Are You Being Tracked? Discover the Power of Zero-Shot Trajectory Tracing with LLMs!

no code implementations10 Mar 2024 Huanqi Yang, Sijie Ji, Rucheng Wu, Weitao Xu

There is a burgeoning discussion around the capabilities of Large Language Models (LLMs) in acting as fundamental components that can be seamlessly incorporated into Artificial Intelligence of Things (AIoT) to interpret complex trajectories.

Adaptive Top-K in SGD for Communication-Efficient Distributed Learning

no code implementations24 Oct 2022 Mengzhe Ruan, Guangfeng Yan, Yuanzhang Xiao, Linqi Song, Weitao Xu

This paper proposes a novel adaptive Top-K in SGD framework that enables an adaptive degree of sparsification for each gradient descent step to optimize the convergence performance by balancing the trade-off between communication cost and convergence error.

Occlusion-Resistant Instance Segmentation of Piglets in Farrowing Pens Using Center Clustering Network

no code implementations4 Jun 2022 Endai Huang, Axiu Mao, Junhui Hou, Yongjian Wu, Weitao Xu, Maria Camila Ceballos, Thomas D. Parsons, Kai Liu

Specifically, CClusnet-Inseg uses each pixel to predict object centers and trace these centers to form masks based on clustering results, which consists of a network for segmentation and center offset vector map, Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm, Centers-to-Mask (C2M), and Remain-Centers-to-Mask (RC2M) algorithms.
