AI models trained with biased data

AI models trained with biased data

Data bias can have notable implications for research and practical applications. For example, in a Facebook scandal, its AI shockingly asked users if they wanted to continue seeing videos about primates after watching a video featuring Black men.

Data bias refers to data sets that don't represent the population in study. Models trained on biased data could contain prejudice. That's why AI Researchers and Data Scientists must be vigilant to ensure models don't contain any bias.

Collect data from a variety of sources.

The most common avenues for collecting training data:

  • Paying for data sets
  • Using public data sets
  • Sourcing open source content
  • Using in-person or field-collected data sets

A combination of all four will provide the best training data.

Ensure diverse data

Ensure diverse data

Ensure the data is diverse. Speakers in the audio or video files should possess a range of characteristics, including locations, dialects, genders, sex, race, and nationality.

Sourcing such data could be difficult if you only rely on open-source data.

Monitor real-world performance

Once you've ensured your initial data set is diverse, your model can still have bias.

That's why you should monitor your model's real-world performance. For example, does your model better predict female speech over male speech? If so, retrain with new datasets to overcome any problem areas.

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

Sean Green

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.

Jamyson Haug

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
