Insect Eavesdropper: Revolutionizing Pest Monitoring

The Insect Eavesdropper is a groundbreaking project that leverages machine learning algorithms to detect and identify pest sounds with 96% precision, even for faint sounds produced by pests inside plants. This innovation has the potential to transform pest management in agriculture by enabling early detection and precise monitoring of crop pests.

Overview

The Insect Eavesdropper was developed as part of my research at the Bick Lab at the University of Wisconsin-Madison. It uses advanced machine learning techniques, including DINO models, autoencoders, and transformers, to analyze large volumes of acoustic data. The system identifies intricate patterns indicative of pest activity, providing profound insights into pest behavior and enabling highly effective pest management strategies.

Key Features:

• High Precision: Achieves 96% accuracy in identifying pest sounds.
• Affordable LiDAR Integration: Enhanced species identification accuracy by 30% in challenging environments using affordable LiDAR technology.
• Neural Radiance Fields (NERF): Integrated NERF with LiDAR to further improve species identification accuracy by an additional 30%.
• Real-Time Monitoring: Enables real-time digital monitoring of crop pests via vibrational signals.

Impact and Recognition

The Insect Eavesdropper has received widespread recognition and acclaim:

• Antlion Pitch Competition Winner: Secured first place and $5,000 at the National Entomological Society of America Conference.
• Wisconsin Governor’s Business Plan Contest Semi-Finalist: Advanced to the semi-final round, selected from 52 entries statewide.
