Robo-Doc will see you? Maybe, but not just now. This item popped up from the usual suspect tabloid paper sites while searching on AI and memristors. I have tracked down a couple of more reputable sources so, here goes from China Daily (which is also on the spot): >>A robot has passed the written test of China’s national medical licensing examination, an essential entrance exam for doctors, making it the first robot in the world to pass such an exam. Its developer iFlytek Co Ltd, a leading Chinese artificial intelligence company, said on Thursday that the robot scored 456 points, 96 points higher than the required marks. The artificial-intelligence-enabled robot can automatically capture and analyze patient information and make initial Read More ›

Memristors [= memory + resistors] are a promising memory-based information storage technology that can work as non-volatile memory and in neural networks.  They were suggested c. 1971 by Leon Chua, and since HP created a TiO2-based multilayer architecture device exhibiting memristor capabilites in 2007, they have been a focus for research, given their potential. Here, we may ponder a crossbar array of memristor elements forming a signal-processing matrix: Memristors are of interest to AI as a means to effect neural networks. For instance, a crossbar network (as is illustrated just above) has been used to demonstrate powerful image processing. As Sheridan et al reported in Nature, May 22, 2017 (details pay-walled, of course . . . ): >>Sparse representation of Read More ›

as in “your last question, the question for which you will be remembered.” Some interesting answers (in the form of questions) emerge: Can we program a computer to find a 10,000-bit string that encodes more actionable wisdom than any human has ever expressed? – Scott Aronson Are complex biological neural systems fundamentally unpredictable? – Anthony Aguirre Are the simplest bits of information in the brain stored at the level of the neuron? – Dorsa Amir and many more. Everyone seems to be trying their hand on the 20th anniversary. See also: CSICOP’s ridiculously out-of-date questions and answers on evolution show how far naturalism has fallen They don’t even keep up.

As was recently discussed, contrary to objections being made, the concept of blind search and linked search challenge in a configuration or state space is a reasonable and even recognised concept. As we explore this concept a little more, an illustration may be helpful: With this in mind, we may again look at Dembski’s arrow and target illustration from NFL, p. 11: Now, let us ponder again Wiki on state space search: >>State space search is a process used in the field of computer science, including artificial intelligence (AI), in which successive configurations or states of an instance are considered, with the intention of finding a goal state with a desired property. Problems are often modelled as a state space, Read More ›

Sometimes a comment is too good to leave there in the combox. So: LM, 2 in the AI intelligent agency thread: >>It brought to mind the evolution of AI. It all began with lightning (electrons) striking rocks (silicon) for billions of years (might a nearby warm pond be helpful?) until now we have the delicate motions of electrons thru silicon that we know of as computers. The software is the result of random noise in the bits and bytes of the operating system (we’re still working out how that originated. Any day now!) that were duplicated as a separate file and eventually, driven by natural selection, resulting in the wonderful programs we enjoy today. At the furious rate of evolution Read More ›

In his well-known work, No Free Lunch, p. 11, ID Researcher William A Dembski has illustrated the search challenge concept in terms of an arrow hitting a target amidst a reference class of possibilities. In so doing, he reaches back to the statistical mechanical and mathematical concept of a phase space “cut down” to address configurations only (leaving out momentum), aka state space.  He then goes on to speak in terms of probabilities, observing: >>. . . in determining whether an event is sufficiently improbable or complex to implicate design, the relevant probability is not that of the event [= E] itself. In the archery example, that probability corresponds to the size of the arrowhead point in relation to the Read More ›

This is a theme of increasing significance for the ID debate, but also it has overtones for an era where AI technologies may be driving the next economic long wave. Which is of instant, global importance, hence the Perez idealised Long wave illustration: However, this is not about economics (save, as a context for major trends) but about AI, Intelligent Agents as conceived under AI and the intersection with ID. Intelligent Design. Where, it is important to recognise that the concept of intelligence and of agency we will increasingly encounter will be shaped by the dogmas of what is often termed, Strong AI. Techopedia summarises: >>Strong artificial intelligence (strong AI) is an artificial intelligence construct that has mental capabilities and Read More ›

From Sal Cordova at Creation-Evolution Headlines: Chris Rupe co-authored the book Contested Bones with John Sanford to tell about the inadequate evidence for human evolution. The book is almost entirely about bones and the fossil record, but there are 3 pages in that book that refute claims by evolutionary biologists that the human genome is badly designed because of repetitive DNA elements known as Alus. Some 10-11% of the human genome is composed of repeats of specific 300-base pattern called an Alu. Evolutionists claim this is bad design. Their reasoning goes something like this: ‘You only need one copy of a phone book in a house, maybe a few at most, certainly not millions of copies. Therefore the 1 million Read More ›

