Item Improving Vision-Based Freight Vehicle Detection in Smart Cities Using Generative Adversarial Networks(2025-01-07) Xu, Shihan; Mccarthy, Chris; Jayaraman, Prem Prakash; Ghaderi, Hadi; Dia, HusseinA freight activity grows within urban areas, accurately estimating their impact becomes crucial for effective planning and modelling of transport infrastructure. Reliable Origin-Destination (OD) information is essential for strategic transport models, which guide future infrastructure investments and sustainable urban development. In this paper we propose a Generative Adversarial Network (GAN)-based domain adaptation approach for accurately detecting heavy vehicles from low-quality surveillance data under varying lighting conditions. To the best of our knowledge, this is the first study to use GAN-based data augmentation for freight vehicle movement analysis in smart cities, contributing to the development of more efficient, scalable, and reliable smart city planning solutions.Item Large Language Models for Marketing Research: A Survey and New Perspectives(2025-01-07) Qian, Yang; Chen, Shaoge; Wu, Chenyang; Yuan, Kun; Du, Yanan; Jiang, Yuanchun; Liu, YezhengLarge Language Models (LLMs) have brought unprecedented innovation opportunities to the marketing field. However, the practical applications of LLMs within the marketing landscape currently exhibit a fragmented and scattered nature. In this study, we aim to aggregate these scattered literature to create a holistic view of LLMs capabilities for marketing research. Specifically, we present an overview of LLMs using the evolution of LMs. Subsequently, we explore their application in the marketing domain across five distinct dimensions: data annotation, idea inspiration and content generation, substitution of human participants, user behavior learning and prediction, and evaluation of LLM feedback. Finally, we discuss the new trends and challenges for LLMs in marketing. This study enriches the theoretical foundations of integrating generative AI with marketing practices.Item Introduction to the Minitrack on Decision Support for Smart City(2025-01-07) Sun, Jianshan; Xu, Wei; Ma, Jian
