ActPerFL: Active Personalized Federated Learning

no code implementations FL4NLP (ACL) 2022 Huili Chen, Jie Ding, Eric Tramel, Shuang Wu, Anit Kumar Sahu, Salman Avestimehr, Tao Zhang

Inspired by Bayesian hierarchical models, we develop ActPerFL, a self-aware personalized FL method where each client can automatically balance the training of its local personal model and the global model that implicitly contributes to other clients’ training.

ProFlip: Targeted Trojan Attack With Progressive Bit Flips

no code implementations ICCV 2021 Huili Chen, Cheng Fu, Jishen Zhao, Farinaz Koushanfar

In this work, we present ProFlip, the first targeted Trojan attack framework that can divert the prediction of the DNN to the target class by progressively identifying and flipping a small set of bits in model parameters.

Dyadic Speech-based Affect Recognition using DAMI-P2C Parent-child Multimodal Interaction Dataset

no code implementations20 Aug 2020 Huili Chen, Yue Zhang, Felix Weninger, Rosalind Picard, Cynthia Breazeal, Hae Won Park

Automatic speech-based affect recognition of individuals in dyadic conversation is a challenging task, in part because of its heavy reliance on manual pre-processing.

BlackMarks: Black-box Multi-bit Watermarking for Deep Neural Networks

no code implementations ICLR 2019 Huili Chen, Bita Darvish Rouhani, Farinaz Koushanfar

To extract the WM, BlackMarks queries the model with the WM key images and decodes the owner’s signature from the corresponding predictions using the designed encoding scheme.

DeepSigns: A Generic Watermarking Framework for IP Protection of Deep Learning Models

2 code implementations2 Apr 2018 Bita Darvish Rouhani, Huili Chen, Farinaz Koushanfar

The resulting models are therefore considered to be the IP of the model builder and need to be protected to preserve the owner's competitive advantage.
