Question 2: | A biometric system consists of two subsystems: face and fingerprint. The following values have been obtained for the two subsystems separately: FMR (False Match Rate) FNMR (False Non-Match Rate) Face subsystem Fingerprint subsystem 8% 10 % 4% 14% Suppose that the subsystems decisions are combined as follows: The outcome of the combined system will be a match only when the outcomes of both of the subsystems are matches. When the outcome of either subsystem is a non-match, the outcome of the combined system will be a non-match. a. Compute the FMR and FNMR values of the combined system? b. What are your conclusions about the performance of the combined system?

Suppose that Iris and Kelvin are involved in a romantic relationship, unknown to anyone else in the company. Romantic relationships between employees are not against company policy, but married employees are specifically prohibited from being in a direct reporting relationship with each other. Should Iris inform Charlie about her relationship with Kelvin if she does not plan to apply for the transfer? If Iris does apply for the job but has no current plans for marriage, should she inform Charlie of her relationship?
Every information retrieval (IR) system is either directly or indirectly connected to a certain theory of how information is obtained. The IR model of the IR System is informed by these several hypotheses. There are several IR models to choose from. When compared to the probabilistic IR model, how does the vector space IR model fare?
It's a Machine Learning question. Suppose we have market basket data consisting of 100 transactions and 20 items. Compute the total number of possible association rules. If the support for item A is 25%, the support for item B is 90% and the support for itemset {A,B} is 20%. Let the support and conﬁdence thresholds be 10% and 60%, respectively. Compute the conﬁdence of the association rule {A} → {B} & {B} → {A}.

1. Considering the CIA triad and the Parkerian hexad models, what are the advantages and disadvantages of each model? (This question may be answered in Table format.) 2. Describe the CIA triad principles and also the Parkerian hexad principles that are affected in the following situation: Using the medical office which has been used as our example in the slides, they are sending a backup disk of personal and payment information for their customers that is encrypted to an off sight location. The disk is being transported via a carrier to the storage facility is lost. In addition to listing the triad and hexad principles affected in this scenario, provide an explanation for why or why not each principle is affected/not affected.
