Outline

This paper proposes Saturation Self-Organizing Maps (SatSOM), an extension of the self-organizing map (SOM) to address the problem of catastrophic forgetting in continuous learning environments. SatSOM introduces a novel saturation mechanism that gradually reduces the learning rate and proximity radius of neurons as they accumulate information. This allows well-trained neurons to become fixed, and learning is redistributed to underutilized regions of the map. This aims to enhance knowledge retention in continuous learning while maintaining the interpretability and efficiency of the SOM.
