Benefits of technology

This invention provides an algorithm that uses computerized techniques for evaluating properties like construction quality or energy efficiency from different types of houses found within one area. It does this through analyzing these attributes with respect to their impacts on various aspects such as cost savings, durability, safety concerns, etc., which can help improve overall performance and reduce costs associated therewith.

Problems solved by technology

The technical problem addressed by this patented technology relates to evaluating building value accurately through simulation-based methods that involve combining different types of data from multiple sources like physical properties or economic factors together. These techniques can result in incorrect interpretation due to correlated structural relationships among certain aspects of each type of data source being analyzed. This impacts how well an estimator calculates prices for specific structures within those particular scenarios.

Abstract

The invention discloses a building value evaluation based calculation method and device. The method comprises obtaining configuration data of a plurality of buildings; building a function distribution model of a plurality of buildings through a machine learning method to obtain function characteristic distribution of the plurality of the buildings; calculating similarities between the value determined buildings and buildings to be evaluated according to the function characteristic distribution; determining at least one value determined building which is largest in similarity to the buildings to be evaluated to form a similar building set; determining values of the buildings to be evaluated based on values of all the buildings in the similar building set. By means of the method and the device, different configuration property characteristics of the buildings can be used effectively, and high accuracy and good explainability can be obtained during value evaluation of the buildings.
