Asia-Pacific was the fastest growing region for machine learning hiring among railway industry companies in the three months ending October.
The number of roles in Asia-Pacific made up 16.9 per cent of total machine learning jobs – up from 14.4 per cent in the same quarter last year.
That was followed by Europe, which saw a 1.4 year-on-year percentage point change in machine learning roles.
The figures are compiled by GlobalData, who track the number of new job postings from key companies in various sectors over time. Using textual analysis, these job advertisements are then classified thematically.
GlobalData's thematic approach to sector activity seeks to group key company information by topic to see which companies are best placed to weather the disruptions coming to their industries.
These key themes, which include machine learning, are chosen to cover "any issue that keeps a CEO awake at night".
By tracking them across job advertisements it allows us to see which companies are leading the way on specific issues and which are dragging their heels - and importantly where the market is expanding and contracting.
