Robust Multimodal Fusion for Human Activity Recognition

no code implementations8 Mar 2023 Sanju Xaviar, Xin Yang, Omid Ardakanian

Compared to 2 related robust fusion architectures, Centaur is more robust, achieving 11. 59-17. 52% higher accuracy in HAR, especially in the presence of consecutive missing data in multiple sensor channels.

Blinder: End-to-end Privacy Protection in Sensing Systems via Personalized Federated Learning

1 code implementation24 Sep 2022 Xin Yang, Omid Ardakanian

This paper proposes a sensor data anonymization model that is trained on decentralized data and strikes a desirable trade-off between data utility and privacy, even in heterogeneous settings where the sensor data have different underlying distributions.

False Data Injection Attack on Electric Vehicle-Assisted Voltage Regulation

no code implementations9 Mar 2022 YuAn Liu, Omid Ardakanian, Ioanis Nikolaidis, Hao Liang

With the large scale penetration of electric vehicles (EVs) and the advent of bidirectional chargers, EV aggregators will become a major player in the voltage regulation market.

A Data-Efficient Approach to Behind-the-Meter Solar Generation Disaggregation

no code implementations17 May 2021 Xinlei Chen, Moosa Moghimi Haji, Omid Ardakanian

With the emergence of cost effective battery storage and the decline in the solar photovoltaic (PV) levelized cost of energy (LCOE), the number of behind-the-meter solar PV systems is expected to increase steadily.

Non-Intrusive Load Monitoring

Anonymizing Sensor Data on the Edge: A Representation Learning and Transformation Approach

no code implementations16 Nov 2020 Omid Hajihassani, Omid Ardakanian, Hamzeh Khazaei

In the deterministic case, we use a linear transformation to move the representation of input data in the latent space such that the reconstructed data is likely to have the same public attribute but a different private attribute than the original input data.

On Identification of Distribution Grids

1 code implementation5 Nov 2017 Omid Ardakanian, Vincent W. S. Wong, Roel Dobbe, Steven H. Low, Alexandra von Meier, Claire Tomlin, Ye Yuan

Large-scale integration of distributed energy resources into residential distribution feeders necessitates careful control of their operation through power flow analysis.

Inverse Power Flow Problem

no code implementations21 Oct 2016 Ye Yuan, Steven Low, Omid Ardakanian, Claire Tomlin

We show that the admittance matrix can be uniquely identified from a sequence of measurements corresponding to different steady states when every node in the system is equipped with a measurement device, and a Kron-reduced admittance matrix can be determined even if some nodes in the system are not monitored (hidden nodes).
