摘要: In this paper, the local minima-free conditions of outer-supervised feedforward neural networks (FNN) based on batch-style learning are studied by means embedded subspace method. It is proven that only if rendition number hidden neurons not less than training samples, which sufficient but necessary, satisfied, network will necessarily converge to global minima with null cost, and condition range space signal matrix included in output Is necessary for error surface. addition, under being samples greater neurons, it demonstrated there also exist cost surface first layer weights adequately selected.
