Nonlinear Causal Discovery via Kernel Anchor Regression

1 code implementation30 Oct 2022 Wenqi Shi, Wenkai Xu

Anchor regression has been developed to address this problem for a large class of causal graphical models, though the relationships between the variables are assumed to be linear.

Multi-user Co-inference with Batch Processing Capable Edge Server

no code implementations3 Jun 2022 Wenqi Shi, Sheng Zhou, Zhisheng Niu, Miao Jiang, Lu Geng

To deal with the coupled offloading and scheduling introduced by concurrent batch processing, we first consider an offline problem with a constant edge inference latency and the same latency constraint.

Joint Device Scheduling and Resource Allocation for Latency Constrained Wireless Federated Learning

no code implementations14 Jul 2020 Wenqi Shi, Sheng Zhou, Zhisheng Niu, Miao Jiang, Lu Geng

Then, a greedy device scheduling algorithm is introduced, which in each step selects the device consuming the least updating time obtained by the optimal bandwidth allocation, until the lower bound begins to increase, meaning that scheduling more devices will degrade the model accuracy.

Device Scheduling with Fast Convergence for Wireless Federated Learning

no code implementations3 Nov 2019 Wenqi Shi, Sheng Zhou, Zhisheng Niu

In each iteration of FL (called round), the edge devices update local models based on their own data and contribute to the global training by uploading the model updates via wireless channels.

Improving Device-Edge Cooperative Inference of Deep Learning via 2-Step Pruning

1 code implementation8 Mar 2019 Wenqi Shi, Yunzhong Hou, Sheng Zhou, Zhisheng Niu, Yang Zhang, Lu Geng

Since the output data size of a DNN layer can be larger than that of the raw data, offloading intermediate data between layers can suffer from high transmission latency under limited wireless bandwidth.
