SERKET: An Architecture for Connecting Stochastic Models to Realize a Large-Scale Cognitive Model

To realize human-like robot intelligence, a large-scale cognitive architecture is required for robots to understand the environment through a variety of sensors with which they are equipped. In this paper, we propose a novel framework named Serket that enables the construction of a large-scale generative model and its inference easily by connecting sub-modules to allow the robots to acquire various capabilities through interaction with their environments and others. We consider that large-scale cognitive models can be constructed by connecting smaller fundamental models hierarchically while maintaining their programmatic independence. Moreover, connected modules are dependent on each other, and parameters are required to be optimized as a whole. Conventionally, the equations for parameter estimation have to be derived and implemented depending on the models. However, it becomes harder to derive and implement those of a larger scale model. To solve these problems, in this paper, we propose a method for parameter estimation by communicating the minimal parameters between various modules while maintaining their programmatic independence. Therefore, Serket makes it easy to construct large-scale models and estimate their parameters via the connection of modules. Experimental results demonstrated that the model can be constructed by connecting modules, the parameters can be optimized as a whole, and they are comparable with the original models that we have proposed

A passive GHz frequency-division multiplexer/demultiplexer based on anisotropic magnon transport in magnetic nanosheets

The emerging field of magnonics employs spin waves and their quanta, magnons, to implement wave-based computing on the micro- and nanoscale. Multi-frequency magnon networks allow for parallel data processing within single logic elements whereas this is not the case with conventional transistor-based electronic logic. However, a lack of experimentally proven solutions to efficiently combine and separate magnons of different frequencies has impeded the intensive use of this concept. In this Letter, we demonstrate the experimental realization of a spin-wave demultiplexer enabling frequency-dependent separation of GHz signals. The device is based on two-dimensional magnon transport in the form of spin-wave beams in unpatterned magnetic nanosheets. The intrinsic frequency-dependence of the beam direction is exploited to realize a passive functioning obviating an external control and additional power consumption. This approach paves the way to magnonic multiplexing circuits enabling simultaneous information transport and processing.Comment: 16 pages, 3 figure

Project overview and update on WEAVE: the next generation wide-field spectroscopy facility for the William Herschel Telescope

We present an overview of and status report on the WEAVE next-generation spectroscopy facility for the William Herschel Telescope (WHT). WEAVE principally targets optical ground-based follow up of upcoming ground-based (LOFAR) and space-based (Gaia) surveys. WEAVE is a multi-object and multi-IFU facility utilizing a new 2-degree prime focus field of view at the WHT, with a buffered pick-and-place positioner system hosting 1000 multi-object (MOS) fibres, 20 integral field units, or a single large IFU for each observation. The fibres are fed to a single spectrograph, with a pair of 8k(spectral) x 6k (spatial) pixel cameras, located within the WHT GHRIL enclosure on the telescope Nasmyth platform, supporting observations at R~5000 over the full 370-1000nm wavelength range in a single exposure, or a high resolution mode with limited coverage in each arm at R~20000. The project is now in the final design and early procurement phase, with commissioning at the telescope expected in 2017.Comment: 11 pages, 11 Figures, Summary of a presentation to Astronomical Telescopes and Instrumentation 201

Paraphysical Jurisprudent Massacre Mediation

It is possible and thereby feasible to develop and implement a pragmatic methodology for a preemptive evidentiary system of ‘Paraphysical Jurisprudence’ for mediating the occurrence of massacres. A required comprehensive completion and formalizing of the tools of epistemology (theory of knowledge) already exists and has been tested both ecumenically and scientifically. The evolution of epistemology has followed the historical progression from myth and superstition to logic and reason to empiricism and now finally to the utility of ‘transcendence’ as a tool in knowledge acquisition. An inspiring example from popular culture is illustrated in the 2002 Hollywood film noir “Minority Report” designed by its director to present a ‘plausible future world’ for the year 2054 wherein an elaborate ‘Precrime Unit’ is tested to prevent murder by utilizing a trio of ‘precogs’ bathed in a ‘photonic milk’ able to presciently predetermine impending occurrences of homicide for which the Precrime Police Unit then intervenes to prevent. Disdain for a putative so-called scientific metaphysics by natural philosophers is deeply rooted in modern pragmatic societies; perhaps rightly so as consistency, credibility and lack of a comprehensive theory has been heretofore emphatically lacking. In addition to the major problem of repeatability is the perceived distinction between domains of the physical and so-called ‘spiritual’ as mutually exclusive. In this work a strong case is made for the rigorous viability and near term putative implementation of a system of paraphysical jurisprudence drawing on the utility of a panoply of concepts. The remaining question is when does feasible become practical in the face of a steady increase in the heinous massacre of innocents
