Optimizing Quantum Federated Learning Based on Federated Quantum Natural Gradient Descent

ICASSP 2023accepted

Quantum federated learning (QFL) is a quantum extension of the classical federated learning model across multiple local quantum devices. An efficient optimization algorithm is always expected to minimize the communication overhead among different quantum participants. In this work, we propose an eff…

Classical-To-Quantum Transfer Learning for Spoken Command Recognition Based on Quantum Neural Networks

ICASSP 2022accepted

This work investigates an extension of transfer learning applied in machine learning algorithms to the emerging hybrid end-to-end quantum neural network (QNN) for spoken command recognition (SCR). Our QNN-based SCR system is composed of classical and quantum components: (1) the classical part mainly…

Submodular Rank Aggregation on Score-Based Permutations for Distributed Automatic Speech Recognition

ICASSP 2020accepted

Distributed automatic speech recognition (ASR) requires to aggregate outputs of distributed deep neural network (DNN)-based models. This work studies the use of submodular functions to design a rank aggregation on score-based permutations, which can be used for distributed ASR systems in both superv…

Distributed Submodular Maximization for Large Vocabulary Continuous Speech Recognition

ICASSP 2018accepted

Huge training datasets for automatic speech recognition (ASR) typically contain redundant information so that a subset of data is generally enough to obtain similar ASR performance to that obtained when the entire dataset is employed for training. Although the centralized submodular-based data selec…

Deep multi-view representation learning for multi-modal features of the schizophrenia and schizo-affective disorder

ICASSP 2016accepted

This work is originated from the MLSP 2014 Classification Challenge which tries to automatically detect subjects with schizophrenia and schizo-affective disorder by analyzing multi-modal features derived from magnetic resonance imaging (MRI) data. We employ Deep Neural Network (DNN)-based multi-view…
