machine learning

Machine learning is a field of artificial intelligence that uses statistical techniques to give computer systems the ability to learn from data, without needing to be explicitly programmed.

It involves the science of getting computers to learn and act like humans, and to get computers to improve their learning over time in autonomous fashion, by feeding them data and information in the form of observations and real-world interactions.

Historical perspective: The name "machine learning" was coined in 1959 by Arthur Samuel. In 2018, researchers from MIT created a wearable device that can recognize nonverbal prompts, essentially reading your mind,’ said Thuy Ong in TheVerge.net. The AlterEgo, which loops around a user’s ear, follows the jawline, and attaches underneath the mouth, contains electrodes that detect neuromuscular signals in your jaw and face that are activated by internal verbalizations, or the words you’re saying in your head. Invisible to the human eye, the signals are fed into a machine-learning system that associates specific signals with words, so a user can control other devices without any movements or audible voice commands. In a video demonstrating the AlterEgo’s capabilities, a completely still user scrolls through a streaming-video menu by simply thinking directions such as “down” and “right.” In tests, the device showed 92 percent accuracy when trained on the relatively limited vocabulary of 20 words.
