Deep learning and, specifically, convoltional neural networks (CNN) represent a class of powerful models that facilitate the understanding of many problems in computer vision. When combined with a reasonable amount of data, CNNs can outperform traditional models for many tasks, including image classification. In this work, we utilize these powerful tools with imagery data collected through Google Street View images to perform virtual audits of neighborhood characteristics. We further investigate different architectures for chronic disease prevalence regression through networks that are applied to sets of images rather than single images. We show quantitative results and demonstrate that our proposed architectures outperform the traditional regression approaches.
深度学习,特别是卷积神经网络(CNN),代表了一类强大的模型,有助于理解计算机视觉中的许多问题。当与合理数量的数据相结合时,卷积神经网络在许多任务上可以超越传统模型,包括图像分类。在这项工作中,我们利用这些强大的工具和通过谷歌街景图像收集的图像数据来对邻里特征进行虚拟审计。我们进一步通过应用于图像集而非单张图像的网络,研究用于慢性病患病率回归的不同架构。我们展示了定量结果,并证明我们提出的架构优于传统的回归方法。
