Incorporating Domain Differential Equations into Graph Convolutional Networks to Lower Generalization Discrepancy

no code implementations1 Apr 2024 Yue Sun, Chao Chen, Yuesheng Xu, Sihong Xie, Rick S. Blum, Parv Venkitasubramaniam

We theoretically derive conditions where GCNs incorporating such domain differential equations are robust to mismatched training and testing data compared to baseline domain agnostic models.

RQP-SGD: Differential Private Machine Learning through Noisy SGD and Randomized Quantization

no code implementations9 Feb 2024 Ce Feng, Parv Venkitasubramaniam

In this context, implementing machine learning (ML) models with real-valued weight parameters can prove to be impractical particularly for large models, and there is a need to train models with quantized discrete weights.

Spectral-DP: Differentially Private Deep Learning through Spectral Perturbation and Filtering

no code implementations25 Jul 2023 Ce Feng, Nuo Xu, Wujie Wen, Parv Venkitasubramaniam, Caiwen Ding

In particular, for fully connected layers, we combine a block-circulant based spatial restructuring with Spectral-DP to achieve better utility.

NeuGuard: Lightweight Neuron-Guided Defense against Membership Inference Attacks

1 code implementation11 Jun 2022 Nuo Xu, Binghui Wang, Ran Ran, Wujie Wen, Parv Venkitasubramaniam

Membership inference attacks (MIAs) against machine learning models can lead to serious privacy risks for the training dataset used in the model training.

Data-Driven Contract Design for Multi-Agent Systems with Collusion Detection

no code implementations6 May 2021 Nayara Aguiar, Parv Venkitasubramaniam, Vijay Gupta

For a duopoly in which agents are coupled in their payments, we show that if the principal and the agents interact finitely many times, the agents can derive rent by colluding even if the principal knows the types of the agents.

Modeling and Detection of Future Cyber-Enabled DSM Data Attacks using Supervised Learning

no code implementations27 Sep 2019 Kostas Hatalis, Parv Venkitasubramaniam, Shalinee Kishore

In future smart grids, certain portions of a customers load usage could be under automatic control with a cyber-enabled DSM program which selectively schedules loads as a function of electricity prices to improve power balance and grid stability.
