GPT-FL: Generative Pre-trained Model-Assisted Federated Learning

1 code implementation3 Jun 2023 Tuo Zhang, Tiantian Feng, Samiul Alam, Dimitrios Dimitriadis, Mi Zhang, Shrikanth S. Narayanan, Salman Avestimehr

Through comprehensive ablation analysis, we discover that the downstream model generated by synthetic data plays a crucial role in controlling the direction of gradient diversity during FL training, which enhances convergence speed and contributes to the notable accuracy boost observed with GPT-FL.

Attribute Inference Attack of Speech Emotion Recognition in Federated Learning Settings

1 code implementation26 Dec 2021 Tiantian Feng, Hanieh Hashemi, Rajat Hebbar, Murali Annavaram, Shrikanth S. Narayanan

To assess the information leakage of SER systems trained using FL, we propose an attribute inference attack framework that infers sensitive attribute information of the clients from shared gradients or model parameters, corresponding to the FedSGD and the FedAvg training algorithms, respectively.

Attention-gated convolutional neural networks for off-resonance correction of spiral real-time MRI

no code implementations14 Feb 2021 Yongwan Lim, Shrikanth S. Narayanan, Krishna S. Nayak

Spiral acquisitions are preferred in real-time MRI because of their efficiency, which has made it possible to capture vocal tract dynamics during natural speech.
