Artificial Intelligence Being Taught to Recognize Smells

A scientist at Cornell University working with a researcher at Intel has just created an AI algorithm trained to recognize 10 scents by mimicking the mammalian olfactory bulb (MOB). Give the algorithm a computer chip to run on and it can learn to identify new odors.

Can artificial intelligence be used to predict what a molecule will smell like based on its structure?

"We now can use artificial intelligence to predict how any chemical is going to smell to humans. ... The machine learning algorithm can eventually predict how a new chemical will smell even though we may initially not know if it smells like a lemon or a rose."

Can humans tell artificial smells from real ones?

Based on the research material, I learned that we have an olfactory system in the upper part of our nose to indentify odors. My hypothesis was that most of the people tested would correctly identify the natural scents. My hypothesis was proven correct. People really can distinguish artificial and natural odors.

Can a machine detect smell?

The expression "electronic sensing" refers to the capability of reproducing human senses using sensor arrays and pattern recognition systems. Since 1982, research has been conducted to develop technologies, commonly referred to as electronic noses, that could detect and recognize odors and flavors.

What does the ability to detect smell rely on?

Detecting a taste (gustation) is fairly similar to detecting an odor (olfaction), given that both taste and smell rely on chemical receptors being stimulated by certain molecules. The primary organ of taste is the taste bud.

Can a computer smell?

Answer: A computer chip that can smell hazardous chemicals in the air. ... While Loihi could potentially learn 10 different odors, the system has trouble differentiating odors that are similar but come from different sources (like different fruits that have similar smells, for example).

How many smells can humans smell?

The Human Nose Can Detect More Than 1 Trillion Scents. New research reveals that the human sense of smell is much more powerful than scientists thought. Humans have powerful sight and hearing. We are able to pick out several million distinct colors and almost half a million separate tones.

How many ppm can humans smell?

The Odor Threshold for ammonia has been documented in different studies as low as . 04 ppm and as high as 57 ppm. The American Association of Railroads says most people can smell ammonia between 0.04 to 20 ppm. OSHA says the Odor Threshold is between 5 and 50 ppm.

Why can humans distinguish so many smells?

These are only three of the roughly 1 trillion scents that the human nose and brain are capable of distinguishing from each other, according to a new study. ... Humans detect smells by inhaling air that contains odor molecules, which then bind to receptors inside the nose, relaying messages to the brain.

Can humans track scents?

The scientists found that humans act much like dogs do while tracking a scent, sniffing repeatedly to trace the smell's source. They didn't do so well with one blocked nostril, suggesting that the stereo effect of two nostrils helps people to locate odours in space.

Can Smell be transmitted electronically?

Digital smell technology is the main application of e-nose. With digital scent technology, it is possible to sense, transmit & receive smell through the internet.

Can your phone smell?

Once deployed, the phone will be able to detect aromas far more precisely than human noses. ... That's mostly because human noses are fine — to varying degrees, changing from person to person — at detecting smells, but the nose can quickly become accustomed to the smell.
