#samasource

Brenda loads up an image, and then uses the mouse to trace around just about everything. People, cars, road signs, lane markings - even the sky, specifying whether it's cloudy or bright. Ingesting millions of these images into an artificial intelligence system means a self-driving car, to use one example, can begin to "recognise" those objects in the real world. The more data, the supposedly smarter the machine.

Brenda does this work for Samasource, a San Francisco-based company that counts Google, Microsoft, Salesforce and Yahoo among its clients. Most of these firms don't like to discuss the exact nature of their work with Samasource - as it is often for future projects - but it can be said that the information prepared here forms a crucial part of some of Silicon Valley's biggest and most famous efforts in AI.
