The Ottendorf Viaduct on the Riesa-Chemnitz railway line stood for over 160 years until it could no longer be saved and had to be replaced in 2015. The new replacement structure built at that time was a first for Deutsche Bahn: For the first time in its history, it built a bridge with a frame-stiffened arch structure. Although 3D models were used to some extent in the planning of the structure, the BIM method was not applied, so that no digital twin of the bridge is available for future (maintenance) work.

AI in Real-World Robotics

Article | July 19, 2021

While experts debate the finer points of what constitutes a true general artificial intelligence (AI) and the various steps that can get us there, it isn’t in any doubt that robots are getting smarter –and learning how to make better decisions-- thanks to various AI-related systems. From the autonomous cars on our roads and the autonomous mobile robots in the world’s warehouses through to AI-powered machine vision systems, edge computing in manufacturing environments, and agricultural drones that can process huge amounts of data on the fly, AI greatly enhances robot performance by providing bots with intelligent decision-making capabilities based on an analysis of billions of data points coupled with neural network and deep learning strategies. Crucially, AI enables robots to be more flexible, while at the same time enhancing traceability across all types of automation processes.

Feature engineering in machine learning

Article | April 24, 2020

Feature engineering is the process of extracting new variables by transforming raw data to improve the predictability of a machine learning model. But feature engineering is not just this kind of simple translation of categories like names or colors into numbers. The following section includes a collection of different kinds of engineering approaches that go beyond a translation of categories into numbers and address needs such as transforming numbers into categories or filtering data points due to missing or false data.
