Spatial Impulse Response Analysis and Ensemble Learning for Efficient Precision Level Sensing
arxiv(2024)
Abstract
In this paper, we propose an innovative method for determining the fill level
of containers, such as trash cans, addressing a critical aspect of waste
management. The method combines spatial impulse response analysis with machine
learning techniques, offering a unique and effective approach for sound-based
classification that can be extended to various domains beyond waste management.
By employing a buzzer-generated sine sweep signal, we create a distinctive
signature specific to the fill level of the waste container. This signature is
then interpreted by a specially developed ensemble learning algorithm. Our
approach achieves a classification accuracy of over 90
locally on a development board, eliminating the need to delegate complex
classification tasks to external entities. Using low-cost and energy-efficient
hardware components, our method offers a cost-effective approach that
contributes to sustainable and efficient waste management practices, providing
a reliable and locally deployable solution.
