英国赫尔大学科学家大卫·奇期默开发出控制害虫的计算机系统。该系统的核心部件是专门设计的软件,它使用神经网络,可从背景噪音中分辨出害虫发出的声音。为使控制害虫系统有效工作,科学家先将每种害虫独特的声音录下,转换成数字信号,并用语言识别技术将它们编码,然后再将这些编码信号存储在神经网络中。操作时将计算机同田地或花 David Kelly, a scientist at the University of Hull in the UK, issued a computer system to control pests. At the heart of the system is a specially designed software that uses neural networks to distinguish the sound of pests from the background noise. To make the pest control system work effectively, scientists first record the unique sounds of each pest into digital signals, encode them with speech recognition, and store the encoded signals in a neural network.
