    Voynich Manuscript is a corpus of unknown origin written down in
    unique graphemic system and potentially representing phonic val-
    ues of unknown or potentially even extinct language. Departing from
    the postulate that the manuscript is not a hoax but rather encodes au-
    thentic contents, our article presents an evolutionary algorithm which
    aims to find the most optimal mapping between voynichian glyphs
    and candidate phonemic values.

    Core component of the decoding algorithm is a process of maxi-
    mization of a fitness function which aims to find most optimal set of
    substitution rules allowing to transcribe the part of the manuscript -
    which we call the Calendar - into lists of feminine names. This leads
    to sets of character subsitution rules which allow us to consistently
    transcribe dozens among three hundred calendar tokens into femi-
    nine names: a result far surpassing both "popular" as well as "state
    of the art" tentatives to crack the manuscript. What’s more, by using
    name lists stemming from different languages as potential cribs, our
    "adaptive" method can also be useful in identification of the language
    in which the manuscript is written.

    As far as we can currently tell, results of our experiments indicate
    that the Calendar part of the manuscript contains names from bal-
    toslavic, balkanic or hebrew language strata. Two further indications
    are also given: primo, highest fitness values were obtained when the
    crib list contains names with specific infixes at token’s penultimate
    position as is the case, for example, for slavic feminine diminutives
    (i.e. names ending with -ka and not -a). In the most successful sce-
    nario, 240 characters contained in 35 distinct Voynichese tokens were
    successfully transcribed. Secundo, in case of crib stemming from He-
    brew language, whole adaptation process converges to significantly
    better fitness values when transcribing voynichian tokens whose or-
    der of individual characters have been reversed, and when lists femi-
    nine and not masculine names are used as the crib.

    Abstract: The paper presents a novel method of multiclass classification. The method combines the notions of dimensionality reduction and binarization with notions of category prototype and evolutionary optimization. It introduces a supervised machine learning algorithm which first projects documents of the training corpus into low-dimensional binary space and subsequently uses canonical genetic algorithm in order to find a constellation of prototypes with highest classificatory pertinence. Fitness function is based on a cognitively plausible notion that a good prototype of a category C should be as close as possible to members of C and as far as possible to members associated to other categories. In case of classification of documents contained in a 20-newsgroup corpus into 20 classes, our algorithm seems to yield better results than a comparable deep learning "semantic hashing" method which also projects the semantic data into 128-dimensional binary (i.e. 16-byte) vector space.

    Evolutionary models of ontogeny of linguistic categories and rules



    Abstract


    Language development is a process by means of which a human baby constructs an adequate competence to encode & decode meanings in language of her parents. Computationally it can be described as a trinity of mutually interconnected problems : clustering of all tokens which baby heard into 1) semantic and 2) grammatical categories ; and 3) discovery of grammatical rules allowing to combine the members of diverse equivalence classes into syntactically correct and meaningful phrases. A theoretical, « psycholinguistic » claim of our Thesis is that similary to those theories which explain emergence of cultural or creative thinking as the result of evolutionary process occuring within an individual mind, the emergence of linguistic representations and faculties within a human individuum can be also considered as a case where basic tenets of Universal Darwinism apply. The practical, « cybernetic » aim of the Thesis is to create a computational models of concept learning, part-of-speech induction and grammar induction having comparable performance to existing models but based principially on evolutionary algorithms. It shall be argued that the « fitness function » , which determines the « survival rate » of « candidate grammars » emerging and disappearing in baby’s mind should be based upon the idea that the most fit is such a grammar G which « minimizes the distance »
    between the utterances successfully parsed from linguistic environment E by the application of grammar G and the utterances potentially generated by the grammar G.

    We introduce a novel method for transformation of texts into short binary vectors which can be subsequently compared by means of Hamming distance measurement. Similary to other semantic hashing approaches, the objective is to perform radical dimensionality reduction by putting texts with similar meaning into same or similar buckets while putting the texts with dissimilar meaning into different and distant buckets. First, the method transforms the texts into complete TF-IDF, than implements Reflective Random Indexing in order to fold both term and document spaces into low-dimensional space. Subsequently, every dimension of the resulting low-dimensional space is simply thresholded along its 50th percentile so that every individual bit of resulting hash shall cut the whole input dataset into two equally cardinal subsets. Without implementing any parameter-tuning training phase whatsoever, the method attains, especially in the high-precision/low-recall region of 20newsgroups text classification task, results which are comparable to those obtained by much more complex deep learning techniques.

