Sensing spatial distribution of urban land use by integrating points-of-interest and Google Word2Vec model

TL;DR: An innovative framework that detects urban land use distributions at the scale of traffic analysis zones (TAZs) by integrating Baidu POIs and a Word2Vec model is established and can be used to help urban planners to monitor dynamic urban landUse and evaluate the impact of urban planning schemes.
Journal ArticleDOI

Using deep learning to examine street view green and blue spaces and their associations with geriatric depression in Beijing, China.

TL;DR: Findings provide support that street view green and blue spaces are protective against depression for the elderly in China, yet longitudinal confirmation to infer causality is necessary.
Journal ArticleDOI

Building Footprint Extraction from High-Resolution Images via Spatial Residual Inception Convolutional Neural Network

TL;DR: A novel fully convolutional network (FCN), in which a spatial residual inception (SRI) module is proposed to capture and aggregate multi-scale contexts for semantic understanding by successively fusing multi-level features, shows promising potential for building detection from remote sensing images on a large scale.
Journal ArticleDOI

A human-machine adversarial scoring framework for urban perception assessment using street-view images

TL;DR: A human-machine adversarial scoring framework using a methodology that incorporates deep learning and iterative feedback with recommendation scores is described, which allows for the rapid and cost-effective assessment of the local urban perceptions for Chinese cities.
Journal ArticleDOI

Urban greenery and mental wellbeing in adults: Cross-sectional mediation analyses on multiple pathways across different greenery measures.

TL;DR: Wang et al. as discussed by the authors used a population sample of 1029 adult residents of the metropolis of Guangzhou, China, from 2016 to examine how streetscape and remote sensing-based greenery affect people's mental wellbeing; whether and, if so, to what extent the associations are mediated by physical activity, stress, air quality and noise, and social cohesion.
