Theories about the genetic origins of altruism suggest that evolution should only favor altruism when it is directed toward family members. Assuming such theories are correct, which of the following choices best explains the fact that people nonetheless do behave altruistically, sometimes astonishingly so, toward strangers?

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.

Question Set 3 – 3.7 You can also use the attack countermeasure tree (ACT) to model the attack scenarios. For example, Figure 3.4 presents a BGP attack scenario. In the figure, the money value ($) are used to represent how much effort an attacker needs to expend to deploy the attack. Referring to Figure 3.4 and if the attacker’s budget constraint is $2900 (so the sum of the effort spent by the attacker cannot exceed $2900 ), which attack scenarios are possible?

Question Set 4 – 4.4 The list below presents the procedural steps of FNN. Which of the answer options presents their correct order? STEP A: Input the first observation of your dataset in the input layer, each feature in one input node. STEP B:Compare the predicted result to the actual result. Measure the generated error. STEP C: Forward-propagation: from left to right, the neurons are activated in a way that the impact of each neuron’s activation is limited by the weights. Propagate the activations until getting the predicted result y. STEP D: Randomly initialize the network, set weights to small numbers close to 0 (but not 0). STEP E: Repeat previous steps and update the weights after each observation. Or, repeat previous steps but update the weights only after a batch of observations (Batch Learning). STEP F:Back-Propagation: From right to left, the error is back-propagated. Update the weights according to how much they are responsible for the error. The learning rate decides by how much we update the weights.
