Building Data set

The current dataset is prepared to feed ML algorithms for finding emergency exits in buildings. Emergency exits are the two doors on each floor that connect an air-lock space to the stairwell, and the pattern is quite similar in most high-rise buildings. This led to the selection of the following two attributes: 'the distance to the nearest door' and 'the distance to the nearest stairwell'. The datasets comprise manually labeled data with 1732 door samples from four high-rise building models, containing 1517 'non-Emergency Exit' and 215 'Emergency Exit', each with the two mentioned attributes.本数据集旨在为机器学习（Machine Learning）算法提供训练数据，以实现建筑物内紧急出口的识别任务。紧急出口指每层楼中连接气闸空间与楼梯间的两道门，该布局形式在绝大多数高层建筑中高度一致。基于此，本次研究选取了如下两个特征属性：“距最近门的距离”与“距最近楼梯间的距离”。 本数据集包含经人工标注的样本数据，源自4栋高层建筑模型，共计1732个门样本，其中1517个为“非紧急出口”样本，215个为“紧急出口”样本，所有样本均标注了上述提及的两个特征属性。
