Warning: this assignment is out of date. It may still need to be updated for this year's class. Check with your instructor before you start working on this assignment.

The final project is due on Tuesday, May 11, 2021. Late days are not allowed for this assignment.

Final Project : The End

The end is in sight. This will be the final deliverable for NETS 213. This assignment will be worth 20% of your final grade. The goals of the final deliverables are the following:

  • Show off what you did and why it is cool
  • Demonstrate how it relates to the course and what you learned
  • Analyze your results- is it better than similar/existing approaches? What more could be done?

Final Video

On the day of the final exam, you will each have 7 minutes to wow everyone with your finished product. We will ask you to do so in a 7 minute video. You all have a lot of work to showcase in those 7 minutes, so you keep it crisp and on-point. Your video should:

  1. Motivate the problem you are trying to solve or question you are trying to answer, and why crowdsourcing is an especially good fit for solving/answering it.
  2. Give a quick background on related problems. Have others tried to solve the same problem? What makes your approach different/better?
  3. Demo your solution/product. If you built an app, show it off in all its glory; if you conducted a scientific study, explain your procedure and demo the crowd-facing components.
  4. Describe your method/algorithm. Make sure you address the issues of incentives, quality control, and aggregation. Which components you focus on will differ depending on your project, so you don’t have to give each one equal weight. Touch on each one, but focus on the part that was the most challenging or required the most creativity.
  5. Discuss your results. Convince us that what you did “worked”. What is the take-away?

Some other tips for making your video awesome:

  • Your video should be able to stand alone; someone with no knowledge of the class should be able to watch it and understand what you did and why it was a worthwhile thing to do. This will make it a more rewarding capstone of your work this semester.
  • Every project is different- focus on what makes yours cool/interesting/exciting/impressive. If yours was engineering-heavy, spend the majority of the time on step (3). If yours was more scientific, you should spend the majority of the video on (5).
  • Show, don’t just tell. Demos of working apps or figures of analyzed results are gold. Don’t just use your voice-over to read words off of a slide.

Final Report

Five minutes is short, and we want you do use your video to showcase what is great about what you did. So to make sure you still get credit for all the obligatory parts, and because it is only fitting, we will have you fill out a detailed final report. The questions that we ask you to address will look familiar - its okay to reiterate points you made on past checkpoints, but highlight what about your original plan changed in your final product.

The questions we will ask you to answer in your final report are , includes questions about these topics:

  • What problem you are solving/question you are answering
  • How you attempted to solve/answer it
  • How did you address each of the following: incentivization, aggregation, QC
  • Did you project work? How do you know so? Analyze some results, discuss some positive outcomes of your project.
  • What are the biggest challenges you had to deal with? What changed between your original plan and your final product?
  • What are some limitations of your product. If yours is an engineering-heavy project, what would you need to overcome in order to scale (cost/incentives/QC…)? If yours was a scientific study, what are some sources of error that may have been introduced by your method. If you results deviate from previous work, why might that be?

Your final report should do a deeper analysis of the individual components of your project. You should pick two of the sections to do a deeper analysis on. For the two deeper analyses, we ask you to create a graph. Which questions you should pick depends on where the balance of your team’s effort went. Some people are building really complex system that require a lot of engineering. Other people’s focus is on analyzing data. If your focus is on analysis, then you should generate more in-depth graphs.

Final Presentations

The final project presentations will be held during the final exam slot. We will play your videos and have a short amount of time for you to answer questions from the audience.

Final report

Below are the questions that you should address in your final report. lease submit your answers in a PDF that you submit to Gradescope.

  • Did you perform any analysis comparing different incentives?
  • If you compared different incentives, what analysis did you perform? If you have a graph analyzing incentives, include the graph here.

What the crowd gives you

  • What does the crowd provide for you?
  • Is this something that could be automated?
  • If it could be automated, say how. If it is difficult or impossible to automate, say why.
  • Did you train a machine learning component from what the crowd gave you?

  • Describe your crowd-facing user interface. This can be a short caption for the screenshot. Alternately, if you put a lot of effort into the interface design, you can give a longer explanation of what you did.

Ethics

Your report should include a discussion of ethics. One method of address this requirement is to nominate one of your teammates to ask ethics question of the whole group.

  • Should my application exist at all?
  • Does this task potentially expose workers to harm (for example, content moderation)? What effect can it have on them?
  • Are you fairly compensating the workers for their time?
  • If you are creating a dataset for machine learning: ** Are you allowed to access the data that you’re labeling (have you ensured that it isn’t private data)? ** Is there the potential for introducing bias in your machine learning classifer (unintended discrimination against a group because of underrepresentaiton)? ** ML algorithms sometimes amplify bias in the training data. What would be the consequences if this happens in your ML system?
  • Is your evaluation sound? Do the conclusions you reach stand up to scientific scruitny?

Quality Control

  • Is the quality of what the crowd gives you a concern?
  • How do you ensure the quality of the crowd provides?
