Resumo
This work aims to investigate different techniques
for the classification of atypical sound events, considering the
accuracy and classification time, in order to find which of these
techniques are most advantageous for surveillance scenarios,
minimizing the possibility of relevant events to go unnoticed.
LDA, QDA, Decision Tree and KNN techniques were compared.
The results obtained indicate that the KNN is the most indicated
classification method for the purposes described.
