Now technology can be a mirror to your thoughts


Researchers have revealed a new technology that remembers important information and forget the less important memories.

The technology is named as “Organismoids” that works the same way as human thought works.

“I learn slowly, but I keep forgetting other things along the way, so there is a graceful degradation in my accuracy of detecting things that are old,” Purdue University’s Edward G. Tiedemann Jr. and distinguished Professor of Electrical and Computer Engineering Kaushik Roy explained to

“What we are trying to do is mimic that behavior of the brain to a certain extent, to create computers that not only learn new information but that also learn what to forget.”

A ceramic “quantum material”, Samarium Nickelate is used to make the organismoid devices. “These devices possess certain characteristics of living beings and enable us to advance new learning algorithms that mimic some aspects of the human brain,” Roy said to “The results have far reaching implications for the fields of quantum materials as well as brain-inspired computing.”

The samarium nickelate undergoes a massive change in resistance when exposed to hydrogen gas, as hydrogen atoms “dope” its crystal lattice. The material essentially “breathes,” expanding and contracting as hydrogen is added and removed. This resistance change is a quantum mechanical effect that is highly unusual, and its gradual conductance decay is similar to habituation behavior in animals. For this reason, the researchers describe the way that these materials behave as “organismic” and analogous to the ebb and flow of memory and information retention in living brains.

“This could be really important because it’s one of the first examples of using quantum materials directly for solving a major problem in neural learning,” Ramanathan said. The result is their “neural learning model,” adaptive synaptic plasticity, which they use the organismoids to implement.

Using these tools, the researchers are modeling actual problems in neuromorphic computing such as catastrophic forgetting. Eventual applications may be seen in AIs capable of improved facial recognition, complex decision-making, and reasoning.

Organismoids could also be applied in the nascent field of spintronics, which replaces the binary system of ones and zeros of traditional systems with the “spin state” of electrons. Eventually, using these technologies, researchers might be able to create circuits that mimic the human brain, with a far more compact design and components that resemble synapses and neurons, with just one spintronic device.
