Combining Query Rewriting and Knowledge Graph Embeddings for Complex Query Answering
(Master thesis, 2023-06-01)The field of complex query answering using Knowledge Graphs (KGs) has seen substantial advancements in recent years, primarily through the utilization of Knowledge Graph Embeddings (KGEs). However, these methodologies often ... -
Enhanced biomedical data extraction from scientific publications
(Master thesis, 2023-06-01)The field of scientific research is constantly expanding, with thousands of new articles being published every day. As online databases grow, so does the need for technologies capable of navigating and extracting key ... -
Consistency of LSO with syntactic equality
(Master thesis, 2023-06-01)LSO, Logic of Sentential Operators, is defined by extending first- order logic by sentential quantification and sentential operators. Its semantics is defined by a digraph, with kernels reflecting consistent valuations of ... -
Rule learning of the Atomic dataset using Transformers
(Master thesis, 2023-06-02)Models used for machine learning are used for a multitude of tasks that require some type of reasoning. Language models have been very capable of capturing patterns and regularities found in natural language, but their ... -
Introduction to Lattices and Its Applications in Compute-and-Forward Strategy
(Master thesis, 2023-06-01)The Compute-and-Forward (CF) strategy was proposed as a physical layer network coding (PNC) framework by Nazer and Gastpar in 2011. CF exploits interference to obtain higher rates between users in a network. This thesis ... -
Tail-biting Codes for Lattice Wiretap Coding
(Master thesis, 2023-06-01)The secrecy gain of Construction A lattices obtained by tail-biting rate 1/2 convolutional codes is studied to evaluate the secrecy performance of a lattice in a wiretap channel communication. The higher the secrecy gain, ... -
On Derivative-Free Optimisation Methods
(Master thesis, 2023-05-15)As part of the field of mathematical optimisation, derivative-free optimisation is the study of optimisation methods that are not granted full access to the derivative of the objective function. In this master's thesis, ... -
Reinforcement Learning for Lifelong Multi-Agent Pathfinding in AutoStore system
(Master thesis, 2023-05-25)AutoStore (AS) uses a cubic system for warehouse automation, utilizing robots to retrieve and organize objects in a three-dimensional grid of bins in a Manhattan geometry environment. Lifelong Multi-Agent Pathfinding (LMAPF) ... -
On a New, Efficient Framework for Falsifiable Non-interactive Zero-Knowledge Arguments
(Doctoral thesis, 2023-06-09)Et kunnskapsløst bevis er en protokoll mellom en bevisfører og en attestant. Bevisføreren har som mål å overbevise attestanten om at visse utsagn er korrekte, som besittelse av kortnummeret til et gyldig kredittkort, uten ... -
A general deep reinforcement learning hyperheuristic framework for solving combinatorial optimization problems
(Journal article; Peer reviewed, 2023)Many problem-specific heuristic frameworks have been developed to solve combinatorial optimization problems, but these frameworks do not generalize well to other problem domains. Metaheuristic frameworks aim to be more ... -
