Deep Learning

Esta tecnología -creada aparentemente por la misma gente de Facebook- presume ser el siguiente paso en inteligencia artificial, capaz de estudiar a un usuario no solo a nivel gustos y follows, sino como si fuera otro cerebro: por sus emociones y personalidad, habitos y conductas, ocultas en cada texto, foto, clic, y demás acciones que ejecuta por esta red…

Facebook is set to get an even better understanding of the 700 million people who use the social network to share details of their personal lives each day.

A new research group within the company is working on an emerging and powerful approach to artificial intelligence known as deep learning, which uses simulated networks of brain cells to process data. Applying this method to data shared on Facebook could allow for novel features and perhaps boost the company’s ad targeting.

Deep learning has shown potential as the basis for software that could work out the emotions or events described in text even if they aren’t explicitly referenced, recognize objects in photos, and make sophisticated predictions about people’s likely future behavior.

The eight-person group, known internally as the AI team, only recently started work, and details of its experiments are still secret. But Facebook’s chief technology officer, Mike Schroepfer, will say that one obvious way to use deep learning is to improve the news feed, the personalized list of recent updates he calls Facebook’s “killer app”…

What is a face?

How Does Our Brain Know What Is a Face and What’s Not?

Objects that resemble faces are everywhere. Whether it’s New Hampshire’s erstwhile granite “Old Man of the Mountain,” or Jesus’ face on a tortilla, our brains are adept at locating images that look like faces. However, the normal human brain is almost never fooled into thinking such objects actually are human faces.

A new study from Sinha and his colleagues reveals the brain activity that underlies our ability to make that distinction. On the left side of the brain, the fusiform gyrus – an area long associated with face recognition – carefully calculates how “facelike” an image is. The right fusiform gyrus then appears to use that information to make a quick, categorical decision of whether the object is, indeed, a face…
