一种基于随机权神经网络的类增量学习与记忆融合方法
A Class Incremental Learning and Memory Fusion Method Using Random Weight Neural Networks
摘要
Abstract
The ability to continual learning(CL)on multiple tasks is crucial for the development of artificial gener-al intelligence.Existing artificial neural networks(ANNs)performing well on a single task are prone to suffer from catastrophic forgetting when sequentially fed with different tasks in an open-ended environment,that is,the connec-tionist models trained on a new task could rapidly forget what was learned previously.To solve the problem,this paper proposes a new metaplasticity-inspired randomized network(MRNet)for the class incremental learning(Class-IL)scenario by relating random weight neural networks(RWNNs)with the relevant working mechanism of biologic-al brain,which enables a single model to learn and remember the unknown task sequence without accessing old task data.First,a general continual learning framework with the closed-form solution is constructed in a feed-forward manner to effectively accommodate new categories emerging in new tasks;Second,a memory-related weight import-ance matrix is formed by referring to the property of synapses,which adaptively adjusts network parameters to avoid forgetting;Finally,effectiveness and efficiency of the proposed method are demonstrated in the class incre-mental learning scenario with 5 evaluation metrics,5 benchmark task sequences,and 10 comparison methods.关键词
