In addition, an unsupervised layerwise pretraining followed by standard backpropagation training of a deep network (known as a deep belief network) results in further increase of 2-4% in classification accuracy. Effects of implementation parameters such as types of features and number of adjacent frames as additional features are found to be significant on classification accuracy.", keywords = "acoustic event classification;deep learning;deep neural networks;deep belief networks", title = "{R}ecognition of {A}coustic {E}vents {U}sing {D}eep {N}eural {N}etworks", url = "https://ieeexplore.ieee.org/stamp/stamp.jsp?tp={{\&}}arnumber=6952140{{\&}}tag=1", year = "2014", }
