E-Commerce Demo Platform

Electronic commerce is an intriguing application field for algorithmic techniques originating from artificial intelligence research, machine learning and optimization due to the great demands on efficiency, usability and ease of integration with existing software systems and infrastructure. Our research team at the Lucerne University of Applied Sciences and Arts - The Lucerne School of Information Technology tackles these challenges by providing efficent, scalable and specificially tailored solutions to our partners for online and offline recommendation systems, preference-based search, user profiling and data analysis in general. These pages aim to make some of our research on the algorithmic machinery visible to a broader audience by providing a testbed of online demonstrators. Please check them out and feel free to get in touch with us!
