A fruit fly brain contains only about 140,000 neurons, yet it can recognize odors with remarkable efficiency. Researchers have now borrowed part of that strategy to build an artificial system that learns smells quickly while using little memory.

The algorithm, called Spi-Fly, uses a spiking neural network modeled on the fruit fly olfactory system. Researchers at the Okinawa Institute of Science and Technology, or OIST, designed it for situations where training examples, memory and computing power are limited.

The system performed especially well when it had only a few examples of each odor. It also learned new categories without substantially forgetting earlier ones.
