In order to present the instructions as an algorithm, we use a variant of context free grammars (CFG) as an input format. We can exclude overgeneration, if the CFG has no recursion, i.e. no non-terminal can (indirectly) derive to a right-hand side containing itself. The constructed MGs utilize licensors/-ees as a special way of exception handling. A CFG format for a derivation A_eats_B↦∗peter_eats_apples, where A and B generate noun phrases, normally leads to overgeneration, e.\,g., i_eats_apples. In order to avoid overgeneration, a CFG would need many non-terminal symbols and rules, that mainly produce the same word, just to handle exceptions. In our MGs however, we can summarize CFG rules that produce the same word in one item and handle exceptions by a proper distribution of licensees/-ors. The difficulty with this technique is that in most generations the majority of licensees/-ors is not needed, but still has to be triggered somehow. We solve this problem with ϵ-items called \emph{adapters}.}, language = {en} } @misc{RoemerbeimGrabenHuberLiebletal., author = {R{\"o}mer, Ronald and beim Graben, Peter and Huber-Liebl, Markus and Wolff, Matthias}, title = {(Pre-)linguistic Problem Solving based on Dynamic Semantics}, series = {14th IEEE International Conference on Cognitive Infocommunications - CogInfoCom 2023, September 22-23, Budapest, Hungary}, journal = {14th IEEE International Conference on Cognitive Infocommunications - CogInfoCom 2023, September 22-23, Budapest, Hungary}, isbn = {979-8-3503-2565-2}, issn = {2473-5671}, doi = {10.1109/CogInfoCom59411.2023.10397487}, pages = {147 -- 152}, language = {en} } @misc{UhligAlkhasliSchubertetal., author = {Uhlig, Sebastian and Alkhasli, Ilkin and Schubert, Frank and Tsch{\"o}pe, Constanze and Wolff, Matthias}, title = {A Review of Synthetic and Augmented Training Data for Machine Learning in Ultrasonic Non-Destructive Evaluation}, series = {Ultrasonics}, journal = {Ultrasonics}, number = {134}, issn = {1874-9968}, doi = {10.1016/j.ultras.2023.107041}, abstract = {Ultrasonic Testing (UT) has seen increasing application of machine learning (ML) in recent years, promoting higher-level automation and decision-making in flaw detection and classification. Building a generalized training dataset to apply ML in non-destructive evaluation (NDE), and thus UT, is exceptionally difficult since data on pristine and representative flawed specimens are needed. Yet, in most UT test cases flawed specimen data is inherently rare making data coverage the leading problem when applying ML. Common data augmentation (DA) strategies offer limited solutions as they don't increase the dataset variance, which can lead to overfitting of the training data. The virtual defect method and the recent application of generative adversarial neural networks (GANs) in UT are sophisticated DA methods targeting to solve this problem. On the other hand, well-established research in modeling ultrasonic wave propagations allows for the generation of synthetic UT training data. In this context, we present a first thematic review to summarize the progress of the last decades on synthetic and augmented UT training data in NDE. Additionally, an overview of methods for synthetic UT data generation and augmentation is presented. Among numerical methods such as finite element, finite difference, and elastodynamic finite integration methods, semi-analytical methods such as general point source synthesis, superposition of Gaussian beams, and the pencil method as well as other UT modeling software are presented and discussed. Likewise, existing DA methods for one- and multidimensional UT data, feature space augmentation, and GANs for augmentation are presented and discussed. The paper closes with an in-detail discussion of the advantages and limitations of existing methods for both synthetic UT training data generation and DA of UT data to aid the decision-making of the reader for the application to specific test cases.}, language = {en} } @inproceedings{HoffmannWolff, author = {Hoffmann, R{\"u}diger and Wolff, Matthias}, title = {Towards hierarchical cognitive systems for intelligent signal processing}, series = {ICT Innovations 2012, Secure and Intelligent Systems, Ohrid, Macedonia, Sep. 2012, WEB proceedings}, booktitle = {ICT Innovations 2012, Secure and Intelligent Systems, Ohrid, Macedonia, Sep. 2012, WEB proceedings}, publisher = {ICT ACT}, issn = {1857-7288}, pages = {613 -- 618}, language = {en} } @misc{JuKraljevskiNeunuebeletal., author = {Ju, Yong Chul and Kraljevski, Ivan and Neun{\"u}bel, Heiko and Tsch{\"o}pe, Constanze and Wolff, Matthias}, title = {Acoustic Resonance Testing of Small Data on Sintered Cogwheels}, series = {Sensors}, volume = {22}, journal = {Sensors}, number = {15}, issn = {1424-8220}, doi = {10.3390/s22155814}, abstract = {Based on the fact that cogwheels are indispensable parts in manufacturing, we present the acoustic resonance testing (ART) of small data on sintered cogwheels for quality control in the context of non-destructive testing (NDT).

In each case, despite small data, our approach delivers robust performance: All damaged test samples reflecting real-world scenarios are recognized in two one-class classifiers (also called detectors), and one intact test sample is misclassified in binary ones.

