AI & Robotics

Transfer learning, or a technique that entails pretraining an AI model on a data-rich task before fine-tuning it on another task, has been successfully applied in domains from robotics to object classification. But it holds particular promise in the subfield of natural language processing (NLP), where it’s given rise to a diversity of benchmark-besting approaches. To advance it further…

The process relied on a convolutional neural network that pored over 4,396 CT scans. That’s a comparatively small number of samples, but the abnormalities were detailed “at the pixel level,” according to UCSF. In other words, they were far less likely to misinterpret noise and other errors as hemorrhages. The technique also had the AI training on part of an image at a time rather…

Viz.ai, a healthcare startup that’s using artificial intelligence (AI) to help medical professionals spot the early signs of stroke, has raised $50 million in a series B round of funding led by Greenoaks, with participation from Alphabet’s VC arm GV and Kleiner Perkins. In the U.S. alone, someone has a stroke every 40 seconds, according to data from the Centers for Disease Control and…

France’s aggressive push to develop its AI ecosystem seems to be paying dividends as the number of startups continues to soar. A new report released today identified 432 AI-related startups in France, up from 312 last year and 180 back in 2016. The report was produced by Roland Berger, a global consulting firm, and France Digitale, an association that represents venture capitalist and…
