Neural Networks Non-Linearity: (In response to a question asked) 1 st – We’ll define a non-linear system as one in which the outputs are not proportional to the inputs. NN’s incorporate non-linearity at each neuron by means of the neurons activation function which is typically a sigmoid. (sigmoid meaning curved like the letter C or curved like the letter S). More on this later.

Elements of a Neuron Model 1 - Synapses or Connecting links : it is at these sites that input enters the neuron. Each synapse has an associated weight. This weight will multiply the input prior to entering the summing junction (to be discussed next).

Elements of a Neuron Model 2 – An adder (linear combiner) for summing the input signals (which have been weighted by their respective synapses prior to entering). This is our summing junction .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
