This paper presents an automatic meter extraction system which relies on auto-correlation coefficients. The input format for music is MIDI, and we assume that a beat and its ocurrences in the musical sequence are known. As output, our algorithm provides a set of possible metric groupings sorted by a confidence criteria. The algorithm has been tested on several pieces of Rameau and results are e...

In intelligent educational systems, assessment of what the learner is doing is a prerequisite for proper, knowledgeable guidance of the educational process. We propose to use existing techniques from the field of modelbased reasoning for this purpose. This paper describes how a modified version of GDF can be exploited in diagnosing a learner’s problem solving behaviour. The problem solving task...

The high cost associated with the training of forestry machine operators has led to the development of a computerized training environment for this task. Since the emphasis is on training instead of computer graphics, the degree of realism with which we present a forest scene, for example, must be balanced by the available computing power so that the operator's gestures may be reeected, in real...

sharply against the white tile. The space ahead opened into a crosswalk bridging the hospital towers over the street below. Light streamed in through the large glass panels, painting the ground yellow. White coats littered the corridor, and I glanced beyond them at the cars passing underneath. They felt distant and small. Inside the room, Mr. Lucas sat on the bed folding his brother’s clothes. ...

An improved version of the function estimation program GDF is presented. The main enhancements of the new version include: multi-output function estimation, capability of defining custom functions in the grammar and selection of the error function. The new version has been evaluated on a series of classification and regression datasets, that are widely used for the evaluation of such methods. I...
