Multi-channel non-negative matrix factorization for overlapped acoustic event detection
Giannoulis P., Potamianos G., Maragos P. (2018)In this paper, we propose two multi-channel extensions of non-negative matrix factorization (NMF) for acoustic event detection. The first method performs decision fusion on the activation matrices produced from independent ... -
Overlapped Sound Event Classification via Multi-Channel Sound Separation Network
Giannoulis P., Potamianos G., Maragos P. (2021)Overlapped sound event classification (SEC) can be a challenging task, especially in scenarios where the number of possible event classes or the number of simultaneous events occurring (polyphony level) are large. In such ... -
Room-localized speech activity detection in multi-microphone smart homes
Giannoulis P., Potamianos G., Maragos P. (2019)Voice-enabled interaction systems in domestic environments have attracted significant interest recently, being the focus of smart home research projects and commercial voice assistant home devices. Within the multi-module ...
