Number of Neurons (Brain ) : 86 Billion / Number of Neurons AIs ( 150 billion / 1,744 ) = 86 Million equivalent AI Neurons Number of Synapses (Brain ) : 150 trillion / Number of parameters AIs : 150 billion = 1,000 or in other words current AIs would have to scale by a factor of one thousand their connections to be on par with the brain. So now we have something to compare, and I can't stress this enough, these are all wonky numbers, so let's make our life a little easier and divide : Number of neurons ~ 86 Billion, Number of Synapses ~ 150 Trillion, another generalization: average number of synapses per neuron ~ 1,744. So now let's look at the brain, and again this are all contested numbers. The number of neurons in AI systems is a little tricky to calculate, Neural Networks and Deep Learning are 2 current AI systems as you call them, specifics are hard to come by (If someone has them please share), but data on parameters do exist, parameters are more analogous to synapses (connections) than neurons (the nodes in between connections) somewhere in the range of 100-160 billion is the current upper number for specialized networks.ĭeriving the number of neurons in AI systems from this number is a stretch since these AIs emulate certain types of connections and sub assemblies of neurons, but let's continue.
