avalanche.training.plugins.MIRPlugin

class avalanche.training.plugins.MIRPlugin(mem_size: int = 200, subsample: int = 200, batch_size_mem: Optional[int] = None)

Maximally Interfered Retrieval plugin, Implements the strategy defined in “Online Continual Learning with Maximally Interfered Retrieval” https://arxiv.org/abs/1908.04742

This strategy has been designed and tested in the Online Setting (OnlineCLScenario). However, it can also be used in non-online scenarios

__init__(mem_size: int = 200, subsample: int = 200, batch_size_mem: Optional[int] = None)

mem_size: int : Fixed memory size subsample: int : Size of the sample from which to look

for highest interfering exemplars

batch_size_mem: intSize of the batch sampled from

the bigger subsample batch
