Samsung Engineers Propose 'Copying and Pasting' the Brain onto AI Chips (engadget.com) 134

Posted by EditorDavid from the brain-dumps dept.
Samsung has proposed a way to build brain-like computer chips by "copying and pasting" a brain's neuron wiring map onto 3D neuromorphic chips. Engadget reports: The approach would rely on a nanoelectrode array that enters a large volumes of neurons to record both where the neurons connect and the strength of those connections. You could copy that data and 'paste' it to a 3D network of solid-state memory, whether it's off-the-shelf flash storage or cutting-edge memory like resistive RAM. Each memory unit would have a conductance that reflects the strength of each neuron connection in the map. The result would be an effective return to "reverse engineering the brain" like scientists originally wanted, Samsung said.

The move could serve as a 'shortcut' to artificial intelligence systems that behave like real brains, including the flexibility to learn new concepts and adapt to changing conditions. You might even see fully autonomous machines with true cognition, according to the researchers.
"Envisioned by the leading engineers and scholars from Samsung and Harvard University, the insight was published as a Perspective paper, titled 'Neuromorphic electronics based on copying and pasting the brain'..." Samsung said in a statement.

In short, they're proposing a method that "directly downloads the brain's neuronal connection map onto the memory chip."
