Damage Assessment of Ancient Wooden Building Based on Alternative Projection Algorithm and EM Algorithm
Ancient wooden building is a valuable material and spiritual wealth. In order to evaluate the damage of the building and make rational protection, this paper established a damage assessment index system. The coefficient of each index is calculated based on the samples rather than prior assigned, which will make the evaluation more objectively. Then the interactive projection algorithm between the convex set is introduced to make least squares estimation for the regression model. The proposed model and algorithm provides a new analysis method for damage assessment of ancient wooden buildings.
