How Numenta Builds Neural Networks Inspired by Sparsity in the Human Brain
Our brains only use about 30-40 watts of power, yet are more powerful than neural networks which take extensive amounts of energy to run. So what can we learn from the brain to help us build better neural networks? Join Michael McCourt as he interviews Subutai Ahmad, VP of Research at Numenta, about his latest work.
In this episode, they discuss sparsity, bioinspiration, and how Numenta is using SigOpt to help them build better neural networks and save on training costs.
