sexual. When the system was evaluated in a group of 1,000 individuals, of which only 7% belonged to homosexual people (for more representativeness is the actual percentage of the population), the results were not the best. In the best case a sample of 10 individuals were recognized with 90% accuracy.
There is also a real possibility of bias in the system due to the data: first, they included only young white Americans of the type of man/woman and homosexual/normal.
"Despite our attempts to obtain a more diverse sample, we were limited to the study of white participants from the United States. Because of prejudice against homosexuals and the use of online Dating sites are unevenly distributed among different ethnic groups, we were unable to find a sufficient number of non-white homosexual members."
Although scientists suggest that other ethnic groups are likely to have similar facial patterns and the system will also be effective to define, in fact it is necessary to confirm and not to assume.
You can Also argue that the classifier is collected, the characteristic features of people on Dating sites, not without the help of the mechanism of self-selection, for example, American men with a normal sexual orientation can deliberately avoided appearance, which would show that they can be homosexual.
Of Course, the real effectiveness of this system reasonably questioned, since it is trained based on the limited amount of data and mostly effective examples from this pool. Further research will be necessary. However, it seems short-sighted to assume that the running system is impossible.the
Many argue that this technology is no better than "phrenology 2.0", shell when unrelated physical traits with complex internal processes, and that is understandable, but not true.
"Physiognomy is now widely and rightly rejected as a combination of superstition and racism disguised as science," the scientists write in the introduction to the work (physiognomy judging by the facial features, while the phrenologists studied the shape of the skull). But this pseudo science has failed because its supporters were moving in the opposite direction. They decided who was involved in "criminal cases" or "sexual deviations", and then determine what features are common to such people.
It Turned out that people just don't cope well with such tasks, we see people too much of myself and make instinctive conclusions. But this does not mean that the visible features and the physiology or psychology are not related. No one doubts that the machine can mark in people the traits that they do not see, from the tiny chemical traces of explosive shells and drugs to the subtle patterns on the MRI scans, which tell of a beginning cancer.
From the article it follows that the computer vision system chooses the same subtle patterns, both artificial and natural, but in the first place; the scientists tried to focus on traits that cannot be changed easily. This supports the hypothesis that sexuality is biologically determined, perhaps under the influence of various factors on the development of the fetus, which can result in small physiological differences and hormonal patterns of the appeal. The observed system patterns are similar to those predicted by the theory of prenatal hormones.
This is the starting point of a broader social and philosophical debates about love, sexuality, determinism and intelligence emotions and personalities to simple biological characteristics. But we won't. Better touch on other serious issues regarding confidentiality.the
The effects of the automatic determination of the orientation of the man on several photos of the huge, first of all and most importantly, because put people of the LGBTQ groups at risk throughout the world in those places, where they remain oppressed minority. The potential abuse of such a system is huge and some may rightfully disagree with the decision of the researchers about its creation and documentation.
But similarly you could argue that it is better to be able to open it, to implement countermeasures or otherwise to a
