神经网络是一种信息处理系统它相仿于生物的大脑结构和功能而构成的,分为人工神经网络(ANN)和生物神经网络(BNN)。在模拟、数字处理机制上,人工神经网络与传统的数字计算机有着根本的不同,它擅长于对大规模的数字量或模拟量进行集体运算和并行处理的特点,并具有很强的学习能力、兼容性、可靠性和自适应。 Neural network is an information processing system which is composed of biological brain structure and function. It is divided into artificial neural network (ANN) and biological neural network (BNN). Artificial neural network is fundamentally different from the traditional digital computer in the analog and digital processing mechanism. It is good at the characteristics of collective operation and parallel processing on large-scale digital or analog quantity, and has strong learning ability, Compatibility, reliability and adaptability.
