communication mediumIEEE VIS 2018 - VAST Challenge
We describe our analysis of VAST Challenge 2018 Mini-Challenge 1. Our approach combines automatic analysis and interactive exploration. We improve user interaction and introduce new views to support analysis. At the same time, we design a convolutional neural network in order to compute a classifier of bird-singing audio files. The classifier and the interactive exploration tool are used to answer some of the challenge questions. Our analysis suggest that the audio files are most probably not of Pipits and, moreover, if there are Pipits among them, they are represented in minority. This finding indicates a need for further investigation.
