The number of apparel industry roles in North America made up 81.1 per cent of total machine learning jobs – up from 72.3 per cent in the same quarter in 2020.

That was followed by Asia-Pacific, which saw a 1.7 year-on-year percentage point change in machine learning roles.

The figures are compiled by Just Style's parent company 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.
