Expire-Span: The New AI Algorithm that Forgets Irrelevant Information

On May 14, the AI Facebook Research Team has published an article regarding Expire-Span, a human-brain like algorithm which learns to forget the irrelevant information. Expire-Span, a method that learns to retain the most important information and expire the irrelevant information. In practice, Expire-Span is a deep learning algorithm, which first predicts the most relevant information for a given task, and then it equips every information with an expiration date, namely a deadline. When the date expires, the associated information is forgotten. This aspect permits the Expire-Span algorithm to be very scalable in terms of memory.
