AI can now tell if you're a man or a woman, just by your smile

Men and women have different patterns of smiling, new research reports -- and this, the authors add, can allow AI to easily distinguish between the genders. Image credits Benjamin D.

Regardless, while romance unfolds across the world, one team of researchers from the University of Bradford is working to bring this subtle yet powerful gesture to bear in our interactions with artificial intelligence (AI). According to them, computers can learn to differentiate between men or women simply by observing a smile. Led by Professor Hassan Ugail, the team mapped 49 distinct points (or'landmarks) on smiling human faces -- mainly around the eyes, mouth, and down the nose.
