This paper proposes a statistical nonparametric speech synthesis technique based on a sparse Gaussian process regression (GPR). In our previous study, we proposed GPR-based speech synthesis where each frame of synthesis units is modeled by a regression of Gaussian processes. Preliminary experiments of synthesizing several phones including both vowels and consonants showed a potential of the tec...

In this note it is proved that so called one-sided context-sensitive grammars can generate languages which cannot be generated by any context-free grammar. This fact is not quite new. It has been proved in [3], [4] and [5] (as far as the author knows). In [3] it is proved that a special one-sided context-sensitive grammar suggested by Dr. Fris ([1]) generates a language {a m b'"c"; Hn^ m} which...

Aerial respiratory behaviour in Lymnaea stagnalis was operantly conditioned using a procedure that results in long-term memory (LTM) persisting for 1 but not 3 days. By manipulating the snails' post-training environment, i.e. preventing Lymnaea from performing aerial respiratory behaviour, memory persistence was significantly extended. Memory retention, however, is only extended if snails are p...

The recognition and classification of Named Entities (NER) are regarded as an important component for many Natural Language Processing (NLP) applications. The classification is usually made by taking into account the immediate context in which the NE appears. In some cases, this immediate context does not allow getting the right classification. We show in this paper that the use of an extended ...

Applications that use Akogrimo rely on workflows to orchestrate a set of mobile services chosen from those supported within the Akogrimo Virtual Organisation. As the mobile services move around and even temporarily disappear, their behaviour is monitored for context changes of interest to the workflow depending on them. Measuring and monitoring this context information is a challenge at the cen...

Building on the ideas in [Lab] we indicate how the concept of a composition operator may be extended to the context of Haagerup L p-spaces.

This study identifies the meaning of context in recapturing self-care after a stroke or spinal cord injury (SCI). Recapturingdenotes the process of engaging in self-care to regain the ability to participate in self-care activities. Five people who had had a stroke and 6 people with SCI were interviewed 1-3 months after onset. The interviews were open ended and transcribed verbatim. They were an...

The work of the Open Hypermedia Systems Working Group (OHSWG) has lead to the creation of several hypermedia models and a common protocol for Navigational Hypertext. However none of these include a working model of context. In this paper we present how we have extended the Fundamental Open Hypermedia Model (FOHM) to include context and behaviour. We then present Auld Leaky, a lightweight contex...

The scope for information retrieval applications continues to growth to encompass larger and more diverse archives and new computing environments. The consequent increased demands on information retrieval systems continue to motivate research into new and more efficient search technologies. Users of information retrieval systems work in personal and physical contexts, while the documents contai...

Regular tree grammars and top-down tree transducers are extended by random context sensitivity as known from the areas of string and picture generation. First results regarding the generative power of the resulting devices are presented. In particular, we investigate the path languages of random context tree languages.
