Universality in Amorphous Computing
Petrů, Lukáš ; Wiedermann, Jiří (advisor) ; Janeček, Jan (referee) ; Neruda, Roman (referee)
Amorphous computer is a theoretical computing model consisting of randomly located tiny devices (called nodes) in some target area. The nodes of an amorphous computer can communicate using short-range radio. The communication radius is small compared to the size of the target area. The nodes are all identical, initially have no identi ers, work asynchronously and there is no standard communication protocol. An amorphous computer must work for any number of nodes under reasonable statistical assumptions concerning the spatial distribution of nodes. Moreover, the computation should use very limited amount of memory on each node. For the just described concept of amorphous computer we investigate the question whether a universal computation is possible at all in a corresponding theoretical model. To answer this question, several subsequent steps are performed. In the rst step, we design a formal minimalist model of a node and of the amorphous computer as a whole. In the second step, we develop communication protocol for the amorphous computer. In the last step, we show the universality by simulating a computation of a universal machine. The size of the amorphous computer will depend on the space complexity of the simulated machine. All the previously mentioned steps are described in detail in this work....
Epistemic Limits of (Super)intelligent Systems
Wiedermann, Jiří
Based on epistemic approach to computations we present a new perspective on intelligence. Computations will be seen as processes generating knowledge over the given knowledge domain in accordance with the respective knowledge theory. In this context intelligence will be seen as an ability to gain information and transform it to knowledge used for problem solving. The main result of the paper states that as long as the epistemic domain is finite and fixed then intelligent systems with so-called self-improving theories can be designed which soon on later will reach a state of knowledge about the underlying domain which cannot be improved any further. The system will reach the limits of its own intelligence.
Inconspicuous Appeal of Amorphous Computing Systems
Wiedermann, Jiří
Amorphous computing systems typically consist of myriads of tiny simple processors that are randomly distributed at fixed positions or move randomly in a confined volume. The processors are “embodied” meaning that each of them has its own source of energy, has a “body” equipped with various sensors and communication means and has a computational control part. Initially, the processors have no identifiers and from the technological reasons, in the interest of their maximal simplicity, their computational, communication, sensory and locomotion (if any) parts are reduced to an absolute minimum. The processors communicate wirelessly, e.g., in an airborne medium they communicate via a short-range radio, acoustically or optically and in a waterborne medium via molecular communication. In the extreme cases the computational part of the processors can be simplified down to probabilistic finite state automata or even combinatorial circuits and the system as a whole can still be made universally programmable. From the theoretical point of view the structure and the properties of the amorphous systems qualify them among the simplest (non-uniform) universal computational devices. From the practical viewpoint, once technology will enable a mass production of the required processors a host of new applications so far inaccessible to classical approaches to computing will follow.
Opening the knowledge gate: computations revised
Wiedermann, Jiří
We present a new view of computations - viz. the knowledge generating processes. This approach has many connotations in the area of artificial intelligence, in cognitive sciences, in philosophy, epistemology and methodology of science.
Is There Something Beyond AI? Frequently Emerging, but Seldom Answered Questions about Artificial Super-Intelligence
Wiedermann, Jiří
Using the contemporary theories and views of computing and of cognitive systems we indicate possible answers to the following frequently asked questions about artificial intelligence: (i) what is the "computational power" of artificial cognitive systems?; (ii) are there "levels" of intelligence?; (iii) what is the position of human intelligence w.r.t. the "levels" of intelligence?; (iv) is there a general mechanism of intelligence?; (v) can "fully-fledged" body-less intelligence exist?; (vi) can there exist a sentient cloud? We give qualified arguments suggesting that within the large class of computational models of cognitive systems the answers to the previous question are positive. These arguments are mostly based on the author's recent works related to this problematics.
