Machine-Learning Maestro Michael Jordan on the Delusions of Big Data and Others
These two comments seem to contradict each other:<p>"we have no idea how neurons are storing information, how they are computing, what the rules are, what the algorithms are, what the representations are, and the like."<p>"...you get an output from the end of the layers, and you propagate a signal backwards through the layers to change all the parameters. It’s pretty clear the brain doesn’t do something like that. "<p>So why can't the brain do some kind of backpropagation?
