question number 2 pleaseAssignment OO Programming Sem 2   2021  Java The aim of this assignment is to develop a java application  that puts into practice the  programming skills taught on your OO programming course.   You have two  options for your project:  • You can pick one of the ideas described in this document. This is the most typical option.  • You can create your own idea e.g. a game, some sort of analysis tool,  etc of your choice  – but you need to get your idea approved first, to check it’s suitable.  This assignment is worth 60% of your Sem 2 CA (and therefore, 30% of your OVERALL CA  mark. What next?  If you are doing one of the 4 ideas below  - just go ahead and get started.   If you are doing your OWN project idea, please submit a description of your idea to me by  Friday March 19th.  Your idea must have some sort of algorithm in it – just as the sample  projects shown here do – so keep that in mind. You should divide it into the core  functionality, and the optional advanced features.  I will approve the project or send it for  redrafting if it is not suitable. The sooner you send it to me, the sooner you get it returned. Assignment criteria  As well as meeting the requirements of the application:  • All or most of your assignment should be written in Java.  If there are extra parts  (e.g. database) that is fine.   • Your code should demonstrate the use of OO concepts. -  including using classes for  separate entities (as opposed to dumping everything into a single class), methods,  encapsulated attributes, constructors,  inheritance, interfaces, polymorphism.   • Code should follow java naming standards, be well indented, bracket aligned ,  comment headers, comments.  • Use BitBucket or GIT to manage your source code.  Your code and video link will be  collected from your whatever code repository you use (more on this).  If you haven’t  used GIT, we can cover in class.   • If you make use of any code directly from a book or online source, you must show  this in the comments. You will be marked on code that is your own code.   • The assignment is due in on by end of day Monday 19th April  Assignment OO Programming Sem 2   2021  Java What you submit:  - Code (either as  zip file or repository link);  - Video: 3 minutes or less, in which you demo all of your app.  Show each screen being  used, explain what data you are entering or what you are clicking, any error checking  etc. as if you were demo’ing in person.  Just show your screen with your voice - as  opposed to you!  - Readme file: Include a readme file to explain your project. This should list:  o List of classes, with a description.   o Description of the core functionality you included;  o Description/list of the optional functionality you included.   o Explain what you would add if you had more time. Marking  The marking scheme will be:  - 10% Project management (demonstrating regular commits using GIT over the lifetime of  the assignment)  - 10% video (and read me file) explaining your assignment – available via YouTube or any  video hosting service   - 40% Basic core functionality: for well functioning, well implemented, using code that  follows coding standard core functionality – i.e. the core of whatever problem you are  solving.  - 40% Optional advanced features: for added functionality that enhances whatever your  idea is. Plagiarism means attempting to pass off someone else’s work  as your own or deliberately allowing another student to copy your work  Be careful: IF YOU COPY YOUR ASSIGNMENT, YOU GET ZERO PLUS  & IT GOES ON YOUR  RECORD The following four ideas are available to choose from : Assignment OO Programming Sem 2   2021  Java 1. Machine learning model, using Naïve Bayes   This assignment allows you to learn about machine learning, including building a  predictive/classification model. The machine learning classifier you will use is Naïve Bayes.  The purpose of the assignment is to build a prediction tool that predicts whether a  secondary school pupil will become an entrepreneur or not (i.e. own their own business) in  the future.  The model uses previous examples of secondary school students and whether  they later became entrepreneurs or not – and has information such as whether the student  studied “business subjects”, had a part time job, had a guardian/ parent who owned their  own business and student gender.    Using java, the assignment should “train” a model using the dataset provided.  Don’t hard  code the classifier in anyway – make sure it is driven by the data dynamically in your code.  Using a GUI, allow for student’s details to be put entered in, and the prediction model will  give the probability of whether they are likely to be an entpreneur in the future.    To make this work well , you will need to have a GUI to take the new input (student details)  that you want to predict about.   • Have the application read in the training set and do the training dynamically  (i.e. don’t  hard code the rules for the classifier).    • If extra data rows, termed “instances” are added to the dataset, your classifier should  still work (in fact, it will be improved as a result of new data).   • Allow for model to train on some of the dataset (e.g. 70%) and test itself on the  remainder of the dataset(30%) so that it knows how “good” it is (i.e. be able to evaluate  itself).         Dataset Columns: (Full dataset will be put on Brightspace)  Features: Student gender,   Features The label  Student  gender  Parent/  guardian  had own  business  Has  a  part  time  job  Urban  or rural  address  Studies  business  subjects  Become an   Entrepreneur  Female Yes No Rural No Yes  Etc             Assignment OO Programming Sem 2   2021  Java 2. Topic Modeller This tool will allow a user to detect whether a set of documents are “about” the same topic  or not.   The tool will analyse the words in each document – and decide what the most common  words are in each document.    “Stop” words should be excluded from the analysis (this is the list of words that don’t really  add meaning which are not included in the similarity measure – such as “the”, “a”, “of”  “he”.. etc.  Sets of stop words can be found online (for example at :  http://www.lextek.com/manuals/onix/stopwords1.html)   Basic on the overlap in the top X words (e.g. 10), a grade of likelihood of it being about the  same topic can be produced (e.g. 70% overlap in the top ten words = 70% likely to be about  the same topic or whatever way you decide to do this).  Likewise, documents with small  overlap on most comment words (e.g.
