-Incremental learning aims to develop artificially intelligent systems that can continuously learn to address new tasks from new data while preserving knowledge learned from previously learned tasks.+Incremental learning aims to develop artificially intelligent systems that can continuously learn to address new tasks from new data while preserving knowledge learned from previously learned tasks.(([[https://arxiv.org/abs/2010.15277|Class-incremental learning: survey and performance evaluation on image classification]]))

-Catastrophic Forgetting(CF)+Catastrophic Forgetting(CF): Learning multiple tasks in sequence, however, remains a substantial challenge for deep learning. When trained on a new task, standard neural networks forget most of the information related to previously learned tasks, a phenomenon referred to as “catastrophic forgetting”(([[https://arxiv.org/abs/1904.07734v1|Three scenarios for continual learning]])). 
 + 
 +===== Scenarios ===== 
 + 
 +There are 3 scenarios on Incremental Learning(([[https://arxiv.org/abs/1904.07734v1|Three scenarios for continual learning]])), including: 
 + 
 +  * Task Incremental Learning 
 +  * Domain Incremental Learning 
 +  * Class Incremental Learning 
 + 
 +===== Methods ===== 
 + 
 +All methods of incremental learning can be concluded into 4 categories(([[https://arxiv.org/abs/1904.07734v1|Three scenarios for continual learning]])). 
 + 
 +  * Task specific components(sub-network per task): **XDG**(Context-dependent Gating) 
 +  * regularized optimization(differently regularizing parameters): **[[deep_learning:incremental_learning:EWC]]**(Elastic Weight Consolidation), **SI**(Synaptic Intelligence) 
 +  * Modifying Training Data(pseudo-data, generate samples): **[[deep_learning:incremental_learning:LwF]]**(Learning without Forgetting), **DGR**(Deep Generative Replay) 
 +  * Using Exemplars(store data from previous tasks): **[[deep_learning:incremental_learning:iCaRL]]**
