Dictionary learning with cone atoms and application to anomaly detection
A Băltoiu, DC Ilie-Ablachim, B Dumitrescu - Signal Processing, 2024 - Elsevier
We propose a variant of dictionary learning (DL) for sparse representations where the atoms
are cones instead of simple vectors. The most convenient vector from a cone, called actual …
