Question Set 4 – 4.1 Deep learning has been used to establish an anomaly detection model. The infrastructure of a biology-inspired neural network for building anomaly detection models can be illustrated as shown in Figure 4.1 below. More specifically, this figure illustrates a feedforward neural network (FNN) that can generate normal or abnormal traffic behavior patterns using supervised or semi-supervised ML strategies. In this model, network traffic can be first categorized by multiple features, which later will be used as inputs of the FNN. The following questions are based on the presented FNN neural network solutions. Recall that a neuron contains an activation function ϕ(∗). Which of the following statements regarding the activation function are correct? (select all that apply) Figure 4.1.
