Over the last decade there has been growing interest in pool-based active learning techniques, where instead of receiving an i.i.d. sample from a pool of unlabeled data, a learner may take an active role in selecting examples from the pool. Queries to an oracle (a human annotator in most...

As dot.com became dot.bomb, the hype that surrounded the meteoric growth of the network economy has given way to realism, or even scepticism, about the potential of ICT as a source of new business models. It is now appropriate to reflect critically on the e-economy hype, and to use this as a way...

One of the key decisions financial institutions have to make as part of their daily operations is to decide whether or not to grant a loan to an applicant. With the emergence of large-scale data-storing facilities, huge amounts of data have been stored regarding the repayment behavior of past...

This study set out to determine various aspects of the agile approaches to software development. These included an investigation into the principles and practices driving these methodologies; determining the applicability of these approaches to the current software development needs; determining...

We believe that the problems of safety, security and resource usage combine to make it unlikely that programmable networks will ever be viable without mechanisms to transfer risk from the platform provider to the user and the programmer. However, we have well established mechanisms for managing...

When planning and designing a policy intervention and evaluation, the policy maker will have to define a strategy which will define the (conditional independence) structure of the available data. Here, Dawid's extended influence diagrams are augmented by including 'experimental design' decisions...

We present a novel method, called the transform likelihood ratio (TLR) method, for estimation of rare event probabilities with heavy-tailed distributions. Via a simple transformation ( change of variables) technique the TLR method reduces the original rare event probability estimation with heavy...

Discrete event simulation modelling has been extensively used in modelling complex systems. Although it offers great conceptual-modelling flexibility, it is both computationally expensive and data intensive. There are several examples of simulation models that generate millions of observations...

A szerzők cikkükben a számítástechnikai hulladékokkal foglalkoznak, számítástechnikai eszközök alatt a számítógép konfigurációk összetevőit értik, tehát számítógépeket (asztali, hordozható, terminál stb.), és perifériáit (monitor, nyomtató, cd-író stb.), valamint...

A bizalom, amely a legegyszerűbb cseréknek is előfeltétele, különös jelentőségre tesz szert az elektronikus piacokon. A szerző kályhaként egy játékelméleti modellből indul ki, hogy megvilágítsa: miként hidalhatják át az alkalmi partnerek az egymás stratégiaválasztásaira...
