Abstract: The objective of the proposed research is to enable detection and classification of anomalies in poultry production facilities through sparse, dictionary-based representations of the auditory environment. This research focuses primarily on the detection of respiratory disease in chickens, but should be extensible to other types of problems or conditions that may arise. The scale of the poultry industry creates significant financial potential for the development of signal processing techniques capable of monitoring varying production settings with minimal human intervention. However, there are numerous challenges to the application of audio signal processing in this domain that must be addressed. For example, the vast majority of the data is unlabeled, and it contains significant amounts of noise. Conditions throughout the day also cause short-term changes in the auditory environment, and the aging of the chickens cause drift over the long-term. The proposed work seeks to overcome these challenges through a frozen dictionary approach to disease detection and several novelty detection approaches based on dictionary learning for sparse representations.
