报告简介:
Audio classification (e.g. audio scene analysis, audio event detection and audio tagging) have a variety of potential applications in security surveillance, intelligent sensing for smart homes and cities, multimedia search and retrieval, and healthcare. This research area is under rapid development recently, having attracted increasing interest from bothacademiaandindustrialists.In this talk, wewill present some recent and new development for several challenges related to this topic, including data challenges (e.g. DCASE challenges), acoustic modelling, feature learning, dealing with weakly labelled data, and learning with noisy labels. We will show some latest results of our proposed algorithms, such as the attention neural network algorithms for learning with weakly labelled data,and their resultson AudioSet – a large scale dataset provided by Google,as compared with several baselinemethods. We will also use some sound demos to illustrate the potentials of our proposed algorithms.
