Robust Projection based Anomaly Extraction (RPE) in Univariate Time-Series
Mostafa Rahmani, Anoop Deoras, Laurent Callot
This paper presents a novel, closed-form, and data/computation efficient online anomaly detection algorithm for time-series data. The proposed method, dubbed RPE, is a window-based…
Non-Local Feature Aggregation on Graphs via Latent Fixed Data Structures
Mostafa Rahmani, Rasoul Shafipour, Ping Li
In contrast to image/text data whose order can be used to perform non-local feature aggregation in a straightforward way using the pooling layers, graphs lack the tensor representa…
Closed-Form, Provable, and Robust PCA via Leverage Statistics and Innovation Search
Mostafa Rahmani, Ping Li
The idea of Innovation Search, which was initially proposed for data clustering, was recently used for outlier detection. In the application of Innovation Search for outlier detect…
Outlier Detection and Data Clustering via Innovation Search
Mostafa Rahmani, Ping Li
The idea of Innovation Search was proposed as a data clustering method in which the directions of innovation were utilized to compute the adjacency matrix and it was shown that Inn…
