Types of Computing Bias - Tarun

  • Data Bias: The data does not accurently represent the values of the real world ex. If data is taken from a sample size that doesn’t reflect the actual population - If you wanted data to represent the population in America but your sample that is being surveyed is from a Texas. The population in Texas does not accurately reflect the entire population of America.
  • Human Bias: Those who make programs may be influenced by their own biases ex. If a development team are experts in using a certain language and their algorithm demonstrates that language, they will feel that people who specialize in that language are qualified and better. This is essentially bringing in their personal biases and applying to a larger amount of people.

Explicit data vs Implicit data: - Pranavi

Explicit data:

  • takes the data that you give
  • When watching a video, and it asks “are you enjoying this?”, and you respond with either a thumbs up or down, you are giving them explicit data

Implicit data:

  • When you watch or search up certain things, data can be deduced on what is the “norm” for the person

Example: Netflix

  • When browsing through Netflix, they show Netflix exclusives, they do this because they want your subscriptions
  • showing the netflix exclusives is the bias in this scenario

In what other applications could have intential bias?

Intentional Bias vs Unintentional Bias - Tanvi

Example 1: Hypothetical Loan company

  • Suppose a software was created to assist loan officers, and certain trends of successful loans were taken
  • If people are rejected of those who don’t fit in their trends of either age, gender, race, etc.
  • This software is biased in the way that it only chooses candidates who will have higher chances in successful loans

Example 2: Candy Crush vs Call of Duty

  • Call of Duty is geared towards the teenage boy demographic, 18-24, with more grunge type of music
  • Candy Crush is more visually appearing to younger audience as it includes pictures of candies and playful music
  • This is biased as the games include aspects and characteristics that will seem appealing to a specific audience

How is their unintentional bias in apps such as TikTok or Instagram or otehr social media apps?

Mitigation Strategies - Shubhay

  • Utilize data from various sources
  • Pre-Processing: A way to check the inputs for bias before it is being used as data
  • In-processing: This algorithm changes the data during analysis of the data to keep the data consistent
  • Post-Processing: # step check to make sure the model is fair and accurate
    • Input Correction: This strategy makes adjustments to the data to make the data more comparable
    • Classifier Correction: polishing and adjusting the algorithm after it has been trained to reduce the biases
    • Output Correction: The predictions made by the model is modified to eliminate biases

Homework:

  1. Is bias enhancing or intentionally excluding? Bias can be enhacing at times, for example an online website may provide results to a person which they want to see. In this scenario, it is enhancing, since people are shown what they are looking for only and better improves the website. Other times, unintentional bias in games may target a specific demographic based on the game’s topic and graphics. This while not excluding people from a game, makes it more likely to be played by a certain demographic, which may be beneficial or harmful for them.
  2. Is bias intentionally harmful/hateful? Bias is usually placed in a website to improve the quality of the website for the user, and is therefore usually helpful. While in extreme cases bias may be placed in a website to exclude people this is no different from a real life event like a hate crime, which is such an edge case.
  3. During software development are your receiving feedback from a wide variety of people? During our past project we did peer reviews and collaborated with and got feedback from a variety of people.
  4. What are the different biases you can find in an application such as Youtube Kids? Videos on the website are likely targeted towards a younger audience, and things like disabling comments are also targeted towards a younger audience, preventing potentially harmful intervention. The channels and ads are also likely subject to bias as well, as a result of the younger audience.
