(English Abstract)
In this work, we propose a method of learning the weights of weighted Euclidean distance function using perceptron learning for fire prediction. In our work, the data used to fire prediction include building data, regional administration data and energy consumption data. When locating fire buildings with distance functions, it is not appropriate to adopt Euclidean distance function with no weights; this is because fire data has various types of features and large difference in scales of feature values. Thus our fire prediction method measures distances between two buildings using weighted Euclidean distance function. The weights of weighted Euclidean distance function can be given according to the feature importance, not depending upon user input. Our experimental result shows that it is possible to locate fire-risk building by using weights obtained by the perceptron learning.
