On the fringes of the Indian city of Kolkata, in the dusty, crowded neighbourhood of Metiabruz, 460 young women are working at the vanguard of artificial intelligence.
The women, mostly from the local Muslim community, are helping to train computer vision algorithms used in autonomous vehicles and augmented reality systems, for the likes of Amazon, Microsoft, eBay and TripAdvisor.
The all-female centre is one of eight Indian offices operated by iMerit, an India- and US-based data annotation company, whose 2,200 local employees label the oceans of data generated by industries as diverse as manufacturing, medical imaging, autonomous driving, retail, insurance and agriculture.
