TAMIS: Tailored Membership Inference Attacks on Synthetic Data
In this paper, we propose TAMIS, a novel MIA against differentially-private synthetic data generation methods that rely on graphical models.
Analysis of Speech Temporal Dynamics in the Context of Speaker Verification and Voice Anonymization
In this paper, we investigate the impact of speech temporal dynamics in application to automatic speaker verification and speaker voice anonymization tasks.
TAROT: Task-Oriented Authorship Obfuscation Using Policy Optimization Methods
Our approach leverages policy optimization as a fine-tuning paradigm over small language models in order to rewrite texts by preserving author identity and downstream task utility.
Rényi Pufferfish Privacy: General Additive Noise Mechanisms and Privacy Amplification by Iteration
Pufferfish privacy is a flexible generalization of differential privacy that allows to model arbitrary secrets and adversary's prior knowledge about the data.
Improved Stability and Generalization Guarantees of the Decentralized SGD Algorithm
On the contrary, we show, for convex, strongly convex and non-convex functions, that D-SGD can always recover generalization bounds analogous to those of classical SGD, suggesting that the choice of graph does not matter.
Differential Privacy has Bounded Impact on Fairness in Classification
We theoretically study the impact of differential privacy on fairness in classification.
FLamby: Datasets and Benchmarks for Cross-Silo Federated Learning in Realistic Healthcare Settings
In this work, we propose a novel cross-silo dataset suite focused on healthcare, FLamby (Federated Learning AMple Benchmark of Your cross-silo strategies), to bridge the gap between theory and practice of cross-silo FL.
Collaborative Algorithms for Online Personalized Mean Estimation
We study the case where some of the distributions have the same mean, and the agents are allowed to actively query information from other agents.

In this paper, we study differentially private empirical risk minimization (DP-ERM).
Refined Convergence and Topology Learning for Decentralized SGD with Heterogeneous Data
One of the key challenges in decentralized and federated learning is to design algorithms that efficiently deal with highly heterogeneous data distributions across agents.
Differentially Private Speaker Anonymization
We remove speaker information from these attributes by introducing differentially private feature extractors based on an autoencoder and an automatic speech recognizer, respectively, trained using noise layers.

Fully Decentralized Joint Learning of Personalized Models and Collaboration Graphs
We consider the fully decentralized machine learning scenario where many users with personal datasets collaborate to learn models through local peer-to-peer exchanges, without a central coordinator.
Personalized and Private Peer-to-Peer Machine Learning
The rise of connected personal devices together with privacy concerns call for machine learning algorithms capable of leveraging the data of a large number of agents to learn personalized models under strong privacy requirements.
