Potentials of Learning Entropy for Sub-Nyquist and Sub-Noise Anomaly Detection

Popis výsledku v původním jazyce

Recently, we have noted the intriguing ability of Learning Entropy (LE) with Higher-Order Neural Units (HONUs) to detect abrupt frequency changes in both sub-Nyquist signals and pure noise signals. The concept of the LE and its fundamental element, the Learning Information (LI), is revised and extended. The LI is presented as the logical counterpart of Shannon&apos;s probabilistic information and the LE as its aggregation, e.g. as an average. The approach emphasizes the computational efficiency and analyzability of HONUs with gradient learning, which implies minimal computational and energy requirements for real-time computations. For pure noise, we show that bandpass filtering and principal components improve LE performance to immediately detect frequency changes below the noise level. By demonstrating the ability of LE with linear units to detect anomalies in undersampled signals and also in pure noise, we show the potential of LE for industrial applications and perhaps also for research related to future digital communication systems or advanced analysis of data from distributed sensors in optical transmission infrastructures.
