## Abstract

• FSCIL: It requires CNN models to incrementally learn new classes from very few labelled samples, without forgetting the previously learned ones.
• TOPIC: Topology-preserving knowledge incrementer framework, which is proposed to mitigates the forgetting of the old classes by stabilizing NG’s topology and improves the representation learning for few-shot new classes by growing and adapting NG to new training samples.

## Few-Shot Class-Incremental Learning

• a stream of training sets $D^{(1)}, D^{(2)}, \dots$, and for each training set $D^{(t)}$, $L^{(t)}$ is the set of classes of $D^{(t)}$.
