Question
3. In your local nuclear power station, there is an alarm that senses when a temperature gauge exceeds a given threshold. The gauge measures the temperature of the core. Consider the Boolean variables A (alarm sounds), FA (alarm is faulty), and FG (gauge is faulty) and the multivalued nodes G (gauge reading) and T (actual core temperature).
a. Draw a Bayesian network for this domain, given that the gauge is more likely to fail when the core temperature gets too high.
b. Is your network a polytree? Why or why not?

- The following MDP world consists of 5 states and 3 actions: (1, 1) (1, 2) Action: Exit - -10 Actions: down, right (2, 1) (2, 2) Action: Exit = -10 Actions: down, right (3, 1) Action: Exit = 10 When taking action down, it is successful with probability 0.7. with probability 0.2 you go right, and with probability 0.1 you stay in place. When taking action right, it is successful with probability 0.7, with probability 0.2 you go right, and with probability O.1 you stay in place. When taking action Exit, it is successful with probability 1.0. The only reward is when taking action Exit, and there is no discounting.

For a variety of a decent numbers a, one discovered that the amount of approximately two adjoining components is equivalent to x (for example x=ai+ai+1 for some I). x had ended up being a decent number too. Then, at that point, the components of the exhibit a were worked out in a steady progression without separators into one string s. For instance, assuming a=[12,5,6,133], s=1256133. You are given a string s and a number x. Your undertaking is to decide the situations in the string that compare to the neighboring components of the cluster that have total x. In case there are a few potential replies, you can print any of them. Input :The primary line contains the string s (2≤|s|≤5⋅105). The subsequent line contains an integer x (2≤x<10200000). An extra imperative on the input: the appropriate response consistently exists, i.e you can generally choose two nearby substrings of the string s so that in the event that…arrow_forwardGiven that P(x, y, z) is a propositional function such that the universe for x,y,z is {1,2}. Furthermore, suppose that the propositional function is true in the following cases, namely: P(1, 1, 1), P(1, 2, 1), P(1, 2, 2), P(2, 1, 1), P(2, 2, 2); and it is false, otherwise. Therefore, deter- mine the truth value of each of the following quantified statements, viz: (a) VxVyz(x, y, z) (b) Vx³y³zP(x, y, z) (c) VzxP(x, y, z) (d) xyz(x, y, z)arrow_forward
- Lets say a graph Plotted are the acoustic vowel spaces for a female speaker producing clear and casual/ conversational speech. As the graph may show, this speaker produces a larger vowel space during clear speech versus conversational speech. i. What consequences may this acoustic modification have on intelligibility? ii. How might vowel space expansion be viewed as a direct consequence of reduced speaking rate?arrow_forwardSuppose we have a neural net, which we denote as a function F(x; 0), that performs binary logistic regression to classify between images of cats and dogs. The final layer of F is a sigmoid, so that the output is a number between 0 and 1. Cats are given the label 0, and dogs are given the label 1. We use the NLL loss as our loss function: L(F(x; 0), y) = − [y log F(x; 0) + (1 − y) log(1 – F(x; 0))] We have an image x under consideration and wish to modify our predictions about it. Is the following true? If we want our net to predict 'cat' we should try taking a gradient step new = x − ▼xF(x; 0).arrow_forward3.

- The supervised classification algorithm you pick will usually output a real-valued score, and you will decide upon to select out a threshold or thresholds above which to block the exercise or exhibit off increased friction. How do you select out out this threshold?

Suppose you have n samples with their respective areas, x(1), x(2), ... , x(n), their true house rents y(1), y(2),..., y(n). Let's say, you train a linear regres- sor that predicts f(x()) = 00 + 01x(e). The parameters 6o and 0, are scalars and are learned by minimizing mean-squared-error loss with L2-regularization through gradient descent with a learning rate a and the regularization strength constant A.
