The news: Facebook revealed a self-supervised artificial intelligence model it claims can accurately learn to categorize Instagram images with less human assistance than before.
Here’s how it works: Researchers at Facebook fed the AI, called SEER, over 1 billion unlabeled images extracted from public IG accounts. Using self-supervised learning—a method where a machine learns to train itself without human data labeling—SEER achieved a classification accuracy score of 84.2%, outperforming “the most advanced, state-of-the-art self-supervised systems,” per Facebook.
What’s next?: While SEER is still in its early stages, Facebook believes it can bring about real-world benefits. Here are some of SEER’s possible use cases:
The bigger picture: Ever-increasing data sharing by users will likely lead to rapid AI advancement.
Self-supervised programs are data-intensive and reportedly require around 100x more images to achieve comparable levels of accuracy than AI’s trained using human-generated labels. Luckily for Facebook and others interested in building AI, there’s no shortage of data. A 2020 IDC report predicts the amount of data created globally in the next three years will exceed the amount created in the past three decades.
At the same time, Cisco expects the total number of users on the internet to increase from 3.9 billion in 2018 to around 5.3 billion in 2023. All this means future AI programs will benefit from both new users from which to harvest content, and the willingness of those users to upload more photos, texts, videos, and voice recordings than ever before.
Why this could backfire: Facebook’s technical advances in AI still leaves lingering foundational questions around algorithmic bias unaddressed.
Facebook’s choice to train its algorithm on Instagram images could bias the AI toward younger demographics with greater access to social media and mobile apps, with no guarantee of accuracy for groups underrepresented in that data set, according to Nikita Aggarwal, a research associate at the Oxford Internet Institute. “There’s a difference between developing AI systems that can identify correlations in data to classify images,” Aggarwal told New Scientist, “and systems that can actually understand the meaning and context of what they’re doing or indeed reason about it.”
While Facebook claims self-supervised AI models removal of human-generated labels could “mitigate some of the biases” inherent in data curation, that wouldn’t necessarily address biases baked into the society—and therefore the data—itself. Even if self-supervised AI programs overcome accuracy issues, they still risk replicating the same cultural and social biases endemic to the type of prejudiced data it's trained on—garbage in, garbage out—resulting in AI recapitulating the same prejudices from the data it’s fed.
