A Perceptron's output value y is often based on the activity function. This output may then be modified by another function or functions such as the activation function and/or a threshold logic function. Select the answer that best explains the utility of using these functions and why they are used in some situation and not in others. Only one answer is the best answer and you should read each possible answer carefully. O The activity, activation and threshold logic functions are used to model biological and mathematical aspects of perceptrons and their use is dictated by what particular problem being modelled. mathematically convenient and/or necessary for the O The activity function is the best way to capture the idea of changing the level of importance or significance of an input that is "on". O The activation function along with threshold logic functions can model the action potential of a biological neuron. O The threshold logic function can be used to model binary logic functions. QUESTION 6 Sometimes we want to model output as a binary value; that is, a function that produces only one of two possible values such as 0 and 1. Sometimes we want this property to have additional mathematical characteristics that involve combining two outputs. In the binary example, two different outputs (0 and 1) can be combined using certain mathematical operations to produce a 0. Select the answer that show how to use a basic mathematical function that mimics a logic operation. Oy=1+/2 where I, and Iz are either 0 or 1. Oy=,®12 where Iz and Iz are either 0 or 1. Oy=1, x12 where Ij and Iz are either 0 or 1. Oy =, +12 where Ij and Iz are either 0 or 1.
