QUESTION-1 A) Illustrate how the process of deduction works using facts and rules in a rule based system. (You can use Forward Chaining or Backward Chaining). B) Why Knowledge Acquisition is difficult in KBS development? How can we make it easier? Note Please Please Please give me best correct answer Clearly.

What distinguishes a variable reference model from a variable value model? Why is it important to distinguish between them?

COCOMO Exercises 1. Assume that a system for simple student registration in a course is planned to be developed and its estimated size is approximately 10000 lines of code. The organization is proposed to pay RM1300 per month to software engineers. Compute the development effort, development time, and the total cost for product development. 2. Supposed a library management system (LMS) is to be designed for a university. From the project proposal, the following five major components are identified: Online data entry Data update File input and output Library reports Query and search 1.0 KLOC 2.0 KLOC 1.5 KLOC 2.0 KLOC 0.5 KLOC The database size and application experience are very important to this project. The use of the software tool and the main storage are highly considerable. The virtual machine experience and its volatility can be kept low. All other cost drivers have nominal requirements. Estimate the development effort and the development time. 3. A project size of 200KLOC is to…

The Ghana health service requested for a machine learning model to detect the presence of a new disease based on symptoms present in a blood sample. You have been selected to be part of the team responsible for the development of the model. Belo is a block diagram of the system. Inputs Processing Output The accuracy in the output depends on the correct inputs. The model designed is supposed to be evaluated to determine the accuracy and it is supposed to function in a supervised way. Hence the data sets can affect the model and vice versa. Given P(Data|Model) = P(Model|Data)P(Data) or P(DIM) - p(Model) P(M|D)P(D) show that the p(M) following statements are true with a formal mathematical proof. Show that P(M|D)P(D|M')(1-P(M))+(1-P(D|M)P(M))| a. P(D|M) = 1-р(м) b. P(D) = P(D|M')(1 – P(M)) + (1 - P(D'/M)P(M) )
