Abstract

In recent years, smart beekeeping gained of interest for assisting professionals and beekeepers to preserve the health of bees colonies. This research field requires to develop new methods based on audio processing and supervised or semi-supervised machine learning for remotely monitor beehives to predict the effects of environmental factors (weather, bee parasites, polluting, etc.). As shown in a recent study [6, 3], audio signal can convey accurate information about the state of a beehive through a limited amount of data. Hence, the goal of this internship is to investigate the most relevant and robust audio features which enable to efficiently monitor a beehive from noisy field recordings.

Goals

  • Identifying efficient and robust audio features for supervised and semi-supervised audio classification scenarios.
  • Development and assessment of one or several new techniques using public datasets and new natural recordings provided by Starling Partners company.

Methodology

This research work focuses on the analysis of natural audio beehive field recordings.

First, we propose to consider as a baseline the existing literature related to hand-crafted audio timbre descriptors [6, 4] which offer a large set of features which showed their efficiency for different classification tasks such as music instrument recognition from field recordings [1].

Second, we will propose new robust audio feature extraction methods based on deep convolutional neural networks (i.e. recurrent convolutional neural networks [2]). This approach already obtained excellent prediction results in weakly-supervised scenarios when applied to waveforms or time-frequency representations of audio signal [5].

Finally, we combine the proposed methods with possibly new audio signal enhancement techniques to improve the robustness of the extracted features and to focus on the signal of interest possibly combined with an attention mechanism [7]. With this in mind, we expect to develop a efficient solution that will be comparatively evaluated in terms of accuracy-dimension-complexity with the existing state-of-the-art methods.
