Are algorithms objective? No, that’s an illusion. Robots can be controlled through computer programs in the form of algorithms, which are the basis for artificial intelligence (AI). Algorithms define how a particular task is to be performed.

How do you mitigate bias in AI?

To detect AI bias and mitigate against it, all methods require a class label (e.g., race, sexual orientation). Against this class label, a range of metrics can be run (e.g., disparate impact and equal opportunity difference) that quantify the model’s bias toward particular members of the class.

To summarize: algorithms are automated instructions and can be simple or complex, depending on how many layers deep the initial algorithm goes. Machine learning and artificial intelligence are both sets of algorithms, but differ depending on whether the data they receive is structured or unstructured.

How can machine learning reduce bias?

Identify potential sources of bias.
Set guidelines and rules for eliminating bias and procedures.
Identify accurate representative data.