Increasing the degree of autonomy and improving cognitive performance, which can be assessed using cognitive and behavioral tests, are two important research trends. The degree of autonomy can be increased using higher-level psychological modules with which needs and motives are taken into account. In our approach we integrate these modules in architecture for an embodied, enactive multi-agent system, such that distributed problem solutions can be achieved. Furthermore, after uncovering some weaknesses in the cognitive performance of traditionally designed agents, we focus on two major aspects. On the one hand, the knowledge processing of cognitive agents is based on logical formalisms, which have deficiencies in the representation and processing of incomplete or uncertain knowledge. On the other hand, in order to fully understand the performance of cognitive agents, explanations at the symbolic and subsymbolic levels are required. Both aspects can be addressed by quantum-inspired cognitive agents. To investigate this approach, we consider two tasks in the sphere of Shannon's famous mouse-maze problem: namely classifying target objects and ontology inference. First, the classification of an unknown target object in the mouse-maze, such as cheese, water, and bacon, is based on sensory data that measure characteristics such as odor, color, shape, or nature. For an intelligent agent, we need a classifier with good prediction accuracy and explanatory power on a symbolic level. Boolean logic classifiers do work on a symbolic level but are not adequate for dealing with continuous data. Therefore, we demonstrate and evaluate a quantum-logic-inspired classifier in comparison to Boolean-logic-based classifiers. Second, ontology inference is iteratively achieved by a quantum-inspired agent through maze exploration. This requires the agent to be able to manipulate its own state by performing actions and by collecting sensory data during perception. We suggest an algebraic approach where both kinds of behaviors are uniquely described by quantum operators. The agent's state space is then iteratively constructed by carrying out unitary action operators, while Hermitian perception operators act as observables on quantum eigenstates. As a result, an ontology emerges as the simultaneous solution of the respective eigenvalue equations.

The advancements can be credited to the ever-increasing availability and miniaturization of computational resources that resulted in exponential data growth. However, because of the insufficient amount of data in some cases, employing machine learning in solving complex tasks is not straightforward or even possible. As a result, machine learning with small data experiences rising importance in data science and application in several fields. The authors focus on interpreting the general term of "small data" and their engineering and industrial application role. They give a brief overview of the most important industrial applications of machine learning and small data. Small data is defined in terms of various characteristics compared to big data, and a machine learning formalism was introduced. Five critical challenges of machine learning with small data in industrial applications are presented: unlabeled data, imbalanced data, missing data, insufficient data, and rare events. Based on those definitions, an overview of the considerations in domain representation and data acquisition is given along with a taxonomy of machine learning approaches in the context of small data.}, language = {en} } @phdthesis{Lindemann, author = {Lindemann, Jens}, title = {Interpretation und Artikulation mit {\"A}ußerungs-Bedeutungs-Transduktoren}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:co1-opus4-38910}, abstract = {In der vorliegenden Arbeit wird die Verwendung von endlichen Transduktoren zur bidirektionalen {\"U}bersetzung zwischen der syntaktischen und semantischen Ebene eines nat{\"u}rlichsprachlichen Dialogsystems untersucht.

Auf Grundlage eines bedeutungsorientierten Sprachmodells wird eine m{\"o}gliche Vorgehensweise zur Modellierung von {\"A}ußerungs-Bedeutungs-Transduktoren vorgestellt. Voraussetzung daf{\"u}r ist eine Sprachdatensammlung, welche zum Beispiel mit Hilfe von Wizard-of-Oz Experimenten erstellt werden kann. F{\"u}r die eigenen Untersuchungen wurden Transduktoren zu Sprach{\"a}ußerungen der deutschen Lautsprache und der Deutschen Geb{\"a}rdensprache konstruiert. Diese semantischen Grammatiken werden sowohl f{\"u}r die Interpretation als auch f{\"u}r die Artikulation eingesetzt. Auf der Perzeptionsseite ist somit die automatische Generierung von semantischen Zeichenketten zu einem gegebenen Worthypothesegraphen realisierbar. Durch die Klammerstruktur der semantischen Zeichenketten kann die dazugeh{\"o}rige Merkmal-Werte-Relation erzeugt werden. Diese Bedeutungsrepr{\"a}sentation wird in der Beispielanwendung unter Verwendung des inversen {\"A}ußerungs-Bedeutungs-Transduktors direkt wieder artikuliert. Zuvor ist jedoch eine Linearisierung der Merkmal-Werte-Relation notwendig. Als Ergebnis dieser beiden {\"U}bersetzungsprozesse erh{\"a}lt man eine sinngem{\"a}ße Wiedergabe zu der gegebenen Sprachzeichenfolge. Durch die Verwendung sprachabh{\"a}ngiger semantischer Grammatiken ist zudem auch eine bedeutungsorientierte {\"U}bersetzung des erkannten sprachlichen Ausdrucks realisierbar. Zus{\"a}tzlich wurde auch ein aktuelles Verfahren zur semantischen Dekodierung mit endlichen Transduktoren umgesetzt, welches ein konzeptuelles stochastisches Sprachmodell nutzt.
