For this, the method of class featuring information compression (CLAFIC) [1] was used, introducing some significant improvements in computer medical diagnosis, which by its very nature is a pattern recognition problem. A unique subspace characterizes each class at every decision stage, and the most prominent class features are selected. Thus the symptoms which best distinguish hyperthyroidism are extracted at every step and the number of tests required to reach a diagnosis is reduced.","PeriodicalId":120916,"journal":{"name":"IEEE Trans.

If all the statistics of the problem are known, Bayes' classification scheme yields the minimum probability of error. If, instead, the statistics are not known and one is given only a labeled training set, it is known that the nearest neighbor rule has an asymptotic error no greater than twice that of Bayes' rule. Here the (k,k?) nearest neighbor rule with a reject option is examined. This rule looks at the k nearest neighbors and rejects if less than k? of these are from the same class; if k? or more are from one class, a decision is made in favor of that class. The error rate of such a rule is bounded in terms of the Bayes' error rate.","PeriodicalId":120916,"journal":{"name":"IEEE Trans. Syst. Sci.

It was designed as a tool for the evaluation of flight hardware and also to provide insight into the specialized nature of an urban transportation system such as the one envisioned for the Northeast Corridor. The actions of aircraft are treated in the high level of detail characteristic of an urban shuttle system with its constraints and limitations. Considerations included: 1) variable passenger demands, 2) dispatching decisions, 3) takeoff and airspace regulations, 4) variations in interfering aircraft traffic, and 5) off-corridor services. The implementation allows for simulation and analysis of aircraft and passenger movements and the consequent interactions. Output is generated in terms of the realistic and useful figures of cost, revenue, and systems performance needed to evaluate each phase of the STOL operation. The model was written in the general purpose simulation system language.","PeriodicalId":120916,"journal":{"name":"IEEE Trans. Syst. Sci.

In general, the form of the density mixtures is not reproducing, invoking the need for unlimited system storage requirements. One suboptimal method for achieving limited storage is to restrict the uncertain parameters in question to come from finite sets of values. An alternate method is proposed for a class of problems and its performance is shown to converge to that of the optimum unlimited storage system. A generalization of the procedure is also discussed.","PeriodicalId":120916,"journal":{"name":"IEEE Trans. Syst. Sci.

Transient response and frequency response both indicate that the eye tracking behavior relative to the target is independent of head movement. The explanation of this phenomenon is pursued. It seems most likely that the vestibulo-ocular reflex, the eye movements elicited by head rotation, plays an essential role. Compensation for head motion is accomplished by this reflex at relatively high frequencies, making visual fixation on stationary objects quite easy. The dynamics of head motion are also investigated. Unusual nonlinear responses are found at high frequencies. Namely, the response frequency is slightly lower than that of the target. A model of the whole system is proposed.","PeriodicalId":120916,"journal":{"name":"IEEE Trans. Syst. Sci.
