BIG DATA COURSE

Applications of techniques and analyzes "Big Data" for railway maintenance.

Technological advances allow for ever greater data collection. The technical challenge is how best to take advantage of the benefits and capitalize on the opportunities presented by Big Data. The application of emerging data techniques in railway maintenance, a two-day professional development course, is focused on data analysis techniques and practical case studies that are directly applicable to professionals working in Railway Engineering.
