Neste artigo, propomos uma nova abordagem de detecção de sinal acústico alvo que é baseada na fatoração de matriz não negativa (NMF). Os vetores de base alvo são treinados a partir do banco de dados de sinais alvo por meio de NMF, e os vetores de entrada são projetados no subespaço abrangido por esses vetores de base alvo. Ao analisar a distribuição do erro de projeção normalizado variável no tempo, o limite ideal pode ser calculado para detectar os intervalos do sinal alvo durante todo o sinal de entrada. Os resultados experimentais mostram que o algoritmo proposto pode detectar o sinal alvo com sucesso em vários ambientes de sinal.

Abstract: In this paper, we propose a novel target acoustic signal detection approach which is based on non-negative matrix factorization (NMF). Target basis vectors are trained from the target signal database through NMF, and input vectors are projected onto the subspace spanned by these target basis vectors. By analyzing the distribution of time-varying normalized projection error, the optimal threshold can be calculated to detect the target signal intervals during the entire input signal. Experimental results show that the proposed algorithm can detect the target signal successfully under various signal environments.
