Partial Federated Learning

no code implementations3 Mar 2024 Tiantian Feng, Anil Ramakrishna, Jimit Majmudar, Charith Peris, Jixuan Wang, Clement Chung, Richard Zemel, Morteza Ziyadi, Rahul Gupta

Federated Learning (FL) is a popular algorithm to train machine learning models on user data constrained to edge devices (for example, mobile phones) due to privacy concerns.

Coordinated Replay Sample Selection for Continual Federated Learning

no code implementations23 Oct 2023 Jack Good, Jimit Majmudar, Christophe Dupuy, Jixuan Wang, Charith Peris, Clement Chung, Richard Zemel, Rahul Gupta

Continual Federated Learning (CFL) combines Federated Learning (FL), the decentralized learning of a central model on a number of client devices that may not communicate their data, and Continual Learning (CL), the learning of a model from a continual stream of data without keeping the entire history.

End-to-end spoken language understanding using joint CTC loss and self-supervised, pretrained acoustic encoders

no code implementations4 May 2023 Jixuan Wang, Martin Radfar, Kai Wei, Clement Chung

It is challenging to extract semantic meanings directly from audio signals in spoken language understanding (SLU), due to the lack of textual information.

How to Minimize the Weighted Sum AoI in Multi-Source Status Update Systems: OMA or NOMA?

no code implementations6 May 2022 Jixuan Wang, Deli Qiao

In this paper, the minimization of the weighted sum average age of information (AoI) in a multi-source status update communication system is studied.

On the data requirements of probing

1 code implementation Findings (ACL) 2022 Zining Zhu, Jixuan Wang, Bai Li, Frank Rudzicz

As large and powerful neural language models are developed, researchers have been increasingly interested in developing diagnostic tools to probe them.

Speaker attribution with voice profiles by graph-based semi-supervised learning

no code implementations6 Feb 2021 Jixuan Wang, Xiong Xiao, Jian Wu, Ranjani Ramamurthy, Frank Rudzicz, Michael Brudno

Speaker attribution is required in many real-world applications, such as meeting transcription, where speaker identity is assigned to each utterance according to speaker voice profiles.

Encoding Syntactic Knowledge in Transformer Encoder for Intent Detection and Slot Filling

no code implementations21 Dec 2020 Jixuan Wang, Kai Wei, Martin Radfar, Weiwei Zhang, Clement Chung

We propose a novel Transformer encoder-based architecture with syntactical knowledge encoded for intent detection and slot filling.

Speaker diarization with session-level speaker embedding refinement using graph neural networks

no code implementations22 May 2020 Jixuan Wang, Xiong Xiao, Jian Wu, Ranjani Ramamurthy, Frank Rudzicz, Michael Brudno

Deep speaker embedding models have been commonly used as a building block for speaker diarization systems; however, the speaker embedding model is usually trained according to a global loss defined on the training data, which could be sub-optimal for distinguishing speakers locally in a specific meeting session.

Training without training data: Improving the generalizability of automated medical abbreviation disambiguation

no code implementations12 Dec 2019 Marta Skreta, Aryan Arbabi, Jixuan Wang, Michael Brudno

Abbreviation disambiguation is important for automated clinical note processing due to the frequent use of abbreviations in clinical settings.

Centroid-based deep metric learning for speaker recognition

no code implementations6 Feb 2019 Jixuan Wang, Kuan-Chieh Wang, Marc Law, Frank Rudzicz, Michael Brudno

Speaker embedding models that utilize neural networks to map utterances to a space where distances reflect similarity between speakers have driven recent progress in the speaker recognition task.
