We present CoCoX (short for Conceptual and Counterfactual Explanations), a model for explaining decisions made by a deep convolutional neural network (CNN). In Cognitive Psychology, the factors (or semantic-level features) that humans zoom in on when they imagine an alternative to a model prediction are often referred to as fault-lines. Motivated by this, our CoCoX model explains decisions made by a CNN using fault-lines. Specifically, given an input image I for which a CNN classification model M predicts class cpred, our fault-line based explanation identifies the minimal semantic-level features (e.g., stripes on zebra, pointed ears of dog), referred to as explainable concepts, that need to be added to or deleted from I in order to alter the classification category of I by M to another specified class calt. We argue that, due to the conceptual and counterfactual nature of fault-lines, our CoCoX explanations are practical and more natural for both expert and non-expert users to understand the internal workings of complex deep learning models. Extensive quantitative and qualitative experiments verify our hypotheses, showing that CoCoX significantly outperforms the state-of-the-art explainable AI models.

AbstractThe purpose of this paper is to explore the connection between expressivism and disagreement. More in particular, the aim is to defend that one of the desiderata that can be derived from the study of disagreement, the explanation of ‘crossed disagreements’, can only be accommodated within a semantic theory that respects, at the meta-semantic level, certain expressivistic restrictions. We will compare contemporary dynamic expressivism with three different varieties of contextualist strategies to accommodate the specificities of evaluative language –indexical contextualism – truth-conditional pragmatics –, pragmatic strategies using implicatures, and presuppositional accounts. Our conclusion will be that certain assumptions of expressivism are necessary in order to provide a semantic account of evaluative uses of language that can allow us to detect and prevent crossed disagreements.

The author examines, using the example of a concept-proposition, multiple manifestations of the connection between a mental unit and units of a language system, argues that the principle of structuring knowledge, characteristic of a proposition, is found in the semantic structure of a sentence, a word-formation nest, in the logic of lexical metonymy, in the logic of transferring definitions, as well as in the ability of a noun to represent knowledge of a propositional nature in speech, concludes that there is a deep commonality of mental and linguistic activity. The semantic structure of the sentence and the structure of the syntactic proposition are isomorphic to the structure of the mental proposition. The vectors of the transfer of the definition from one term of the sentence to another, as well as to the designation of the entire situation, often have propositional logic and are closed by the framework of one sentence. Propositional logic is observed in many word-building nests, especially consistent with the structure of nests organized by a polyactant verb. Among the verbal derivatives in the nest, the percentage of lexemes that name the components of the corresponding situation is significant, in some cases - all the main components of the situation. At the lexico-semantic level, the projection of a proposition on the phenomenon of metonymy is described. Among the models of transference, a variety is highlighted, called propositional metonymy. It includes transfers of the name, the vectors of which (shift of the focus of attention) reflect the structure of the proposition. Another manifestation of the connection between a proposition and linguistic units, considered in the article, is the facts of using a single noun in speech of any lexical and grammatical semantics to represent all situations of any structural complexity. The realized perspective of the research (from the mental unit to linguistic units and processes that reveal with it a certain isomorphism in the logic of categorization and conceptualization of knowledge) allows us to reveal an important line of interaction between the mental and linguistic levels.

In this project, we try to do justice to the grammatical phenomenon of the current German language, which we want to explain in this research. This study deals with the topic of attribute theorems as a prtotypic type of relative clauses in contemporary German, not only from the grammatical or syntactic level, but also from the semantic level. The presented work thus covers the most important rules of the relative clause as an attribute with regard to: a) Construction and formation of the attribute theorem as a prototypical type of relative clauses in German. b) Meaning and use of attribute theorem as a prototypical type of relative clauses in German.

Color And Light

The article is devoted to the analysis of the techniques of color painting and light painting in the story of the neorealist writer I.A. Bunin “The Mad Artist”. The relevance is due to the fact that in the modern education system, more attention is paid to innovative pedagogical receptions designed to optimize the educational process and ensure greater independence in work. In particular, interest in case technology is growing. The purpose of the article is the philological analysis of the story of I.A. Bunin’s “The Mad Artist” with the use of case technology techniques. The authors of the article take a case teaching the analysis and assessment of the situation as the basis for working with the text of the Bunin story. Based on it, the article presents an analysis of the linguistic parameters of a literary text and the means of their representation at the lexico-semantic level, revealing the techniques of color and light painting used by the writer in a work and participating in the implementation of the main principle of constructing a text – antithesis. The analysis is based on the comparative-comparative method, methods of citation and holistic analysis of a literary work. As a result of the research, a Russian language lesson was developed for high school students on the topic «Color and light painting as components of the creator’s world in I.A. Bunin̕ s story “The Mad Artist”» based on the techniques of case technology. The solution of the proposed case contributes to the development of creative and critical thinking of students, the formation of skills to work both individually and in pairs, the development of communicative and linguistic competencies.

This paper presents our continuing work to develop methods to exchange product knowledge in the semantic level in the CAD/CAE domains. We present an approach based on a shared ontology, in which a higher level of ontologies are shared among lower levels of ontologies. Key mapping strategies, such as Equivalency, Attribute Similarity, Composition Similarity, and Inheritance Similarity are defined to map concepts and properties defined in a product design domain and an assembly simulation domain. In addition, a Bridge Ontology is designed to store information obtained from mapping processes and construct a link between different knowledge repositories. An Ontology Mapping Application (OMA) which brings together all these elements has been designed and implemented. It is a Java-based application that allows the user to load source and target ontologies, calculate concept and property similarities between them, display the mapping results, and output a corresponding Bridge Ontology.
