Meanwhile the deepest misconception here is that machine learning bias will always be bias about *people*. It won’t. It might be bias against Siemens sensors, or Sony cameras, and you might be looking for failures in gas turbines, not cancer or criminals.

There is a ‘panic of the new here’. the fear is not just that it’s biased but that there’s no way to tell, and that this is somehow fundamentally new and different from other tech or organization, where there are (supposedly) clear logical steps that you can audit. I don’t agree.

Hence, it is completely false to say that ‘AI is maths, so it cannot be biased’. But it is equally false to say that ML is ‘inherently biased’. ML finds patterns in data - what patterns depends on the data, and the data is up to us, and what we do with it is up to us

ML has no semantic understanding of what it’s looking at. We look at a grid of pixels and translate that into sheep, or skin, or rulers, but the system just sees a string of numbers. It isn’t seeing 3D space, or objects, or texture. It’s just seeing patterns in data.

This might have consequences for a system that involves people either because your training data reflects human diversity unevenly, or because of some other bias in the data that actually has nothing to do with people.
