DIFFERENTIALLY PRIVATE CLUSTERED FEDERATED LEARNING WITH PRIVACY-PRESERVING INITIALIZATION AND NORMALITY-DRIVEN AGGREGATION

ICASSP 2026oral

Federated learning (FL) enables training of a global model while keeping raw data on end-devices. Despite this, FL has shown to leak private user information and thus in practice, it is often coupled with methods such as differential privacy (DP) and secure vector sum to provide formal privacy guara…

DP-LAC: LIGHTWEIGHT ADAPTIVE CLIPPING FOR DIFFERENTIALLY PRIVATE FEDERATED FINE-TUNING OF LANGUAGE MODELS

ICASSP 2026poster

Federated learning (FL) enables the collaborative training of large-scale language models (LLMs) across edge devices while keeping user data on-device. However, FL still exposes sensitive information through client-provided gradients. Differentially private stochastic gradient descent (DP-SGD) mitig…

Linear Time Complexity Conformers with SummaryMixing for Streaming Speech Recognition

ICASSP 2025accepted

Automatic speech recognition (ASR) with an encoder equipped with self-attention, whether streaming or non-streaming, takes quadratic time in the length of the speech utterance. This slows down training and decoding, increase the cost, and limits the deployment of the ASR in constrained devices. Summ…

$\texttt{pfl-research}$: simulation framework for accelerating research in Private Federated Learning

NeurIPS 2024poster

Federated learning (FL) is an emerging machine learning (ML) training paradigm where clients own their data and collaborate to train a global model, without revealing any data to the server and other participants. Researchers commonly perform experiments in a simulation environment to quickly iterat…
