Humans have traditionally been very good at recognizing emotions on people’s faces, but computers?

Microsoft researchers are at the forefront of efforts to help people without a machine learning background teach their systems to get better based on experience.

They’re calling this new evolution machine teaching.

“No one has really built a machine learning tool for the layman,” said Patrice Simard, a distinguished engineer with Microsoft Research who is leading a new machine teaching research project at Microsoft Research.

Machine learning, in which systems get smarter as they receive more data, has proved incredibly useful for building more personal computing experiences.

Thanks to machine learning, your e-mail inbox is mostly free of spam and other unwanted e-mail, and your smart phone can constantly improve its understanding what your personal needs are based on what you say and do.
