Differentially Private and Adversarially Robust Machine Learning: An Empirical Evaluation

no code implementations18 Jan 2024 Janvi Thakkar, Giulio Zizzo, Sergio Maffeis

Malicious adversaries can attack machine learning models to infer sensitive information or damage the system by launching a series of evasion attacks.

Elevating Defenses: Bridging Adversarial Training and Watermarking for Model Resilience

no code implementations21 Dec 2023 Janvi Thakkar, Giulio Zizzo, Sergio Maffeis

We use adversarial training together with adversarial watermarks to train a robust watermarked model.

FedSpectral+: Spectral Clustering using Federated Learning

no code implementations4 Feb 2023 Janvi Thakkar, Devvrat Joshi

While the distributed spectral clustering algorithm exists, they face the problem of data privacy and increased communication costs between the clients.

k-Means SubClustering: A Differentially Private Algorithm with Improved Clustering Quality

no code implementations7 Jan 2023 Devvrat Joshi, Janvi Thakkar

These DP mechanisms do not guarantee convergence of differentially private iterative algorithms and degrade the quality of the cluster.

Merged-GHCIDR: Geometrical Approach to Reduce Image Data

no code implementations6 Sep 2022 Devvrat Joshi, Janvi Thakkar, Siddharth Soni, Shril Mody, Rohan Patil, Nipun Batra

We propose two variations: Geometrical Homogeneous Clustering for Image Data Reduction (GHCIDR) and Merged-GHCIDR upon the baseline algorithm - Reduction through Homogeneous Clustering (RHC) to achieve better accuracy and training time.

Geometrical Homogeneous Clustering for Image Data Reduction

1 code implementation27 Aug 2022 Shril Mody, Janvi Thakkar, Devvrat Joshi, Siddharth Soni, Rohan Patil, Nipun Batra

The intuition behind the first approach, RHCKON, is that the boundary points contribute significantly towards the representation of clusters.
