How accurate is machine learning in speech recognition? Researchers take a look

Artificial intelligence and machine learning are all the rage--and for good reason. But researchers claim the brain doesn't actually use the regions identified by machine learning to perform a task. Rather, these algorithms reflect the mental associations related to the task. One author of the study, published online Jan. 31 in the Proceedings on the National Academy of Sciences, Anne-Lise Giraud with the department of fundamental neuroscience at the University of Geneva in Switzerland, said in a release that "learning algorithms are intelligent but ignorant. They are very sensitive and use all the information in the signals. However, they do not allow us to know whether this information was used to perform the task, or if it reflects the consequences of this task--in other words, spreading information in our brain."
