A New Algorithm Trains AI to Erase its Biases
It's like sensitivity training for algorithms.
In recent years, artificial intelligence has struggled with a major PR problem: whether or not it’s intentional, developers keep programming biases into their systems, creating algorithms that reflect the same prejudiced perspectives common in society.
That’s why it’s intriguing that engineers from MIT and Harvard University say they’ve developed an algorithm that can scrub the bias from AI — like sensitivity training for algorithms.

The tool audits algorithms for biases and helps re-train them to behave more equitably, according to new research presented this week at the Conference on Artificial Intelligence, Ethics and Society.
And even then, once complex AI systems deploy in the real world, it becomes very difficult to evaluate how exactly they’re making their decisions. That’s why automating the process is so important — the new tool can go in and reconfigure how much value the AI system gives to each aspect of its training data, according to the research.
For instance, if an algorithm was trained to determine that black people would be poor candidates for a job, the new tool would feasibly be able to teach the algorithm to evaluate candidates on the relevant factors of their applications instead.
Of course, it’s possible the new algorithm could have biases of its own. But given that artificial intelligence systems are already out in the field actively recommending that cops over-police areas with more racial minorities, it’s urgently important that researchers tackle algorithmic bias.
“Facial classification in particular is a technology that’s often seen as ‘solved,’ even as it’s become clear that the datasets being used often aren’t properly vetted,” Alexander Amini, an MIT AI researcher who helped develop the new tool, told TechXplore. “Rectifying these issues is especially important as we start to see these kinds of algorithms being used in security, law enforcement and other domains.”
