Improving searchability of automatically transcribed lectures through dynamic language modelling
(2012)
Recording university lectures through lecture capture systems is increasingly common. However, a single continuous audio recording is often unhelpful for users, who may wish to navigate quickly to a particular part of a ...
An end to end solution for complex open educational resources
(2012)
The main objective of this thesis is to provide content creators and educators with a solution that simplifies the process of depositing into digital repositories. We created a desktop tool named ORchiD, Open educational ...
Imulating storyteller-audience interactions in digital storytelling: questions, exchange structures & story objects
(2012)
This work revolves around the design and evaluation of digital storytelling simulating real personal storytelling. Study One was an ethnography, of real storytellers, which revealed types of narratives, dynamism and ...
Epistemic Implementation and The Arbitrary-Belief Auction
(2012-06-22)
In settings of incomplete information we put forward an epistemic framework for designing mechanisms that successfully leverage the players' arbitrary higher-order beliefs, even when such beliefs are totally wrong, and ...
Patch complexity, finite pixel correlations and optimal denoising
(2012-10-07)
Image restoration tasks are ill-posed problems, typically solved withpriors. Since the optimal prior is the exact unknown density of natural images,actual priors are only approximate and typically restricted to small ...
Optimal Parametric Auctions
(2012-06-14)
We study the problem of an auctioneer who wants to maximize her profits. In our model, there are n buyers with private valuations drawn from independent distributions F_1,...,F_n. When these distributions are known to the ...
Integrated Robot Task and Motion Planning in the Now
(2012-06-29)
This paper provides an approach to integrating geometric motion planning with logical task planning for long-horizon tasks in domains with many objects. We propose a tight integration between the logical and geometric ...
Kintinuous: Spatially Extended KinectFusion
(2012-07-19)
In this paper we present an extension to the KinectFusion algorithm that permits dense mesh-based mapping of extended scale environments in real-time. This is achieved through (i) altering the original algorithm such that ...
Throwing Down the Visual Intelligence Gauntlet
(2012)
In recent years, scientific and technological advances have produced artificial systems that have matched or surpassed human capabilities in narrow domains such as face detection and optical character recognition. However, ...
Integrated robot task and motion planning in belief space
(2012-07-03)
In this paper, we describe an integrated strategy for planning, perception, state-estimation and action in complex mobile manipulation domains. The strategy is based on planning in the belief space of probability distribution ...
