Facebook has developed a system for its Artificial Intelligence (AI) mechanisms that teaches them to forget certain information when it is not important to perform their functions, thus saving on memory and processing costs.

The new technology, called Expire-Span, is “the first operation of its kind” according to the company, and seeks to make the neural networks of AI look like the human brain work, which constantly forget data, as reported by Facebook in a statement.

AI mechanisms tend to process information indiscriminately, but when this amount of data is very high, as in the case of long texts or videos, computing costs can become unsustainable.

The technology created by Facebook works first by predicting which information is most relevant to the functioning of a neural network and, based on this information, associates the data with an expiration date after which it is erased.

In this way, information essential to its operation is retained for longer, while irrelevant information is quickly removed, freeing up system memory space to focus on core tasks.
