Accelerated Distributed Aggregative Optimization

no code implementations17 Apr 2023 Jiaxu Liu, Song Chen, Shengze Cai, Chao Xu

In this paper, we investigate a distributed aggregative optimization problem in a network, where each agent has its own local cost function which depends not only on the local state variable but also on an aggregated function of state variables from all agents.

Language-aware Multiple Datasets Detection Pretraining for DETRs

no code implementations7 Apr 2023 Jing Hao, Song Chen, Xiaodi Wang, Shumin Han

Pretraining on large-scale datasets can boost the performance of object detectors while the annotated datasets for object detection are hard to scale up due to the high labor cost.

The Novel Adaptive Fractional Order Gradient Decent Algorithms Design via Robust Control

no code implementations8 Mar 2023 Jiaxu Liu, Song Chen, Shengze Cai, Chao Xu

The vanilla fractional order gradient descent may oscillatively converge to a region around the global minimum instead of converging to the exact minimum point, or even diverge, in the case where the objective function is strongly convex.

Task modules Partitioning, Scheduling and Floorplanning for Partially Dynamically Reconfigurable Systems Based on Modern Heterogeneous FPGAs

no code implementations11 Dec 2022 Bo Ding, Jinglei Huang, Junpeng Wang, Qi Xu, Song Chen, Yi Kang

To better solve the problems in the automation process of FPGA-PDRS and narrow the gap between algorithm and application, in this paper, we propose a complete workflow including three parts, pre-processing to generate the list of task modules candidate shapes according to the resources requirements, exploration process to search the solution of task modules partitioning, scheduling, and floorplanning, and post-optimization to improve the success rate of floorplan.

Sentiment Word Aware Multimodal Refinement for Multimodal Sentiment Analysis with ASR Errors

1 code implementation Findings (ACL) 2022 Yang Wu, Yanyan Zhao, Hao Yang, Song Chen, Bing Qin, Xiaohuan Cao, Wenting Zhao

Through further analysis of the ASR outputs, we find that in some cases the sentiment words, the key sentiment elements in the textual modality, are recognized as other words, which makes the sentiment of the text change and hurts the performance of multimodal sentiment models directly.
