Learning from a robot: creating synthetic psychologically plausible agents
Due to technological advancements, robots will soon become part of our daily lives and interact with us on a frequent basis. Robot acceptance is important, as it delineates whether users will potentially interact with ...
Decision-making as an encoding-decoding process and its correlation with neuronal activity and behaviour
Un dels objectius més importants de la neurociència teòrica és determinar quins són els principis fonamentals subjacents en el processament de la informació al cervell i en última instància caracteritzar el nexe ...
Effective planning with expressive languages
Classical planning is concerned with finding sequences of actions that achieve a certain goal from an initial state of the world, assuming that actions are deterministic, states are fully known, and both are described ...
Image based analysis and modeling of the detailed cardiac ventricular anatomy
The role of trabeculations and their normal morphological expression in the human heart is still unclear. Clinical studies have shown that excessive trabeculation can cause heart failure due to diastolic and systolic ...
Technology support for scalable and dynamic collaborative learning: a pyramid flow pattern approach
Collaborative Learning is the pedagogical approach that considers social interactions as key means to trigger rich learning processes. Collaborative Learning Flow Patterns define best practices to orchestrate collaborative ...
Interaction and participation in collaborative storytelling systems
Storytelling is one of the oldest models of cultural expression in human history. Thanks to the evolution of information technologies, the Web 2.0 paradigm has impacted in this field: some modern audiences actively participate ...
Data-driven analysis of interactions between pairs and ensembles of coupled dynamics
The characterization of interactions between coupled dynamics from their signals is important for the understanding of real-world systems. The particular aspect of the detection of directional interactions has a central ...
Perceived consistency and coherence in collaborative story worlds
Current information technologies allow users to interact and collaborate to create fictional realities. In this thesis, we explore the role of perceived consistency and coherence in the collaborative creation of fictional ...
Enlargement, subdivision and individualization of statistical shape models: Application to 3D medical image segmentation
This thesis presents three original and complementary approaches to enhance the quality of Statistical Shape Models (SSMs), that improve the accuracy of medical image segmentation in challenging applications. First, we ...
Treatment planning methods for clinical electroporation
Two treatment modalities based on the electroporation phenomenon, electro-chemotherapy and irreversible electroporation, have been developed in the last decades to destroy solid tumors. These treatments are based on the ...
Device-to-device communication and wearable networks harnessing spatial proximity
Spatially proximal devices wanting to exchange information are expected to become more prevalent in wireless networks, rendering the option for direct device-to-device (D2D) communication increasingly important. On the one ...
Knowledge acquisition in the information age: the interplay between lexicography and natural language processing
Natural Language Processing (NLP) is the branch of Artificial Intelligence aimed at understanding and generating language as close as possible to a human’s. Today, NLP benefits substantially of large amounts of unnanotated ...
Feature engineering for author profiling and identification: on the relevance of syntax and discourse
Author profiling and identification are two areas of data-driven computational linguistics that have gained a lot of relevance due to their potential applications in, e.g., forensic linguistic studies, marketing analysis, ...
Reading out neural populations: shared variability, global fluctuations and information processing
Entendre l'origen i la funció de l'activitat de poblacions neuronals, i com aquesta activitat es relaciona amb els estímuls sensorials, les decisions o les accions motores és un gran repte per les neurociències. En ...
Knowledge-based probabilistic modeling for tracking lyrics in music audio signals
This thesis proposes specific signal processing and machine learning methodologies for automatically aligning the lyrics of a song to its corresponding audio recording. The research carried out falls in the broader field ...
From heuristics-based to data-driven audio melody extraction
The identification of the melody from a music recording is a relatively easy task for humans, but very challenging for computational systems. This task is known as "audio melody extraction", more formally defined as the ...
Perceptually-inspired gamut mapping for display and projection tecnologies
The cinema and television industries are continuously working in the development of image features that can provide a better visual experience to viewers; these image attributes include large spatial resolution, high ...
Musical interaction based on the conductor metaphor
Interface metaphors are often used in Human Computer Interaction (HCI) to exploit knowledge that users already have from other domains. A commonly used one in Digital Musical Instruments (DMIs) is the conductor metaphor. ...
Automated cardiac MR image analysis for population imaging
La pràctica clínica i la investigació generen grans quantitats de registres mèdics, incloent-hi imatges. No obstant això, molta informació que podria millorar l'assistència sanitària continua sent inaccessible. Es necessiten ...
Optical flow: related problems
Motion estimation plays a key role in many of the image processing and computer vision problems. This thesis addresses the problem of recovering a dense motion field from a scene through the Calculus of Variations. In ...
