Question 5Suppose you want to use a GNN to classify the nodes of a social network (for example, the classesmay be: "Democrat", "Republican", “Undecided", "Other"). Suppose that you know the correct label(i.e., the political affiliation) for some of the nodes. Additionally, you know some additionalattributes (gender, age, education level) for all nodes. Which of the following statements is/arecorrect?The known node attributes, together with the political affiliation data, can be used to form the embedding ofeach node at layer-O.O The training data should consist of all nodes for which we know the political affiliation.O The larger the number of layers (depth) of the network, the more susceptive the network is to overfitting.O The network can be trained with the cross-entropy loss function we presented in class.

Consider a database that holds information on students assessment. Students are assessed on a particular course by taking four exams. Each exam is the only assessment for a module on which they have enrolled. Students from different courses share the same module. Exam marks for a particular student are entered in sequence. A report is generated at the end-of the semester with the following columns. Student_ID, Average_mark, Student_name, Grade Date Assessed, Use the above information to derive a simple class (Object Oriented) model using UML notation.

Assume that we have four classes: Person, Teacher, Student, and PhDStudent. Teacherand Student are both subclasses of Person. PhDStudent is a subclass of Student.A.Which of the following assignments are legal, and why or why not?Person p1 = new Student();Person p2 = new PhDStudent();PhDStudent phd1 = new Student();Teacher t1 = new Person();Student s1 = new PhDStudent();Suppose that we have the following legal declarations and assignments:Person p1 = new Person();Person p2 = new Person();PhDStudent phd1 = new PhDStudent();Teacher t1 = new Teacher();Student s1 = new Student();B.Based on those just mentioned, which of the following assignments arelegal, and why or why not?s1 = p1;s1 = p2;p1 = s1;t1 = s1;s1 = phd1;phd1 = s1;
Consider this scenario, a mehtod in some class needs to access a data field in another class, here are two possible implementations: public class Process { /* * Check if student qualifies for financial help */ void check(Student student) { //.... } /* * Check if student qualifies for financial help */ void check(double studentGPA) { //.... }} In class Process, which check method you think is better, why? In other words, should we pass the object to the method or just the data member it needs? Disucuss the Pros and Cons of each approach (if any). Assume class Student has a mehod called getGPA( ).

The category need to have a para motorized constructor and a technique to compute its area. Now make a ring object in a driver type (with any values) and print it vicinity the use of the method.
Using UML class diagrams, create a design for the following (you can defer declaring the types for any instance variables and instance methods as long as you represent the concepts appropriately). NB: You may hand-draw your diagram or use a drawing program (your choice). Upload your finished answer for (a) and (b) as one file. (a) An Employer has one or more Employees. An Employee has exactly one Employer. Employees have attributes for their name, salary and job title (b) We are producing a vehicle registration system for the local DMV/RMV. Model the following using a UML class diagram. Read the entire specification before proceeding (this is ONE question, broken into 4 segments for readability): (i) Our interface (protocol/contract) IVehicle states that all vehicles can register() and calculateExciseTax(). These operations are public and the Vehicle contract is stable – it will not change. (ii) We think we’ll be able to take advantage of code-reuse, so your team must introduce an…

1. Use Argo UML to draw the following: a. Class 'Employee that has the following attributes (name, address, phone). b. Class 'Teacher' that has attributes (ssn, email, title) and one method to print the previous information. c. Class 'course that has attributes (Id, name, code, detail) and one method to print the previous information. d. Make relationship between the class Teacher' and 'course' as many teachers teaches many courses. e. Class 'Teacher' inheritance its information from class 'Employee'.

When one class includes objects that belong to another class, this is known as a whole-part relationship or composition. The conclusion is that a has-a connection exists. Consider the following lengthy assertion: getHireDate(), getYear(), and Outputsales.getHighestPaidEmployee() are some useful functions ().
