@trojanfoxtrot Probably equation for output of a neuron as in a #neuralnetwork. The sigma may represent using the "sigmoid" activation function, whereas the term inside the parens in a bias term, b, plus a weight sum of the inputs. Was this a handout at some #machinelearning conference?
@danielledoesdata hmm that makes a whole lot of sense. I really appreciate the explanation,thanks!
It was a handout at #DEFCON this year from one of the #hardwarehacking vendors and the backside is embroidered with “Skynet” and the logo.
