Frequently Asked Questions (FAQ)

Project homepage

For project related questions:

  • Please contact Peter ([email protected]) sent by your ITSC email account (@ust.hk)
  • Email title format: [COMP3111 Project] Write your question in short
  • Email messages other than the above format will not be answered

Question: What is the difference between data filtering and data transformation? Do we need to pick one from each?

act2 feature5

Data filtering is the task of reducing the content of noise or errors from measured process data. Data transformation is the process of converting data or information from one format to another. In feature 5, the first 2 operations are data filtering techniques and the last 2 operations are data transformation techniques.

TWO types of Data Filtering and Transformation from the table refer to:

  • Implement 1 filtering and 1 transformation OR
  • Implement 2 filtering technqiues OR
  • Implement 2 transformation techniques

Question: How many comparison operators in feature 5 - Filtering numeric data?

act2 feature 5

Comparison operators are (>, >=, ==, <=, <, !=). However, if you implement one, the rest is very easy to implement. We expect teams to implement all of the above comparison operators.

Question: What to submit for the workload distribution in activity 1?

act1

It is just a simple table indicating how the features are assigned. In the Google Spreadsheet, I observe that not every group makes the feature assignment yet. We should finalise it in Activity 1. Once it is set in the activity 1, no further changes are allowed.

Question: Why implementation classes are included in the UML Lab?

act1 uml lab4

The UML lab is designed to help students learn the skills and tools to draw UML diagrams, but not the correctness of the UML diagrams. Given the problem domain, the correctness and appropriateness of drawing UML diagrams was thoroughly discussed in the lecture. In other words, please don't regard the UML lab result as the sample solution of the Activity 1.

Question: What things and How to submit Activity 1/2?

act1 act2

The submission details and deadlines can be found in Canvas. In short:

  • each student needs to submit a PDF in Activity 1, and
  • each team, represented by the team leader, needs to submit a private GithHub URL in Activity 2

Question: Any format for meeting minutes and Gantt chart?

act1 minutes Gantt chart

  • Meeting minutes: A template is provided
  • Gantt chart: It is flexible to use any tool (e.g. Excel, other online tools, ...) to draw a Gantt chart, which is just a variation of bar chart. Suggestion: x-axis (date), y-axis (tasks/sub-tasks), bars with 3 different colors representing 3 different team members

Question: About Animated Chart.

Should we use one of the two decided charts and make it into an animation? Or should we put animated chart as a separate generalization for a chart class?

act2 feature 6

There is no restriction. Teams can decide to implement multiple separated chart classes, or a generalized chart class with multiple subclasses, or an animate method in a chart.

Question: About Data Filtering and Transformation

Do we only need to implement 2 out of the given 4 algorithms?

act2 feature 5

Yes. Select any 2 out of the 4 algorithms in the table.

Question: GitHub education account

GitHub rejects our application due to the reason that it cannot verify our academic status. How to solve it?

github git

You may use a personal email account to create a GitHub account. Check the following items:

  • Visit the "GitHub email settings page" and add your ITSC email
  • You are expected to receive a verification email. Please click verify in that email.
  • After that, you can go back to GitHub Education and re-apply.

Question: Attribute visibility

For the COMP3111 Project activity 1(UML diagram), do we have to show the visibility for each attributes (i.e. +, #, - next to the attributes of classes)?

act1 uml class diagram

Class attributes and operations should be included. Example in slide 15-16, UML Modeling 1 lecture

Question: Assignment 1 submission detail

Does it mean that UML class diagram(and use-case) for each member has to be different or all the members are expected to submit the same work?

act1 uml use case diagram class diagram

The UML class/use-case diagram can be the same, or can be different. It won't count as plagiarism as the diagrams are agreed by the whole team. In any case, assignment 1 is an individual assessment.
