One of Facebook's latest AI projects, unveiled at its F8 developer conference on Wednesday, is to improve a computer's ability to recognize objects in photos.
According to Mike Schroepfer, Facebook's chief technology officer, one of the biggest challenges in improving computers' accuracy in recognizing objects in photos is that there aren't enough correctly labeled photos to train the computer.
As a simple example, before a computer can understand that an apple in a photo is an apple, it needs to be trained with photos of apples, and in these photos, people need to label the fruit.
Given that Facebook owns the Instagram photo-sharing service, in other words, Facebook could use Instagram photos to improve the image recognition capabilities of its AI algorithms. In this regard, Skoropf said that Facebook obtained 3.5 billion Instagram photos, some of which were tagged with user information.
The training for this AI project lasted 22 days and used 330 graphics cards. Manohar Paluri, head of Facebook's applied computer vision division, said the improved image recognition capabilities would allow Facebook to create more accurate audio descriptions of photos for users with visual impairments.
And Skoropf said the new AI image-recognition improvements have been integrated into a variety of Facebook products. In addition, in this series of releases, there is also a relatively "terrifying" technology release-remembering the world with AI.
According to Facebook, using machine learning technology, AI can capture common points from multiple photos taken in the same place and then obtain common points from different perspectives, and use the sense of distance generated in space to construct the environment around the photo. In this way, it may be possible to restore the appearance of the hometown as a child.
Of course, this technology is not limited to the user's own memories. If there are enough photos, some famous landmarks can also be constructed. In this respect, this is a bit similar to Microsoft's Photosynth in the early years, except that Photosynth will try its best to provide superimposed photos, while Facebook is directly showing Point cloud here.
If you guessed correctly, this feature of Facebook should be prepared for Oculus. After all, experiencing such a world through VR will be more immersive than through the screen. Unfortunately, this technology is only a concept product for the time being, but its purpose is to hope that "in the future, people can use such a system to 'relive their old dreams', return to places that have special meaning to themselves, and see people who have special meaning to themselves again.
