Center node: "audio set classification with attention model a probabilistic perspective"
  Abstract: This paper investigate the classification of the Audio Set dataset. Audio Set is a large scale multi instance learning (MIL) dataset of sound clips. In MIL, a bag consists of several instances, and a bag is labelled positive if one or more instances in the audio clip is positive. Audio Set is a MIL dataset because an audio clip is labelled positive for a class if at least one frame contains the corresponding class. We tackle this MIL problem using an attention model and explain this attention model from a novel probabilistic perspective. We define a probability space on each bag. Each instance in a bag has a trainable probability measure for a class. Then the classification of a bag is the expectation of the classification of the instances in the bag with respect to the learned probability measure. Experimental results show that our proposed attention model modeled by fully connected deep neural network obtains mAP of 0.327 on Audio Set dataset, outperforming the Google's baseline of 0.314 and recurrent neural network of 0.325.
