IBM scientists imitate the functionality of neurons with a phase-change device
Quote:IBM scientists have created randomly spiking neurons using phase-change materials to store and process data. This demonstration marks a significant step forward in the development of energy-efficient, ultra-dense integrated neuromorphic technologies for applications in cognitive computing.

Inspired by the way the biological brain functions, scientists have theorized for decades that it should be possible to imitate the versatile computational capabilities of large populations of neurons. However, doing so at densities and with a power budget that would be comparable to those seen in biology has been a significant challenge, until now.

"We have been researching phase-change materials for memory applications for over a decade, and our progress in the past 24 months has been remarkable," said IBM Fellow Evangelos Eleftheriou. "In this period, we have discovered and published new memory techniques, including projected memory, stored 3 bits per cell in phase-change memory for the first time, and now are demonstrating the powerful capabilities of phase-change-based artificial neurons, which can perform various computational primitives such as data-correlation detection and unsupervised learning at high speeds using very little energy."

The artificial neurons designed by IBM scientists in Zurich consist of phase-change materials, including germanium antimony telluride, which exhibit two stable states, an amorphous one (without a clearly defined structure) and a crystalline one (with structure). These materials are the basis of re-writable Blu-ray discs. However, the artificial neurons do not store digital information; they are analog, just like the synapses and neurons in our biological brain.

I just want to be the first to welcome our new AI overlords.

Ha! Those two responses are exactly what I opened this thread to say: "I welcome Lord Skynet, our new AI overlord."

I wonder if these could one day be applied to the human brain o _o

I'd vote for Skynet over any of the humans running for office.

RE: IBM scientists imitate the functionality of neurons with a phase-change device
Although a step forward this is only one part of what needs to be done to emulate the brain. The main difference is that the brain has far greater connectivity than can be achieved using conventional computjng. This is why graphics cards have been so useful for deep learning, they are designed to perform many tasks in parallel.

Secondly, neural architectures aren't particularly easy to understand. Either in how to design them or how they are adapting.

The Clay Institute Millennium Prize Problems are not wired to the collective intellect of the humankind. Sadly, such a shame! I mean, what evil envy, aborts and terrorism do destroy the global intellect. We must not build the artificial intellect in PC, we shall better to support evaluation of the human ability to think. Any individual is like the super-computer, more powerful and more beautifully designed, than the entire Universe. So, connecting the human abilities into the social media, one makes the super-super-super powerful intellect. The global intellect, which is capable to solve such hardly solvable Millennium Prize problems. The optimal web of interconnected human intellects, is it achievable?
