The goal is to ensure quality for a period of time after you buy it. That can be several days to several weeks, depending on the item. For instance, milk, assuming proper refrigeration, should last five to seven days past its sell-by date before turning sour.
An autoencoder is a neural network that is trained in an unsupervised fashion. The goal of an autoencoder is to find a more compact representation of the data by learning an encoder, which transforms the data to their corresponding compact representation, and a decoder, which reconstructs the original data.
Encoders. From Battlebots to the Mars Rover, large construction vehicles to semiconductor manufacturing equipment, wherever there is motion, an encoder is sure to be found. Encoders may not be as glamorous as the products they go in, but they are critical in today's complex and sophisticated motion control systems.
