As HN: What efforts are currently being made to overcome racial biases in AI?

I've read a lot about racially biassed AIs recently. Eg the depixelizer that turns Obama white:

Face detection also works better on white faces.

What work is currently being done to overcome this, if any?

Is this a problem with dataset availability? And if so are there any ongoing efforts to create more diverse datasets?

Would creating a way to crowd source datasets work / be useful to anyone - eg if you could submit images/speech/video of yourself and label them?

Thanks
