In the evolving landscape of Building Information Modeling (BIM), recognized as a leading technology in construction, the development of three-dimensional BIM objects forms the cornerstone of digitally representing and purposefully utilizing information on building elements. Most BIM capabilities and applications throughout the lifecycle of construction industry projects rely on the geometric and non-geometric information embedded in these developed objects. However, the arbitrary assignment of properties within objects can hinder the efficiency of BIM applications during project lifecycles. The BIM object library is an effective resource for storing and supplying essential objects across... 

Nowadays, methods based on deep learning networks are the most effective artificial in­ telligence methods. Although they have achieved success in various fields (such as machine vision and object recognition), practical and experimental cases show the fragility of deep learning networks against perturbations and unwanted changes of the input pattern. All these perturbations must be in a way that the main class of the perturbed input pattern can be rec­ ognized by human, but the network makes a mistake in recognizing its correct class. This thesis seeks a more accurate evaluation by designing adversarial attacks such that the main class of the adversarial pattern is detectable by human...
