Google's artificial intelligence model can predict odour like human beings

Google has built an artificial intelligence model with human like capability of predicting odour. The map developed by the team of Google AI links molecule structure to the aroma of substance and can even predict smell that is still unnoticeable by humans. Smells are sensed when molecules riding on the air stick to the sensory receptors present in the nose. However, it is more difficult to predict smell than colour. Because, unlike the human eye, which has only three sensory receptors for sensing the photons of red, green and blue colour, our nose has over 300 receptors.
