical insights on how to design them well.
Anomaly Detection We develop the first theoretically grounded neural network based approach for unsupervised anomaly detection. transforming anomaly detection into a binary classification problem via density level set estimation, we train neural networks with supervision from synthetic anomalies.

Optimal classification based anomaly detection with neural networks: theory and practice this contains the code for our theoretically grounded neural network for anomaly detection. We propose a one class neural network (oc nn) model to detect anomalies in complex data sets. oc nn combines the ability of deep networks to extract progressively rich representation of data with the one class objective of creating a tight envelope around normal data.

The paper provides a theoretical analysis of the optimal classification based anomaly detection problem and then presents a practical neural network based solution. In the classification stage, a neural network algorithm was used to train and classify the dataset. the experimental results showed a detection accuracy of 79.81% for the first dataset with about 16 features, which excluded some common attacks. Overall, our work provides the first theoretical guarantees of unsupervised neural network based anomaly detectors and empirical insights on how to design them well. The proposed model utilizes random forest (rf) for feature extraction, which employs two distinct target importance analyses: 1. class imbalance, and 2. class weights. in phase 1, an artificial neural network and an improved tabnet model were utilised for classifying three classes: normal, suspect, and pathology (nsp), with smote balancing.
