Code for "Multi-Scale One-Class Recurrent Neural Networks for Discrete Event Sequence Anomaly Detection" @ SIGKDD2021

OC4Seq:

The OC4Seq repository contains code for a multi-scale one-class recurrent neural network for detecting anomalies in discrete event sequences. The method implemented here is described in this paper.

Usage

• exp.py: This is the main experiment script
• model.py: The OC4Seq is implemented in the this file
• trainer.py: It implements the training producedure
• utils.py: It preprocesses the data for experiment
