Deep Learning based Covert Attack Identification for Industrial Control Systems

no code implementations25 Sep 2020 Dan Li, Paritosh Ramanan, Nagi Gebraeel, Kamran Paynabar

This data-driven framework considers the temporal behavior of a generic physical system that extracts features from the time series of the sensor measurements that can be used for detecting covert attacks, distinguishing them from equipment faults, as well as localize the attack/fault.

AKM$^2$D : An Adaptive Framework for Online Sensing and Anomaly Quantification

no code implementations4 Oct 2019 Hao Yan, Kamran Paynabar, Jianjun Shi

In point-based sensing systems such as coordinate measuring machines (CMM) and laser ultrasonics where complete sensing is impractical due to the high sensing time and cost, adaptive sensing through a systematic exploration is vital for online inspection and anomaly quantification.

Large Multistream Data Analytics for Monitoring and Diagnostics in Manufacturing Systems

no code implementations26 Dec 2018 Samaneh Ebrahimi, Chitta Ranjan, Kamran Paynabar

The high-dimensionality and volume of large scale multistream data has inhibited significant research progress in developing an integrated monitoring and diagnostics (M&D) approach.

Structured Point Cloud Data Analysis via Regularized Tensor Regression for Process Modeling and Optimization

no code implementations26 Jul 2018 Hao Yan, Kamran Paynabar, Massimo Pacella

Advanced 3D metrology technologies such as Coordinate Measuring Machine (CMM) and laser 3D scanners have facilitated the collection of massive point cloud data, beneficial for process monitoring, control and optimization.

Sequence Graph Transform (SGT): A Feature Extraction Function for Sequence Data Mining (Extended Version)

1 code implementation11 Aug 2016 Chitta Ranjan, Samaneh Ebrahimi, Kamran Paynabar

However, sequence mining is particularly challenging because of difficulty in finding (dis)similarity/distance between sequences.

The Impact of Estimation: A New Method for Clustering and Trajectory Estimation in Patient Flow Modeling

no code implementations28 May 2015 Chitta Ranjan, Kamran Paynabar, Jonathan E. Helm, Julian Pan

CSI functions by clustering patients into groups based on similarity of trajectory using a novel Semi-Markov model (SMM)-based clustering scheme proposed in this paper, as opposed to clustering by admit type or condition as in previous literature.
