It's time for communication vendors to start investing in machine learning. Machine learning seems like the only topic in the computer science world today. In many cases, it comes with the terms "deep learning," or even better, "artificial intelligence" (AI). When searching for some VC funds that specialize in AI (yes, there are a few), I bumped into VC funds driven by decisions made and supported by AI. As part of a recent study we conducted on AI technologies used in real-time communications (RTC), we looked at hundreds of voice and video communications offers -- and discovered that these services are clearly lagging behind on the use of machine learning.
