WikiSilo bases and forksWikiSilo theory is a minimalist epistemology that supports a unifying discipline within academia. It is supported by the WikiSilo tool (from wikisilo.org), and Wikimergic is its first client.

History:

  • The Emergic Approach is loosely defined for unifying cognitive modeling.
  • Wikimergic (a product of the Emergic Approach) is used to document (or house) the abstract Emergic Approach. It includes WikiSilo components, and the concrete Emergic Cognitive Model.
  • WikiSilo becomes a minimalist version of the Emergic Approach for science in general. It is housed in the master root level 0 WikiSilo named Wikisilo at wikisilo,org, Simultaneously, Wikimergic has extensions of WikiSilo theory for unifying cognitive modeling.
  • Open-form thinking updates mostly Wikimergic, but WikiSilo as well. Wikimergic becoming suitable for unifying all of science, academia, general learning and decision making. A tool for unifying the world! Nevertheless, because it currently is concretized by ECM, it appears to be targeted for unifying computational modeling.

Three SilosAbstract: WikiSilo.org (or simply Wikisilo) distributes free software tools and content that support a unifying discipline within academia. This involves a hierarchy of WikiSilos at ever increasing levels, each acting as a unifying base to their unifying forks.

Dendritic+ Processing in an Emergic Network Model of Narrow Slit Viewing (Poster)

Leibovitz & West (2013) Dendritic+ Processing in an Emergic Network Model of Narrow Slit Viewing (POSTER)Leibovitz, D. P. & West, R. L. (2013) Dendritic+ Processing in an Emergic Network Model of Narrow Slit Viewing. Poster presented to the the 12th International Conference on Cognitive Modeling (ICCM 2013), Ottawa: Carleton University. [doi: 10.13140/RG.2.1.2849.2002] (pdf)

Abstract: Accounting for dendritic+ processing facilitates richer neural encoding schemes that can ultimately lead to simpler networks while improving their neurobiological plausibility. Dendritic+ processing is an example of several modeling tradeoffs: how local complexifications can improve global simplicity, and how functional network circuitry can be traded against representational circuitry. This is demonstrated within a model of narrow slit viewing based on an Emergic Network architecture (Leibovitz & West, 2013).

Leibovitz, D. P. & West, R. L. (2013) Emergence of Border & Surface Completion (both Spatial and Temporal) in a Flowcentric Model of Narrow Slit Viewing. Invited talk presented to the 12th International Conference on Cognitive Modeling (ICCM 2013), Ottawa: Carleton University. [doi: 10.13140/RG.2.1.2169.2647] (PPTX; PDF)

Abstract: In this talk, we describe a Leibovitz & West (2013) Emergence of Border & Surface Completion (Talk)model of narrow slit viewing that deals with both spatial and temporal completion for borders and surfaces. The model is based on functionality derived from the dynamic interactions of a neural model. We contrast this model with FACADE, which models vision using neural models of modules corresponding to functionality.

Abnormal Science for Abnormal Perception: A Case for Theoretical Cognitive Science via a Case Study of Narrow Slit Viewing

Leibovitz, D. P. (2013+) Abnormal Science for Abnormal Perception: A Case for Theoretical Cognitive Science via a Case Study of Narrow Slit Viewing. Working Paper, pp. 1-7. [doi: 10.13140/RG.2.1.3731.8889] (PDF)

Leibovitz (2013+) Abnormal Science for Abnormal PerceptionAbstract: Anorthoscopic perception is good perception under abnormal viewing conditions. One such scenario is when a wider view of the world is perceived than can be sensed at any one time when looking through a narrow slit. Thus, narrow slit viewing and aperture viewing are common nicknames for this phenomenon. Somehow, visual information must be integrated across viewpoints and one fundamental issue is whether this occurs at the finer-grained locus of sensation, or the larger-grained locus of perception. This paper supports a fine-grained sensory model (Leibovitz, 2013a).

The wider view of abnormal perception will also be used as a metaphor to the unified view of theoretical science as compared to the experimental branch. While analyzing, modeling and theorizing are epistemic activities of both branches, their goals and hence nature will differ. This paper will summarize such differences and introduce theoretical cognitive science via a case study. One surprising difference is that abnormal or holistic analysis requires not only greater epistemic breadth, but must also induce finer ontological grains.

An epistemic problem for holistic analysis is in determining the wider scope applicable for the study of a target phenomenon. This is where theory can inform data. In this paper, we use an ontological, fine-grained and unified theory of cognition (Leibovitz, 2013b) to scope out the relevant neurobiological structures and related phenomena that bear on the target phenomenon of anorthoscopic perception.

Finally, this paper constitutes the theoretical analysis of alternative theories and phenomenon in support for our own theory of narrow slit viewing (Leibovitz, 2013a). In essence, we exemplify abnormal science over abnormal perception, i.e., of theoretical cognitive science for anorthoscopic perception.

Leibovitz, D. P. (2013) Flowcentric Model of Narrow Slit Viewing in an Irregular Retina with Blind Spots, Eye Motion, Blinks and no Smear: Base Model Changes, Test Details and Test Results. Working Paper, pp. 1-7. [doi: 10.13140/RG.2.1.2224.5606] (PDF)

Abstract: A computational model of narrow slit viewing is tested under conditions involving a heterogeneous retina with blind spots, while undergoing eye motion and eye blink. The model demonstrates spatial and temporal forms of filling-in, image stability and lack of smear. At a neural level, the model exemplifies flowcentric behaviour.

The model is based on the Emergic Cognitive Model (ECM) (Leibovitz, 2013a, 2013b). ECM is a unified cognitive model and this paper describe the non-cognitive changes made to support and highlight anorthoscopic behaviour. The model is tested against a simplified stimulus as well as an ecological one in order to demonstrate specific model abilities. Additionally, this paper specifies the testing details and provides the simulation results with minimal interpretation as they are further analyzed by Leibovitz (2013c, 2013d).

Leibovitz, D. P. (2013) Wikimergic: unifying the science of brain and mind according to the Emergic Approach. WikiSilo accessed July 15, 2013 from http://en.wikimergic.org. Accessed September 7, 2015 from http://web.archive.org/web/20130703150953/http://wikimergic.upwize.com/wiki/Main_Page.

Abstract: Wikimergic logoWikimergic is a WikiSilo. Both are theories, methodologies, frameworks, tools and approaches for collaboratively unifying science. However, a WikiSilo is a minimalist and pure epistemology unconcerned with the nature of reality, while Wikimergic is used for explaining change, behaviour and time. This item publicizes the availability of Wikimergic as a product.
