The sense of smell is known to be the most difficult, but at the same time a strong sense of perception. It is proved that it is smells that are best printed in memory, and for many years, you cannot even think about them, but when you hear it, just remember. They are also great for identification. Perhaps that is why Russian scientists created the newest neural network, which is able to recognize, read and memorize smells. Moreover, a small device (already patented, by the way) for it to have enough on hand.What does it do? The most obvious option is to recognize the smells of toxic, flammable and elusive gases for humans. This is the conclusion of the system of protection of premises to a new level. It is also useful discovery for science as a whole, for example, to classify new flavors, to find differences between similar substances. In fact, we are talking about a gas analyzer, but it is very precise and expanded in terms of functionality. With it, you can achieve extremely high accuracy in determining the composition of gases, impurities in them, and their danger.
