Google's AI 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. A graph neural network model was trained to learn numerous examples of particular molecules paired with the smell labels that they arouse, e.g., “beefy”, “floral”, or “minty”. The scientists tried to find out if the model has learned to predict the odours of new molecules that humans have never smelled and also that differed from molecules used to train the GNN model. Using this finding to tackle global health problem The map of odour closely connected to perception and biology across the animal kingdom opens the scope of many advancements in medical sciences.
