The overfitted brain: Dreams evolved to assist generalization

Dreaming about flying might help you balance yourself better while running. A new study hypothesizes that dreams are created to introduce corrupted or stochastic data into our brains to sharpen our generalization skills and to prevent overfitting. Overfitting is the overspecialization of a neural network (biological or artificial) towards one dataset, and it makes it more difficult for neural networks to handle different data sets, making them perform worse at other tasks.
