> Gebru, a widely respected leader in AI ethics research, is known for coauthoring a groundbreaking paper that showed facial recognition to be less accurate at identifying women and people of color, which means its use can end up discriminating against them.
Surely this is a function of location? I understand the U.S.-English term “person o color” to be convoluted language for “not white”. One simple thing I notice is that if I search for, say, “child” on Google Image Search, the images indeed tend to look as what one would expect from the average inhabitant of an English-speaking nation, when I search “子供”, I indeed mostly see what I would expect from Japan. Similarly, if I search for “house”, what I find tends to look like a house most likely situated in the Netherlands; with “บ้าน”, it does resemble more so stereotypical Thai architecture.
I would assume that a.i.'s made in, say, Japan would yield different results.
- xmprt 5y agoThe problem is that AI (and the English language to some extent) transcends borders. So even if it's an AI developed in the US, it can potentially impact people outside the US and it makes ethical sense to build something that doesn't exclude groups based on arbitrary conditions.
- Blikkentrekker 5y agoYes, but to offset that, many a.i. in English were also made outside of English-speaking regions, in what one assumes to be proportional degree. This is probably why there is more variance when searching for English terms as wel, as a Lingua Franca. If I search “house” I do see some styles of architecture not commonly found in Anglo-Saxon nations, whereas all occurrences of “huis” do seem to be situated in the Netherlands.
- sangnoir 5y ago> many a.i. in English were also made outside of English-speaking regions Different regions, yes - but where did the training and benchmark datasets come from? AI research is surprisingly monocultural (or use "standardized benchmarks" if you're feeling charitable). Not too long ago, there was a paper posted on HN that showed that a bunch of the datasets contain mislabeled data, which means a lot of "different" models are encoding similar biases.
- mschuster91 5y agoSearching for "child" or "house" will yield what has been classified as such in training - and searching for Japanese or Thai labels will do the same. No surprise there, if the labels don't get normalized before training. And normally, that's harmless - as you said, you'd expect to see an AI finding pictures of houses in the region/culture you are searching it. But in a multi-cultural/multi-ethnic society, searching for "people" and showing up only what is considered the "majority" has a whole different lot of ethical implications. Identifying and ideally remediating such issues is why ethics research is so sorely needed.
- b9a2cab5 5y agoNo, remediating such issues (only predicting the maximum likelihood class in the dataset) is a problem of _machine learning and optimization_ research, not ethics research. There is nothing an ethicist can do to solve this problem. It is easy to point out problems with existing AI and write a bunch of papers to get yourself tenure. It is very hard to fundamentally advance our understanding of deep learning models past a fancy maximum likelihood estimation problem.
- mschuster91 5y ago> _machine learning and optimization_ research Ethics education is (unfortunately) not really seen as necessary across the tech field, which is why ethics researchers need to be part of at all stages of AI development. And for what it's worth, ethics researchers should be part of all technology development - the "racist soap dispenser" should have been more than enough proof of how even a very simple, innocent product can contribute to ethnic discrimination.
- Blikkentrekker 5y ago> And normally, that's harmless - as you said, you'd expect to see an AI finding pictures of houses in the region/culture you are searching it. I am not actually; I am searching for “huis”, not “Nederlands huis”; I'd expect the result I obtain from the former with the latter. I'd actually expect “house” and “huis” to reveal similar results from a good search engine. Obviously this is not easily possible with how it is trained with corpora in a specific language, but from usability I think this is undesirable, if I specifically want Dutch houses I can always add that term as a specification; there is no way to simply search for houses, wherever they might be, in Dutch, or English, or Thai, or any other language. That is to say, I'm not arguing that there is no problem; I'm arguing that the problem is highly dependent upon location, and that he article should not take such a U.S.A.-centric stance and act as though the reset of the world not exist.
- baxter001 5y agoCompletely not the focus of the article, and you've turned the result of an error rate of 0.8 percent for gender classification of light-skinned men and a 34.7 percent error rate for the same classifier on dark-skinned women - into some kind of google image search language game? I can only quote Joy Buolamwini on this: “To fail on one in three, in a commercial system, on something that’s been reduced to a binary classification task, you have to ask, would that have been permitted if those failure rates were in a different subgroup?”
- b9a2cab5 5y agoThe answer would probably be yes if that subgroup wasn't a large percentage of the dataset used for training and testing. Or if that subgroup wasn't a large percentage of the user base. Come on, if you've worked at any large company using ML you know model performance is literally just taking the average accuracy/ROC/precision/etc over your training dataset plus some hold out sets. Then you track proxy metrics like engagement to see if your model actually works in production. At no point does race come into the equation. Naturally, if your choice of subgroup happens to not be a large proportion of either the dataset or the userbase then you don't see the poor performance on that subgroup show up in your metrics so you don't care to fix it.
- indigo945 5y agoObviously, but the question is, why were there no Black women in the data set, and what care can be taken to prevent racialized bias when selecting the data set in the future?
- b9a2cab5 5y agoCertainly you can ask these questions but these are business process issues, not technical ones. They're unrelated to AI. My personal take is you won't see any tangible movement on this until black women (or whatever group you choose) comprise a tangible proportion of revenue generating users. Corporations operate for money and nothing else.
- b9a2cab5 5y agoThe meaning in woke terminology is more subtle than just "not white". For example Asians would likely be excluded in this case, and Middle Easterners and other minorities. "People of color" in this case means blacks and dark skinned Latinos. The idea that AI itself can be biased (as opposed to the dataset) also has some significant problems. The lead of Facebook AI Research got canceled on Twitter because he pointed out that it's the bias in the dataset used to train the AI that results in bias in the AI and not the AI itself that's biased. I'd also question whether Gebru is a "widely respected leader in AI ethics research". Model interpretability is not even close to a solved problem so just because you can demonstrate some correlation between images of black people and worse performance does not imply that "black person" is a causative factor. It could literally be dataset distribution or image contrast or any number of other plausible explanations that are easily fixable by an ML engineer.
- tsimionescu 5y agoThe AI is the final product of applying a learning algorithm on a training set. Claiming that "the AI is not biased, the training set is" is like saying "this running program isn't buggy, it's just the source code that is buggy".
