Projection: a mechanism for human-like reasoning in Artificial Intelligence

Posted by in categories: physics, robotics/AI, transportation

(2022). Journal of Experimental & Theoretical Artificial Intelligence. Ahead of Print.

AI has for decades attempted to code commonsense concepts, e.g., in knowledge bases, but struggled to generalise the coded concepts to all the situations a human would naturally generalise them to, and struggled to understand the natural and obvious consequences of what it has been told. This led to brittle systems that did not cope well with situations beyond what their designers envisaged. John McCarthy (1968) said ‘a program has common sense if it automatically deduces for itself a sufficiently wide class of immediate consequences of anything it is told and what it already knows’; that is a problem that has still not been solved. Dreifus (1998) estimated that ‘Common sense is knowing maybe 30 or 50 million things about the world and having them represented so that when something happens, you can make analogies with others’. Minsky presciently noted that common sense would require the capability to make analogical matches between knowledge and events in the world, and furthermore that a special representation of knowledge would be required to facilitate those analogies. We can see the importance of analogies for common sense in the way that basic concepts are borrowed, e.g., the tail of an animal, or the tail of a capital ‘Q’, or the tail-end of a temporally extended event (see also examples of ‘contain’, ‘on’, in Sec. 5.3.1). More than this, for known facts, such as ‘a string can pull but not push an object’, an AI system needs to automatically deduce (by analogy) that a cloth, sheet, or ribbon, can behave analogously to the string. For the fact ‘a stone can break a window’, the system must deduce that any similarly heavy and hard object is likely to break any similarly fragile material. Using the language of Sec. 5.2.1, each of these known facts needs to be treated as a schema,14 and then applied by analogy to new cases.

Projection is a mechanism that can find analogies (see Sec. 5.3.1) and hence could bridge the gap between models of commonsense concepts (i.e., not the entangled knowledge in word embeddings learnt from language corpora) and text or visual or sensorimotor input. To facilitate this, concepts should be represented by hierarchical compositional models, with higher levels describing relations among elements in the lower-level components (for reasons discussed in Sec. 6.1). There needs to be an explicit symbolic handle on these subcomponents; i.e., they cannot be entangled in a complex network. For visual object recognition, a concept can simply be a set of spatial relations among component features, but higher concepts require a complex model involving multiple types of relations, partial physics theories, and causality. Secs. 5.2 and 5.3 give a hint of what these concepts may look like, but a full example requires a further paper.

The big new idea for making self-driving cars that can go anywhere

Posted by in categories: robotics/AI, transportation

The mainstream approach to driverless cars is slow and difficult. These startups think going all-in on AI will get there faster.

Twitter shareholders sue Musk, claim he sought to drive down stock price

Posted by in categories: economics, Elon Musk, engineering, sustainability, transportation

All I can say is that I hope his self indulgence for his favorite ☆HOBBY☆ — Twitter itself — doesn’t sabotage the interplanetary future he’s defined and actually begun to to successfully realize, doing so against all odds in so many fields, cas diverse as science, engineering, economics, politics, and the recent history and the seeming decline in public enthusiasm, funding, and any sort of clear direction. He didn’t just subvert those roadblocks, he OBLITERATED them. SPECTACULARLY.

All that progress and innovation can and WILL be undone in seconds if he makes himself into an allie of a republican party that has abandoned truth, abandoned science, and abandoned every semblance of honor, loyalty, and reason.

A republican party that has abandoned Democracy ITSELF.

The Perseverance Rover of NASA captured a flying object on Mars

Posted by in categories: alien life, robotics/AI, transportation

Is this true?

The Perseverance rover has been on Mars for two weeks and has now spun its wheels and began its maiden trek over the red planet’s surface. According to new images transmitted to Earth by the one-ton robot on Friday, the voyage was a quick one.

Engineers have worked tirelessly to get the vehicle and its numerous equipment up and operating, including instruments and a robotic arm. Perseverance’s mission is to look for indications of alien life in the Jezero crater, which is located near the equator. This will take roughly 15 kilometers throughout the following Martian year (approximately two Earth years).

Lasers reveal ‘lost’ pre-Hispanic civilization deep in the Amazon

Posted by in category: transportation

Millions of lasers shot from a helicopter flying over the Amazon basin have revealed evidence of unknown settlements built by a “lost” pre-Hispanic civilization, resolving a long-standing scientific debate about whether the region could sustain a large population, a new study finds.

The findings indicate the mysterious Casarabe people — who lived in the Llanos de Mojos region of the Amazon basin between A.D. 500 and 1,400 — were much more numerous than previously thought, and that they had developed an extensive civilization that was finely adapted to the unique environment they lived in, according to the study, published online Wednesday (May 25) in the journal Nature (opens in new tab).

South Bay police department unveils new Tesla patrol cars

Posted by in category: transportation

MENLO PARK (KCBS RADIO) – The Menlo Park Police Department has just received a delivery of the first of its electric patrol cars.

For more, stream KCBS Radio now.

Police volunteers in the department will be part of a pilot program to test the Tesla Y’s as patrol vehicles, starting with three, and eventually, the city is hoping to have all its vehicles be electric by 2030.

How Americans think about artificial intelligence

Posted by in categories: employment, food, health, law, robotics/AI, transportation

Artificial intelligence (AI) is spreading through society into some of the most important sectors of people’s lives – from health care and legal services to agriculture and transportation.1 As Americans watch this proliferation, they are worried in some ways and excited in others.

In broad strokes, a larger share of Americans say they are “more concerned than excited” by the increased use of AI in daily life than say the opposite. Nearly half of U.S. adults (45%) say they are equally concerned and excited. Asked to explain in their own words what concerns them most about AI, some of those who are more concerned than excited cite their worries about potential loss of jobs, privacy considerations and the prospect that AI’s ascent might surpass human skills – and others say it will lead to a loss of human connection, be misused or be relied on too much.

But others are “more excited than concerned,” and they mention such things as the societal improvements they hope will emerge, the time savings and efficiencies AI can bring to daily life and the ways in which AI systems might be helpful and safer at work. And people have mixed views on whether three specific AI applications are good or bad for society at large.

Pennsylvania woman being treated for rabies after encountering monkey in aftermath of crash

Posted by in category: transportation

A woman who happened upon the Friday crash of a pickup towing a trailer transporting 100 monkeys is being treated after a monkey spit at her and she developed pink-eye symptoms. #Conjunctivitis …Is Conjunctivitis a symptom of #monkeypox

People for the Ethical Treatment of Animals (PETA) said the U.S. Department of Agriculture is investigating the accident, which occurred on an east-central Pennsylvania highway, and the subsequent attempts to round up some of the cynomolgus macaque monkeys who had escaped from their crates.

The accident involved the collision of the pickup and a dump truck near the Danville exit on Interstate 80. Pennsylvania State Police said several monkeys had escaped following Friday’s collision and one remained unaccounted for overnight.
