How Self-Driving Cars Can Figure Out Parking
Posted by Dan Kummer in categories: mapping, robotics/AI, transportation
Robocars need to park sometimes, and find places to drop off and pick up passengers. The vast array of rules for public and private parking and pick-up spaces is more complex than the rules of the road, so a public and private mapping system is called for.

The Urge to Radical Life Extension

To the scientists here, could humans live for 300 years?
Those portions of the modern longevity community interested in bringing an end to aging and extending healthy human life span indefinitely tend to be the older portions, people who have been a part of the broader movement for quite some time. Newcomers tend to be more moderate, aiming at lesser goals. Perhaps this is a result of the successful projects, such as the SENS Research Foundation and Methuselah Foundation, tending to moderate their rhetoric as they attract a broader and larger base of support. I think that this road to moderation might be a problem, and that there is thus a continued role for those who loudly declaim that the goal is to control aging absolutely, via new medical technology, and that the natural consequence of that control is healthy, active, youthful life that extends for centuries or more.

How quantum brain biology can rescue conscious free will
Posted by Richard Christophr Saragoza in categories: biological, computing, information science, neuroscience, quantum physics
Conscious “free will” is problematic because brain mechanisms causing consciousness are unknown, measurable brain activity correlating with conscious perception apparently occurs too late for real-time conscious response, consciousness thus being considered “epiphenomenal illusion,” and determinism, i.e., our actions and the world around us seem algorithmic and inevitable. The Penrose–Hameroff theory of “orchestrated objective reduction (Orch OR)” identifies discrete conscious moments with quantum computations in microtubules inside brain neurons, e.g., 40/s in concert with gamma synchrony EEG. Microtubules organize neuronal interiors and regulate synapses. In Orch OR, microtubule quantum computations occur in integration phases in dendrites and cell bodies of integrate-and-fire brain neurons connected and synchronized by gap junctions, allowing entanglement of microtubules among many neurons. Quantum computations in entangled microtubules terminate by Penrose “objective reduction (OR),” a proposal for quantum state reduction and conscious moments linked to fundamental spacetime geometry. Each OR reduction selects microtubule states which can trigger axonal firings, and control behavior. The quantum computations are “orchestrated” by synaptic inputs and memory (thus “Orch OR”). If correct, Orch OR can account for conscious causal agency, resolving problem 1. Regarding problem 2, Orch OR can cause temporal non-locality, sending quantum information backward in classical time, enabling conscious control of behavior. Three lines of evidence for brain backward time effects are presented. Regarding problem 3, Penrose OR (and Orch OR) invokes non-computable influences from information embedded in spacetime geometry, potentially avoiding algorithmic determinism. In summary, Orch OR can account for real-time conscious causal agency, avoiding the need for consciousness to be seen as epiphenomenal illusion. Orch OR can rescue conscious free will.
Keywords: microtubules, free will, consciousness, Penrose-Hameroff Orch OR, volition, quantum computing, gap junctions, gamma synchrony.
We have the sense of conscious control of our voluntary behaviors, of free will, of our mental processes exerting causal actions in the physical world. But such control is difficult to scientifically explain for three reasons:

Royal Navy to develop autonomous AI mine-hunter
Posted by Dan Kummer in category: robotics/AI
One of the Navy’s first AI projects, the autonomous submersible, will be delivered by BAE Systems and Envitia
The Royal Navy’s Route Survey and Tasking Analysis (RSTA) project aims to deliver an automated capability for detecting and rendering harmless underwater mines in UK waters by 2022. Currently, a fleet of mine-hunter ships use sonar to detect anomalies on the seabed, but the AI-enabled submersibles to be developed by BAE Systems Applied Intelligence and British geospatial data company Envitia are expected to work in a fleet to scan objects, identify threats and make decisions about what action to take much faster.

Neuromorphic Hardware: Trying to Put Brain Into Chips
Posted by Paul Battista in categories: computing, neuroscience
Hi all.
Up until now, chip-makers have been piggybacking on the renowned Moore’s Law for delivering successive generations of chips that have more compute capabilities and are less power hungry. Now, these advancements are slowly coming to a halt. Researchers around the world are proposing alternative architectures to continue producing systems which are faster and more energy efficient. This article discusses those alternatives and reasons why one of them might have an edge over others in averting the chip design industry from getting stymied.
Moore’s law, or to put it differently — savior of chip-makers worldwide — was coined by Dr. Gordon Moore, the founder of Intel Corp, in 1965. The law states that the number of transistors on a chip would double every 2 years. But why the savior of chip-makers? This law was so powerful during the semiconductor boom that “people would auto-buy the next latest and greatest computer chip, with full confidence that it would be better than what they’ve got”, said former Intel engineer Robert P. Colwell. Back in the day writing a program with bad performance was not an issue as the programmer knew that Moore’s law would ultimately save him.