The Voynich manuscript has long been a mysterious object, seemingly a medicinal or magical survey of plants, or someone’s play on such documents, but written in an unknown alphabetic script: AI is now being brought to bear on the matter.  According to phys dot org: >>U of A computing science professor Greg Kondrak, an expert in natural language processing, and graduate student Bradley Hauer used artificial intelligence to decode the ambiguities in human language using the Voynich manuscript as a case study. Their first step was to address the language of origin, which is enciphered on hundreds of delicate vellum pages with accompanying illustrations. Kondrak and Hauer used samples of 400 different languages from the “Universal Declaration of Human Rights” Read More ›

For some time now, objector DiEb has been raising the question, what do we mean by speaking of “search” in the context of evolutionary search. At 311 in the parody thread, she [IIRC] remarks: >>Search is a central term in the work of Dr. Dr. William Dembski jr, Dr. Winston Ewert, and Dr. Robert Marks II (DEM): it appears in the title of a couple of papers written by at least two of the authors, and it is mentioned hundreds of times in their textbook “Introduction to Evolutionary Informatics“. Strangely – and in difference from the other central term information, it is not defined in this textbook, and neither is search problem or search algorithm. Luckily, dozens of examples of Read More ›

AI — artificial intelligence — is emerging as a future-driver. For example, we have been hearing of driver-less cars, and now we have helmsman-less barges: As The Guardian reports: >>The world’s first fully electric, emission-free and potentially crewless container barges are to operate from the ports of Antwerp, Amsterdam, and Rotterdam from this summer. The vessels, designed to fit beneath bridges as they transport their goods around the inland waterways of Belgium and the Netherlands, are expected to vastly reduce the use of diesel-powered trucks for moving freight. Dubbed the “Tesla of the canals”, their electric motors will be driven by 20-foot batteries, charged on shore by the carbon-free energy provider Eneco. The barges are designed to operate without any Read More ›

The Meltdown-Spectre processor architectural flaw crisis we have been monitoring has deepened as Intel has to patch its initial patch: . . . and as a first wave of the inevitable lawsuits hits. Here, we clip one in San Francisco:   NB: Comment 3 below links and clips documentation AMD has been sued over its response to Spectre. Where also, The Register further reports that there are problems with embedded systems using microprocessors and microcontrollers: >>Patches for the Meltdown vulnerability are causing stability issues in industrial control systems. SCADA vendor Wonderware admitted that Redmond’s Meltdown patch made its Historian product wobble. “Microsoft update KB4056896 (or parallel patches for other Operating System) causes instability for Wonderware Historian and the inability to Read More ›

Maxwell’s Demon (sometimes, “Max”) has long been a fictional device for discussing how if we have access to information we can manipulate molecular scale particles to extract work. Now, physics dot org is discussing a case: >>Physicists have experimentally demonstrated an information engine—a device that converts information into work—with an efficiency that exceeds the conventional second law of thermodynamics. Instead, the engine’s efficiency is bounded by a recently proposed generalized second law of thermodynamics, and it is the first information engine to approach this new bound . . . . [R]ecent experimental demonstrations of information engines have raised the question of whether there is an upper bound on the efficiency with which an information engine can convert information into work.

Let’s follow up our earlier Sci-Tech Newswatch on the Meltdown-Spectre MPU architecture flaw issue. (We see here just how hard it is to create a robust, complex design that can readily be adapted to changes in the environment. Besides, a heads up on a big but under-reported story is helpful.) In a new Jan 15, 2018 report on Meltdown in The UK’s The Register, we may read: >>Patches for the Meltdown vulnerability are causing stability issues in industrial control systems. SCADA vendor Wonderware admitted that Redmond’s Meltdown patch made its Historian product wobble. “Microsoft update KB4056896 (or parallel patches for other Operating System) causes instability for Wonderware Historian and the inability to access DA/OI Servers through the SMC,” an advisory Read More ›

According to SciTech Daily in a January 3, 2018 article, Tabby’s star, aka KIC 8462852, has had a mysterious brightening and dimming cycle.  (Such a cycle, of course raises the interesting thought of the erection of a Dyson Sphere or a similar megastructure.) As the article reports: >>A team of more than 200 researchers, including Penn State Department of Astronomy and Astrophysics Assistant Professor Jason Wright and led by Louisiana State University’s Tabetha Boyajian, is one step closer to solving the mystery behind the “most mysterious star in the universe.” KIC 8462852, or “Tabby’s Star,” nicknamed after Boyajian, is otherwise an ordinary star, about 50 percent bigger and 1,000 degrees hotter than the Sun, and about than 1,000 light years Read More ›
