It employs unsupervised learning techniques, specifically deep autoencoders and clustering, to predict wildfires through anomaly detection, utilizing a unique data set comprising historical weather and normalized difference vegetation index data. The techniques employed are some of the most common ...
Anomaly detection has been a typical task in many fields, as well as spectrum monitoring in wireless communication. In this paper, we apply a deep-structure autoencoder neural network to spectrum anomaly detection, and the time-frequency diagram is used as the feature of the learning model. In...
