Learning in Brains and Machines (3): Synergistic and Modular Action

Action synergies in the brain are paralleled by macro-actions and options in machines. In both brains and machines, these tools enable fast learning, strong generalisation and flexible action. But most importantly, for we who seek a deeper understanding of the brain, and human and machine intelligence, this has illuminated the principles of modularity an abstraction--an invaluable principle of biological and computational learning.
