  • Publication number: 20230072274
    Abstract: A neuron-level plasticity control (NPC) addresses the issue of catastrophic forgetting in an artificial neural network. The plasticity of a network is controlled at a neuron level rather than at a connection level during training of a new task, thereby conserving existing knowledge. The neuron-level plasticity control evaluates the importance of each neuron and applies a low training speed to integrate important neurons. In addition, a scheduled NPC (SNPC) is provided that uses training schedule information to more clearly protect important neurons.
