Example to run the codes.

The instruction of commands and take a0910 dataset as an example

Go to the code directory:

cd ICD/ICD

Replace path_prefix by your project_url in ICD/constant.py.

Run baseline

python project_url/ICD/Base/pure_stream_run.py --dataset a0910 --cdm mirt --ctx cuda:2    --savename global --inc_type global

Run incremental method

python project_url/ICD/ICD/pure_stream_inc_run.py --dataset a0910 --cdm ncd --ctx cuda:3 --savename icd_v0 --alpha 0.2 --beta 0.9 --tolerance 0.2 --inner_metrics True --warmup_ratio 0
