This paper presents DCASE 2018 task 4. The task evaluates systems for the large-scale detection of sound events using weakly labeled data (without time boundaries). The target of the systems is to provide not only the event class but also the event time boundaries given that multiple events can be present in an audio recording. Another challenge of the task is to explore the possibility to exploit a large amount of unbalanced and unlabeled training data together with a small weakly labeled…

Sound Event Detection in the DCASE 2017 Challenge
TLDR
Analysis of the systems behavior reveals that task-specific optimization has a big role in producing good performance; however, often this optimization closely follows the ranking metric, and its maximization/minimization does not result in universally good performance.

TLDR
This work addresses Sound Event Detection in the case where a weakly annotated dataset is available for training, and explores an approach inspired by Multiple Instance Learning, in which a convolutional recurrent neural network is trained to give predictions at frame-level using a custom loss function based on the weak labels and the statistics of the frame-based predictions.

TLDR
