英国赫尔大学科学家大卫·奇期默研究开发出控制害虫的计算机系统。该系统使用神经网络,可从背景噪音中分辨出害虫发出的声音。为使害虫控制系统有效工作,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园的传感器相连,如有害虫出现,计算机将迅速处理传感器捕捉的声音,并发出警报。科学家希望这一系统今后不 University of Hull scientist David Odd Moore developed a computer system to control pests. The system uses neural networks to distinguish the sounds of pests from the background noise. To make the pest control system work effectively, scientists first record the unique sounds of each pest, convert them to digital signals, encode them with speech recognition, and store the encoded signals in a neural network. The computer is connected to a field or garden sensor during operation. If a pest is present, the computer will quickly process the sound captured by the sensor and give an alert. Scientists hope this system will not come in the future
