Federated Class-Incremental Learning

1 code implementation CVPR 2022 Jiahua Dong, Lixu Wang, Zhen Fang, Gan Sun, Shichao Xu, Xiao Wang, Qi Zhu

It makes the global model suffer from significant catastrophic forgetting on old classes in real-world scenarios, where local clients often collect new classes continuously and have very limited storage memory to store old classes.

Learning-based Framework for Sensor Fault-Tolerant Building HVAC Control with Model-assisted Learning

no code implementations27 Jun 2021 Shichao Xu, Yangyang Fu, YiXuan Wang, Zheng O'Neill, Qi Zhu

As people spend up to 87% of their time indoors, intelligent Heating, Ventilation, and Air Conditioning (HVAC) systems in buildings are essential for maintaining occupant comfort and reducing energy consumption.

Non-Transferable Learning: A New Approach for Model Ownership Verification and Applicability Authorization

1 code implementation ICLR 2022 Lixu Wang, Shichao Xu, Ruiqi Xu, Xiao Wang, Qi Zhu

Our NTL-based authorization approach instead provides data-centric protection, which we call applicability authorization, by significantly degrading the performance of the model on unauthorized data.

Addressing Class Imbalance in Federated Learning

2 code implementations14 Aug 2020 Lixu Wang, Shichao Xu, Xiao Wang, Qi Zhu

Our experiments demonstrate the importance of acknowledging class imbalance and taking measures as early as possible in FL training, and the effectiveness of our method in mitigating the impact.

One for Many: Transfer Learning for Building HVAC Control

no code implementations9 Aug 2020 Shichao Xu, Yi-Xuan Wang, Yanzhi Wang, Zheng O'Neill, Qi Zhu

Traditional HVAC control methods are typically based on creating explicit physical models for building thermal dynamics, which often require significant effort to develop and are difficult to achieve sufficient accuracy and efficiency for runtime building control and scalability for field implementations.

Eavesdrop the Composition Proportion of Training Labels in Federated Learning

no code implementations14 Oct 2019 Lixu Wang, Shichao Xu, Xiao Wang, Qi Zhu

Federated learning (FL) has recently emerged as a new form of collaborative machine learning, where a common model can be learned while keeping all the training data on local devices.