    Abstract.
    We present two axiomatic and three conjectural conditions which a model inducing natural language categories should dispose of, if ever it aims to be considered as “cognitively plausible”. 1st axiomatic condition is that the model should involve a bootstrapping component. 2nd axiomatic condition is that it should be data-driven. 1st conjectural condition demands that the model integrates the surface features – related to prosody, phonology and morphology – somewhat more intensively than is the case in existing Markov-inspired models. 2nd conjectural condition demands that asides integrating symbolic and connectionist aspects, the model under question should exploit the global geometric and topologic properties of vector-spaces upon which it operates. At last we shall argue that model should facilitate qualitative evaluation, for example in form of a POS-i restricted Turing Test. In order to support our claims, we shall present a POS-induction model based on trivial k-way clustering of vectors representing suffixal and co-occurrence information present in parts of Multext-East corpus. Even in very initial stages of its development, the model succeeds to outperform some more complex probabilistic POS-induction models for lesser computational cost.

    Edit distance is not the only approach how distance between two character sequences can be calculated. Strings can be also compared in somewhat subtler geometric ways. A procedure inspired by Random Indexing can attribute an D-dimensional geometric coordinate to any character N-gram present in the corpus and can subsequently represent the word as a sum of N-gram fragments which the string contains. Thus, any word can be described as a point in a dense N-dimensional space and the calculation of their distance can be realized by applying traditional Euclidean measures. Strong correlation exists, within the Keats Hyperion corpus, between such cosine measure and Levenshtein distance. Overlaps between the centroid of Levenshtein distance matrix space and centroids of vectors spaces generated by Random Projection were also observed. Contrary to standard non-random “sparse” method of measuring cosine distances between two strings, the method based on Random Projection tends to naturally promote not the shortest but rather longer strings. The geometric approach yields finer output range than Levenshtein distance and the retrieval of the nearest neighbor of text’s centroid could have, due to limited dimensionality of Randomly Projected space, smaller complexity than other vector methods.

    Abstract

    Parallel democracy model is a variant of traditional participative democracy
    approach aiming to provide a new method of convergence toward quasi-optimal
    solutions of diverse perennial political and social challenges. Within the
    framework of the model, such challenges are operationalized into variables for
    which the authority can associate possible value. The value which is assigned to
    the variable in a moment T of system’s history is called an active value. Every
    couple {variable, active value} represents a functional property of a given society
    and the genomic vector of such properties can not only describe, but also determine
    the functioning of a society under question. In majority of occidental societies,
    the authority to assign values to variables is delegated to parliament which assigns
    values to variables by means of aggregated voting. The government or other
    institutional bodies subsequently execute actions according to such activated values.
    In almost all modern political systems, the value->variable assignment is
    done in sequential (serial) order for example by voting for one law proposal after
    another during a parliamentary session or a referendum. Any reform of the system
    —an update of multiple variables— is a costly process because a change of
    value for almost any variable requires a new vote which, in majority of societies,
    involves the relocation of vote-givers to a vote giving location during a period dedicated
    to voting. The progress of quasi-perennial storage systems and databases
    in combination with communication networks make it possible to aggregate and
    store information about numbers of votes related to potentially infinite number
    of variables. Therefore a method by means of which the values are activated and
    assigned to variables does not necessarily need to be sequential. Given the condition
    that the act of voting is identic to the incrementation of the chosen value
    stored on the medium, it is not necessary anymore that the decision-makers shall
    meet at one point in time in order to give their vote to the value they want to
    activate. Even the condition that they must meet in one place is weakened since
    the vote-giving place can be purely virtual. Kyberia.sk and kyberia.cz domains are
    domains where first tentatives to implement such a system were implemented «in
    vivo» for a limited set of variables. The aggregated voting of already registered
    kyberia.cz users determine the number of votes which a registration application
    of a new user needs to obtain in order to be accepted. Kyberia.sk senators can
    decide what motto shall be displayed at the top of the page —the option which
    receive the biggest number of votes becomes the active title. Since both variables
    are internal constants of kyberia’s engine, no human intervention is necessary
    after a value becomes variable’s active value and the system automatically reconfigure
    its own code.

    A language-independent method of figure-of-speech extraction is proposed in order to reinforce rhetoric-oriented considerations in natural language processing studies. The method is based upon a translation of a canonical form of repetition-based figures of speech into the language of PERL-compatible regular expressions. Anadiplosis, anaphora, antimetabole figures were translated into the form exploiting the back-reference properties of PERL-compatible regular expression while epiphora was translated into a formula exploiting recursive properties of this very concise artificial language. These four figures alone matched more than 7000 strings when applied on dramatic and poetic corpora written in English, French, German and Latin. Possible usages varying from stylometric evaluation of translation quality of poetic works to more complex problem of semi-supervised figure of speech induction are briefly discussed.

