The construction of personalised information systems is becoming more important as the quantity of information to be searched increases. The approach taken in this paper involves the implicit tracking of user behaviour over the long-term, with an emphasis on how the collected information can be processed and interpreted to build up a good user model for the required task. Parallels are drawn be...

Previous work on semantics-based multi-stage programming (MSP) language design focused on homogeneous designs, where the generating and the generated languages are the same. Homogeneous designs simply add a hygienic quasi-quotation and evaluation mechanism to a base language. An apparent disadvantage of this approach is that the programmer is bound to both the expressivity and performance chara...

This paper presents the design and the applica1 tion of asynchronous models of parallel evolutionary algo2 rithms. An overview of the existing parallel evolutionary 3 algorithm (PEA) models and available implementations is 4 given. We present new PEA models in the form of asynchro5 nous algorithms and implicit parallelization, as well as exper6 imental data on their efficiency. The paper also d...

Learning about one’s physical environment is an important task that must be accomplished early in life to be able to successfully navigate and operate. In an attempt to explain infants’ great success in this endeavor at such an early age, it has been proposed that infants are ready-equipped with some basic knowledge of physics. However, it is also possible that infants possess powerful learning...

Regularization is a powerful technique for extracting useful information from noisy data. Typically, it is implemented by adding some sort of norm constraint to an objective function and then exactly optimizing the modified objective function. This procedure often leads to optimization problems that are computationally more expensive than the original problem, a fact that is clearly problematic...

Previous work on semantics-based multi-state programming language design focused on homogeneous and heterogeneous software designs. In homogenous software design, the source and the target software programming languages are the same. In heterogeneous software design, they are different software languages. This paper proposes a practical means to circuit design by providing specialized offshorin...
