Outlier Detection DataSets (ODDS)

In ODDS, we openly provide access to a large collection of outlier detection datasets with ground truth (if available). Our focus is to provide datasets from different domains and present them under a single umbrella for the research community. As such, we arrange the datasets based on their types into different tables in the order as listed below. [read more about ODDS]

Multi-dimensional point datasets: There is one record per data point, and each record contains several attributes.
Time series graph datasets for event detection: Temporal graph data where the graph changes dynamically over time in which new nodes and edges arrive or existing nodes and edges disappear.
Time series point datasets (Multivariate/Univariate): Temporal point data where each point has one or more attributes and the attributes change over time.
Adversarial/Attack scenario and security datasets: Opinion fraud detection data from online review system. Cyber security data, e.g. intrusion detection with DoS, DDoS etc. attack scenario. 
Crowded scene video data for anomaly detection: Video clips acquired with camera.
