Spider: The Statistical Approach to Value Assignment Problem

Abstract

In the era of “Big Data,” with the advent of the artificial intelligence algorithms, a different type of real estate valuation has found its own market niche: the AVM (automated valuation method), evolution of the simplest statistical evaluation. The Spider-based approach starts from the consideration that the value of a property is certainly influenced by innumerable variables, possibly coming from different databases, but these variables can be grouped into homogeneous categories, which we will call vectors.