    Abstract. The central problem of roboethics is defined as such: on one hand, robotics aims to construct entities which will transcend the faculties of human beings, on the other hand, some unethical acts should be made impossible to execute for such artificial beings. It can be illustrated on the case of full-fledged AI which is able to reprogram itself, or program other AIs but only in a way that the result shall not lead to the infraction of moral imperatives held by its human conceptors. Thus a programmer of such a system is posed between Skylle of his “aim to conceive an artificial entity able to do almost everything, and more efficiently than a human being” and a Charybde of “the principle of precaution commanding him to constraint the behaviour of such an entity in a way that it would never be able to execute certain acts, like that of a murder, for example”. Therefore the central problem can be also perceived as a form of solution to the problem of trade-off between the amount of “autonomy” of an artificial agent and the extent to which the “embedded ethical constraints” determine the agent’s behaviour. Believing that such a trade-off could be found, our proposal is conceived as a four-folded hybrid “separation of powers” model within which the final output to the solution of ethical dilemma is considered to be the result of mutual interaction of four independent components: 1) “Moral core” containing hard-wired rules analogous to Asimov laws of robotics 2) “Meta-moral Imperative” logically equivalent to Kant’s categoric imperative 3) “Ethico-legal codex” containing an extensible set of normative procedures representing the laws, moral norms and customs present in or induced from agent’s surroundings 4) “Mytho-historical knowledge base” grounding the agent’s representation of « possible states of the world » in the corpora of human generated myths & stories Finally, we will argue that our proposal of two induced & two embedded modules vaguely corresponds to the human morality faculty since it takes into account both its “innate” as well as “acquired” components.

    Goal of this text is to describe the basic notions and methods which could possibly open the path for development, construction and implementation of what we call to be a « Non­Invasive Mind Hacking Apparatus (NIMHA) ». Since NIMHA is – in certain sense – an extension of a « mental prothesis » (MP) first proposed in (Farwell & Donchin, 1988), the introductory part of this text will aspire to explain the functioning of MP and the theoretical notions (i.e. «ERP», «oddball paradigm», «P300») upon which MP is based. Afterwards the crucial difference between «mind reading» and «mind hacking» ­i.e. .«intragression of an intentional will barrier (IWB)» ­ will be introduced and three main arguments for the feasability of such an intragression will be offered.

    The first argument will be based upon a not­yet existing experimental paradigm based on associative priming, the second argument involves the most «state of the art» approaches in the domain of statistics and «signal detection» by means of which one can substantially reduce the number of ERPs neccessary for obtaining the information stored behind IWB and the third argument will concern a huge number of possible – ERP based (CNV, P300, N400) as well as non­-ERP (EDA, Oculometry, NIRS) – based scenario by which one could possibly (and in a noninvasive way) reveal the signal carrying features.

    Finally, some ethical consequences of deployment of NIMHA will be discussed – negative, as well as positive ones

    The aim of this text is threefold: Firstly, to prove to the Teacher that the author of this article (i.e. Student) have sufficiently internalized all the facts presented during UE Neuroimagery. Secondly,Student aims to introduce the notion of «invasivity» as something which should be considered very seriously by someone who seeks an «ideal method» of conducting his future (neuro)scientific experiments towards success.

    But the ultimate aim si to show that certain «philosophical schools» who point out to «invasivity-related aspects» of current neuro-scientific research are not doing so from the position of moralizing savants locked in their ivory towers, but they do so because of concrete and highly-pragmatic reasons related to purest expressions of highest scientific practice.

    Principal thesis of this text states that « invasivity » and « reversibility » aspects of a chosen experimental method should determine experimentator's choice at least as significantly as other aspects like spatial/temporal resolution characteristics, signal/noise ratio or economical feasibility.

    First part of the text is dedicated to highly invasive techniques tissue extraction and analysis by means of electron, multiphoton or confocal microscopes. Post mortem autopsy and chirurgical interventions like vivisesction or lobotomy will be mentioned when discussing this group. Common demoninator of these approaches is that their condition sine qua non of their realisation is non-reversible and fatal degradation of one vital functions of the organism under study or...death.

    Second part of the text is dedicated to somewhat more reversible, nonetheless still very brutal «in vivo» techniques like that of calcic imaging, optic imaging or electrode implantation. Because it is evident that such approaches can inflict severe injuries and suffering of the organisms under study, they will be labeled as «partially reversible quasi in vivo techniques». Contrary to common categorisation of these days, even techniques like PET (positron emission tomography) or X-ray imaging will be included into this middle group of partially invasive techniques. This is due to their high-energy kinship with radioactivity which can without any doubt induce mutations resulting in the disequilibrium of a living system which is commonly known as «loss of health». The loss of this precious equilibrium is the reason why we'll include all the luminescence/fluorescence marker techniques into this category as well.

