This paper discusses the design of a computer based training (CBT) system to support both the improvement of the skills of experienced readers and the training of new staff. This work is timely because recent advances in technology – particularly advances in high-quality computer displays and high-speed networking – hold the promise of delivering significant benefits for mammography. Through th...

In this paper, we address the general problem of identifying convolutive channels when several training sequences are inserted in the transmitted data symbols stream. We analyze the general situation where the training sequences differ from each other. We consider quasi-static channels (i.e. the sampling period is several orders of magnitude below the coherence time of the channel). There are n...

The recent rapid growth of the Internet as a global telecommunications medium has also led to significant innovations in relation to the delivery of education and training. Many aspects of the learning process, from the presentation of information and interpersonal communication, to assessment of learning outcomes and performance, can now be supported using widely accessible Internet-based form...

We propose to use Minimum Divergence(MD) as a new measure of errors in discriminative training. To focus on improving discrimination between any two given acoustic models, we refine the error definition in terms of Kullback-Leibler Divergence (KLD) between them. The new measure can be regarded as a modified version of Minimum Phone Error (MPE) but with a higher resolution than just a symbol mat...

This paper discusses convergence issues when training adaptive critic designs (ACD) to control dynamic systems expressed as Markov sequences. We critically review two published convergence results of critic-based training and propose to shift emphasis towards more practically valuable convergence proofs. We show a possible way to prove convergence of ACD training.

The aim of this study was to create simulation-based tests with credible pass/fail standards for 2 different fidelities of colonoscopy
