Nvidia is telling the world before its GPU Technology conference in San Jose on May 8-May 11.

Writing in his bog, Nvidia’s vice president of business development Jeff Herbst said Nvidia will provide technical guidance, joint marketing help, strategic direction, and other aid. Nvidia made the investments through its GPU Ventures program.

The start-ups include Abeja, a Tokyo-based startup focused on AI-powered retail analytics systems; Datalogue, a New York AI data-mining platform; Optimus Ride an MIT spinoff looking at autonomous vehicles; SoundHound, which makes voice-enabled AI solutions; TempoQuest — Bouldera, which is creating GPU-accelerated weather forecasting and Zebra Medical an Israeli-based start-up using AI to read medical images.

Nvidia also made its third investment in MapD, which uses GPUs to query massive databases and is about to announce another AI startup investment.