    The third part of the text aims to bring hope. It will be fully devoted to techniques which can beconsidered as fully reversible: focus will be definitely on Magnetic Resonance Imaging (MRI) and Electroencephalography (EEG) while other non-invasive techniques (NIRS, echography or TCD) will be excluded from the list due to lack of Student's personal experience with these techniques.

    The small part of this final part will be dedicated to «what if?» speculation proposing to use these pure and elegant techniques not only for imaging, but as well as a tool of healing practice.

    Five different versions OpenCV-positive XML haarcascades of zygomatic smile-detectors as well as five SMILEsamples from which these detectors were derived had been trained and are presented hereby as a new open source package. Samples have been extended in an incremental learning fashion, exploiting previously trained detector in order to add and label new elements of positive example set. After coupling with already known face detector, overall AUC performance ranges between 77%-90.5% when tested on JAFFE dataset and <1ms per frame speed of smile detection is achieved when tested on webcam-obtained videos.

    Popis/Comment: Memetics is a new science which is just establishing its relations with other sciences – we’ll glance over few of them. Since huge amount of entities which are called memes belongs also to the set of linguistic signes, it can be expected that the exchange between linguistics and memetics will be fecond. Thus we’ll use basic linguistic terminology, especially the lexicological notion of morpheme defined like « smallest unit having a meaning » as a source of metaphores which could be helpful in interpretation of phonemena which could be labeled as « m emetic » . By using this new heoretical
    framework and by focusing only upon the relations among few «allomemes » used for expressing happiness or amusement, which are for example emoticons like :) , :) or a morpheme « lol » , we’ll try to offer to our reader an illustrous example of our « back to the signs » method which could possibly lead to the formalization of memetics, and thus to her firm establishement at the point of contact between natural and human sciences.
    We’ll show, also, how the formal properties of a memesign – for example its length or the number of possible modalities of its expression influence its fitness, and thus its distribution in population of hosts.
    Database of virtual community kyberia.sk (July 2006 dump) served us as the corpus.

    Popis/Comment: We decided to answer the question « Which elements caused evolution of Serial/Parallel/Independent (Tulving, 1995) model into Memory NeoStructural Inter-Systemic (Eustache & Desgranges, 2008) model ? » in a three folded manner. Firstly, we'll focus the reader's attention upon what is common between SPI and MNESIS, i.e. upon similarities. Afterwards we'll try to enumerate all the differences we have observed between them. And lastly, we'll try to assess the model shift causae (i.e. we'll do our best to point out the phenomena whose observation could have possibly led Eustache&Desgranges to the conception of their new model).

    Popis/Comment: The aim of our study was to show that distributions of hyperlinks within wikipedia corpora implicitly contain information about cultural preferences of its authors. We have transformed wikipedia corpora written in 27 different languages into graph structures whose vertices correspond to wikipedia articles and edges to hyperlinks between these articles. Afterwards we have calculated PageRank vectors for every one of these graphs, thus obtaining so-called “intracultural importance list” for every linguistic community under study. Two datamining experiments were performed with obtained data: “the top country” study indicated that labels of articles concerning countries, related to linguistic community that created these articles are to be found in the top parts of their respective intracultural lists and inversely that the top parts of these lists can be potentially used as a stylometric method of identification of the community which created the corpus. “The world&corpus” study revealed that majority of rankings of articles concerning the countries of reference within intracultural list of a given community significantly correlates with a factual geographic distance between the country of reference and a supposed home country of a linguistic community. Both experiments have indicated presence of morphism between wikipedia hyperlink graph and a factual world of its authors.

    Nazov/Title: The Solution of ???P=NP??? Problem
    Jazyk/Language: EN
    Medium: PDF
    Velkost/size: 206 KiB
    Stran/Pages: 4
    Popis/Comment: In this short text, I'll sketch out two possible answers to the question ' Is P equal to NP?'. Two conjectures, out of which at least one is certainly true (if the law of excluded middle is true). When discussing the P = NP conjecture, two possible approaches will be introduced which could possibly serve to one who will decide to demonstrate that P=NP. One will be less scientific than the other, the other will reveal its effectiveness faster than the one. The first approach – a theoretical one – will point out the usefulness of so-called P-complex 'Power' method in obtaining precious information about the overall (i.e. global) state of the studied system (e.g. a city network in case of Traveling Salesman Problem). The second approach – so-called physical one – will propose so-called Physical Machine able to solve the NP problem by high-paralelity of mutual relations of its basic components. Only a brief advise of epistemologic nature will be given when discussing P NP conjecture
