چکیده

Designing the representation languages for the input,LE, and output, LH, of a learning algorithm is the hardest task within machine learning applications. This paper emphasizes the importance of constructing an appropriate representation LE for knowledge discovery applications using the example of time related phenomena. Given the same raw data { most frequently a database with time-stamped data { rather diierent representations have to be produced for the learning methods that handle time. In this paper, a set of learning tasks dealing with time is given together with the input required by learning methods which solve the tasks. Transformations from raw data to the desired representation are illustrated by three case studies.

Multiprocessor Preprocessing Algorithms for Uniprocessor On-Line Scheduling

Chetto & Chetto [2] presented an algorithm for the online admission control and run-time scheduling of aperiodic real-time jobs in preemptive uniprocessor environments that are executing systems of periodic hard-real-time tasks. This algorithm requires a significant degree of preprocessing of the system of periodic tasks – in general, this preprocessing takes time exponential in the representat...
