Justify your answer by calculating whether the probabilities involved satisfy the definition of conditional independence. We will also assume that Jacob's call and Mark's call are conditionally To express the dependence of the random variable alarm on its parents burglary and earthquake, we use one Prolog rule for every possible state of the parents. 77, when it was a very low probability before. Given the evidence of who has or has not called, we would like to estimate the probability of a burglary. You live in the seismically active area and the alarm system can get occasionally set off by an earthquake. The alarm responds to detecting a burglary and also to minor earthquakes. Burglary (B) and earthquake (E) Example I'm at work, neighbor John calls to say my alarm is ringing, but neighbor Mary doesn't call. 003 Mixed inferences Setting the effect JohnCalls to true and the cause Earthquake to false gives ¬ These arguments specify a combination C1 of events whose probability we want to compute. Similar change occurs with Burglary. . Is there a burglary? If we observe $ {Alarm} { {,=,}} {true}$, are $ {Burglary}$ and $ {Earthquake}$ independent? Justify your answer by calculating whether the probabilities involved satisfy the definition of conditional If we observe Alarm = true, are Burglary and Earthquake independent? Justify your answer by calculating whether the probabilities involved satisfy the definition of conditional Alarm system example Assume your house has an alarm system against burglary. a) If no evidence is observed, are Burglary and Earthquake independent? Prove this from the numerical The network structure is showing that burglary and earthquake is the parent node of the alarm and directly affecting the probability of alarm's going off. David and Sophia's calls depend on alarm From a topological semantics perspective, we can use the concept of disjoint sets to show that burglary and earthquake are independent. Sometimes your alarm is set off by minor We need to multiply the individual probabilities of burglary, the alarm sounding given burglary but no earthquake and neither David nor Sophia calling Harry. 2 of the textbook. 1. For example, in the first example above, C1 = (Burglary=true and Alarm=false), and in the second SOLVED: John has installed a burglar alarm at his home. n this equation, we know that Radio is independ de is conditionally independent of all its predecessors in the ordering gi 2.

Justify your answer by calculating whether the probabilities involved satisfy the definition of conditional independence. The document repeatedly asks if burglary and earthquakes are independent given no evidence or if the alarm is true, and asks to prove independence from numerical and topological semantics or by As Alarm is influenced by both Burglary and Earthquake, knowing that the Alarm is true gives information about the likelihood of both events. o Show that when no evidence is observed, Burglary and Earthquake are independent. b) If we observe Alarm = true, are Burglary and If we observe Alarm — true, are Burglary and Earthquake independent? Justify your answer by calculating whether the probabilities involved satisfy the definition of conditional independence. You know an earthquake didn't happen, because the probability of the alarm going off at exactly the same time for an earthquake and a burglary is zero. Is there a burglar? Variables: Burglar, Earthquake, = a burglary occurs at the house = an earthquake occurs at the house = the alarm goes off = John calls to report the alarm M = Mary calls to report the alarm Suppose Burglary or Earthquake can trigger To model this as a Bayesian network, one would use three random variables, burglary, earthquake and alarm, with burglary and earthquake being parents of alarm. Example Burglar alarm at home Fairly reliable at detecting a burglary Responds at times to minor earthquakes If we add evidence that Earthquake is true, then P(Burglary | Alarm ∧ Earthquake) goes down to 0. Figure 9: The Bayesian network for the burglar alarm example. My two neighbors, John and Mary, promised to call me at work if they hear the alarm Example inference tasks Suppose Mary If we observe A l a r m , = , t r u e , are B u r g l a r y and E a r t h q u a k e independent? Justify your answer by calculating whether the probabilities involved satisfy the definition of conditional Explain why using the rules of d -separation. 2. Knowing whether there has been an Earthquake does not suffice to determine the probability of an earthquake, we have to know whether there has been a burglary as well. Wn I have a burglar alarm that is sometimes set off by minor earthquakes. The α b denotes the reliability of the alarm in case of a burglary and the earthquake triggers the alarm with a probability of Alarm system example. The document defines a Bayesian network model to analyze the probabilities in a burglary alarm example. Is Radio conditionally independent of Burglary given Alarm? Answer: No. This is because all other descendent earthquake. [10 pts Baysian Network: Independence (a) [Spt] If we observe Alarm - true , are Burglary and Earthquake independent?

Then, Alarm is the only parent If we observe Alarm = true, are Burglary and Earthquake independent? Justify your answer by calculating whether the probabilities involved satisfy the de nition of condi-tional independence. Burglars and Earthquakes You are at a “Done with the AI class” party. Thus, observing Alarm = true breaks the If we observe Alarm = true, are Burglary and Earthquake independent? Justify your answer by calculating whether the probabilities involved satisfy the definition of conditional independence [1]. We obtain these probabilities Other assumptions: neighbors do not perceive burglary directly and they do not notice minor earthquakes neighbors do not confer (they are independent) 1. If I recall, this example forms a graph with (earthquake, burglary) being the two parents of a child (alarm), and the statement is that the two parents are conditionally independent only when If we observe $ {Alarm} {true}$, are $ {Burglary}$ and $ {Earthquake}$ independent? Justify your answer by calculating whether the probabilities involved satisfy the definition of conditional independence. Assume your house has an alarm system against burglary. It .
