Backpropagation
| Глоссарий по искусственному интеллекту |
A classical method for error propagation when training artificial neural networks (anns). for standard backpropagation, the parameters of each node are changed according to the local error gradient. the method can be very slow to converge although it can be improved through the use of methods that slow the error propagation and by batch processing. many alternate methods such as the conjugate gradient and levenberg- marquardt algorithms are more effective and reliable.

Обратное распространение, русский
Наиболее применяемый способ управляемого обучения, при котором сигнал ошибки на выходе нейронной сети распространяется в обратном направлении: от нейронов выходного слоя к нейронам входного слоя с последующей корректировкой синаптических весов нейронной сети для достижения минимальной выходной погрешности.

Sorties paradox, английский
A classic paradox occasionally used in defense of fuzzy logic methods. an example is zeno`s pile of sand. if you remove a single grain, it is still a pile. repeat the process and, eventually, no pile of sand exists. when does the pile lose its "pileness" since the earlier operation showed that removing a grain of sand does not change the pileness? as with many paradoxes, it relies on loose definitions and/or a specific viewpoint.
Classification tree, английский
A classification tree is a tree-structured model for classifying dates. an observation is presented to the root node, which contains a splitting rule that sub-classifies the observation into one of its child nodes. the process is recursively repeated until the observation "drops" into a terminal node, which produces the classification. figure c.2 on page 52 shows a partial classification tree for blood pressure. see also: decision tree, recursive partitioning.
