Low-resource speech translation
(The University of Edinburgh, 2019-12-17)We explore the task of speech-to-text translation (ST), where speech in one language (source) is converted to text in a different one (target). Traditional ST systems go through an intermediate step where the source ... -
On understanding character-level models for representing morphology
(The University of Edinburgh, 2020-01-20)Morphology is the study of how words are composed of smaller units of meaning (morphemes). It allows humans to create, memorize, and understand words in their language. To process and understand human languages, we expect ... -
Understanding and generating language with abstract meaning representation
(The University of Edinburgh, 2020-01-08)Abstract Meaning Representation (AMR) is a semantic representation for natural language that encompasses annotations related to traditional tasks such as Named Entity Recognition (NER), Semantic Role Labeling (SRL), word ... -
Design and evaluation of contracts for gradual typing
(The University of Edinburgh, 2019-11-25)Gradual typing aims to improve the correctness of dynamically typed programs by incrementally adding type information. Sound gradual typing performs static type checking and inserts run-time checks when a type cannot be ... -
Automatic performance optimisation of parallel programs for GPUs via rewrite rules
(The University of Edinburgh, 2019-12-11)Graphics Processing Units (GPUs) are now commonplace in computing systems and are the most successful parallel accelerators. Their performance is orders of magnitude higher than traditional Central Processing Units (CPUs) ... -
Towards efficient support for massive Internet of Things over cellular networks
(The University of Edinburgh, 2019-12-12)The usage of Internet of Things (IoT) devices over cellular networks is seeing tremendous growth in recent years, and that growth in only expected to increase in the near future. While existing 4G and 5G cellular networks ... -
3D data fusion by depth refinement and pose recovery
(The University of Edinburgh, 2019-11-23)Refining depth maps from different sources to obtain a refined depth map, and aligning the rigid point clouds from different views, are two core techniques. Existing depth fusion algorithms do not provide a general ... -
Test time cost sensitivity in machine learning
(The University of Edinburgh, 2019-11-23)The use of deep neural networks has enabled machines to classify images, translate between languages and compete with humans in games. These achievements have been enabled by the large and expensive computational resources ... -
Prosody generation for text-to-speech synthesis
(The University of Edinburgh, 2019-09-30)The absence of convincing intonation makes current parametric speech synthesis systems sound dull and lifeless, even when trained on expressive speech data. Typically, these systems use regression techniques to predict ... -
Social media in health and care co-production
(The University of Edinburgh, 2019-11-23)The future of health and care services in the EU faces the three challenges of the aging population, fiscal restriction, and social inclusion. Co-production offers ways to manage informal care resources to enable them ... -
Neural density estimation and likelihood-free inference
(The University of Edinburgh, 2019-11-23)I consider two problems in machine learning and statistics: the problem of estimating the joint probability density of a collection of random variables, known as density estimation, and the problem of inferring model ... -
Semantics and provenance of configuration programming language μPuppet
(The University of Edinburgh, 2019-11-23)Nowadays computing infrastructures have grown bigger in scale and more complex. Automated configuration management tools have taken the place of traditional approaches of configuration tasks, such as manual configuration ... -
Machine learning for inductive theorem proving
(The University of Edinburgh, 2019-11-23)Over the past few years, machine learning has been successfully combined with automated theorem provers (ATPs) to prove conjectures from various proof assistants. However, such approaches do not usually focus on inductive ... -
Usability evaluation of spoken humanoid embodied conversational agents in mobile serious games
(The University of Edinburgh, 2019-11-23)The use of embodied conversational agents (ECAs) and spoken dialogue systems in serious games offers theoretical advantages such as a more natural interaction with an agent displaying characteristics like personality, ... -
Wide-coverage statistical parsing with minimalist grammars
(The University of Edinburgh, 2019-11-23)Syntactic parsing is the process of automatically assigning a structure to a string of words, and is arguably a necessary prerequisite for obtaining a detailed and precise representation of sentence meaning. For many NLP ... -
Moving beyond parallel data for neutral machine translation
(The University of Edinburgh, 2019-11-23)The goal of neural machine translation (NMT) is to build an end-to-end system that automatically translates sentences from the source language to the target language. Neural machine translation has become the dominant ... -
Machine learning and privacy preserving algorithms for spatial and temporal sensing
(The University of Edinburgh, 2019-11-23)Sensing physical and social environments are ubiquitous in modern mobile phones, IoT devices, and infrastructure-based settings. Information engraved in such data, especially the time and location attributes have ... -
Methodology to sustain common information spaces for research collaborations
(The University of Edinburgh, 2019-11-23)Information and knowledge sharing collaborations are essential for scientific research and innovation. They provide opportunities to pool expertise and resources. They are required to draw on today’s wealth of data to ... -
Learning to make decisions with unforeseen possibilities
(The University of Edinburgh, 2019-11-23)Methods for learning optimal policies often assume that the way the domain is conceptualised— the possible states and relevant actions that are needed to solve one’s decision problem—is known in advance and does not ... -
Deep generative modelling for amortised variational inference
(The University of Edinburgh, 2019-11-23)Probabilistic and statistical modelling are the fundamental frameworks that underlie a large proportion of the modern machine learning (ML) techniques. These frameworks allow for the practitioners to develop tailor-made ...
