  1. 1. Effective Domains and Admissible Domain Representations

    Author : Göran Hamrin; Viggo Stoltenberg-Hansen; Erik Palmgren; Dieter Spreen; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Logic; symbolic and mathematical; domain theory; admissible domain representation; cartesian closure; effective domains; κ-sequential space; limit space; Matematisk logik; Matematik; Mathematics; Logic; symbolic and mathematical; Matematisk logik; Mathematical logic; Matematisk logik;

    Abstract : This thesis consists of four papers in domain theory and a summary. The first two papers deal with the problem of defining effectivity for continuous cpos. READ MORE

  2. 2. Representations of discourse : cognitive and computational aspects

    Author : Nils Dahlbäck; Linköpings universitet; []

    Abstract : This work is concerned with empirical studies of cognitive and computational aspects of discourse representations. A more specific aim is to contribute to the development of natural language interfaces for interaction with computers, especially the development of representations making possible a continuous interactive dialogue between user and system.

  3. 3. Effective Distribution Theory

    Author : Fredrik Dahlgren; Viggo Stoltenberg-Hansen; Dag Normann; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Computable mathematics; computable analysis; domain theory; domain representations; distribution theory.; Mathematical logic; Matematisk logik;

    Abstract : In this thesis we introduce and study a notion of effectivity (or computability) for test functions and for distributions. This is done using the theory of effective (Scott-Ershov) domains and effective domain representations. READ MORE

  4. 4. Word Representations for Emergent Communication and Natural Language Processing

    Author : Mikael Kågebäck; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extractive summarisation; Emergent communication; Deep reinforcement learning; Natural language processing; Word Representations; Deep learning; Machine learning; Artificial neural networks;

    Abstract : The task of listing all semantic properties of a single word might seem manageable at first but as you unravel all the context dependent subtle variations in meaning that a word can encompass, you soon realize that precise mathematical definition of a word’s semantics is extremely difficult. In analogy, humans have no problem identifying their favorite pet in an image but the task of precisely defining how, is still beyond our capabilities. READ MORE

  5. 5. Discrete Stochastic Time-Frequency Analysis and Cepstrum Estimation

    Author : Johan Sandberg; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ambiguity domain; time-frequency analysis; time-frequency representations; covariance function; non-stationary random processes; Speaker recognition; MFCC; cepstrum;

    Abstract : The theory of stochastic time-frequency analysis of non-stationary random processes has mostly been developed for processes in continuous time. In practice however, random processes are observed, processed, and interpreted at a finite set of time points. READ MORE
