投影寻踪法在高层建筑火灾风险评估中的应用
Application of Projection Pursuit Method to Evaluation of Fire Risk of High-rise Building
摘要
Abstract
In order to solve we problem of subjectivity and low distinguish ability in the published literatures on evaluation method of the high-rise building fire risk evaluation,we propose a new model———Fire risk evaluation of the high-rise building based on projection pursuit clustering (PPC).The multi-dimensional data can be synthe-sized with one-dimensional space in this model;the model was optimized by Particle Swarm Optimization,and then calculated projection values of the measured samples according to the optimal projection direction.Finally,analysis fire risk by comparing the level projection output value to the projection values of the measured samples,and com-parative its evaluation results with other typical methods.Studies shows that this model is more reasonable and reli-able than several other methods,not only overcome the limitations of weight values influenced by human,but also had higher resolution and classification accuracy.It had good applicability,provides a more application and popu-larization new method for the high-rise building fire risk evaluation.关键词
