Artificial Intelligence-Based System for Simulation of Predator Sound as an Effective way of Reducing Frequency of Harmful Birds’ Infestation in a Rice Farm
Abstract
This paper presents the simulation of predator sound as an effective way of reducing the frequency of rice harmful birds in a rice farm. In this research work, the harmful rice birds called sparrow birds were scared away using the sound of the predator (Squirrel) and also ordinary sound and the birds’ behaviours were observed over a period of two weeks. It was observed that at the initial instance while using the ordinary sound, the birds were scared away and they later returned to the farm. After subsequent scaring with this ordinary sound, the birds could not be scared away again by this ordinary sound since their cognitive abilities could not attach the sound to any previous ugly experience in the past. However, when the predator sound was used to scare away the birds, the birds were also scared away but it was noticed that the number of birds returning to the farm kept reducing until only very few birds could return to the farm. Due to the cognitive abilities of the birds, the harmful sparrow birds had to attach the predator sound to previous ugly experiences and recognise it as a threat and would fly far away from such rice farm. Hence, simulating the right predator sound in a rice farm would scare away harmful birds in a rice farm leaving the beneficial birds to do their insect pest control. In the course of this research work, a convolutional neural network model was designed and trained to recognize the sparrow birds in the rice farm while an algorithm was developed to simulate predator sound and ordinary sound for the scaring of the harmful sparrow birds. The developed convolutional neural network (CNN) model was developed from a pre-trained model called efficientnetb5 through a process of transfer intelligence. Then, the developed CNN model was trained with 2419 pre-processed images of the sparrow birds in google colab platform. The trained model was integrated with an algorithm that used the sound of the predator (squirrel) and ordina
