OpenLORIS-Object

This is the implementation of the following paper: OpenLORIS-Object: A Dataset and Benchmark towardsLifelong Object Recognition

Requirements

The current version of the code has been tested with following libs:

• pytorch 1.1.0
• torchvision 0.2.1
• tqdm
• visdom
• Pillow

Install the required the packages inside the virtual environment:

$ conda create -n yourenvname python=3.7 anaconda
$ source activate yourenvname
$ pip install -r requirements.txt

Data Preparation

Step 1: Download data following Google Drive.

Step 2: Run following scripts:

 python3 benchmark1.py
 python3 benchmark2.py

Step 3: Put train/test/validation file under ./img. For more details, please follow note file under each sub-directories in ./img.

Step 4: Generate the .pkl files of data.

 python3 pk_gene.py
 python3 pk_gene_sequence.py

Quickly get hands on

You can directly use scripts on 9 algorithms and 2 benchmarks (may need to modify arguments/parameters in .bash files if necessary):

bash clutter.bash
bash illumination.bash
bash pixel.bash
bash occlusion.bash
bash sequence.bash

Running Benchmark 1

Individual experiments can be run with main.py. Main option is:

python3 main.py --factor

which kind of experiment? (clutter|illumination|occlusion|pixel)

Running Benchmark 2

The main option to run benchmark2 is:

python3 main.py --factor=sequence

Running specific baseline methods

• Elastic weight consolidation (EWC):

main.py --ewc --savepath=ewc

• Online EWC:

main.py --ewc --online --savepath=ewconline

• Synaptic intelligence (SI):

main.py --si --savepath=si

• Learning without Forgetting (LwF):

main.py --replay=current --distill --savepath=lwf

• Deep Generative Replay (DGR):

main.py --replay=generative --savepath=dgr

• DGR with distillation:

main.py --replay=generative --distill --savepath=distilldgr

• Replay-trough-Feedback (RtF):

main.py --replay=generative --distill --feedback --savepath=rtf

• Cumulative:

main.py --cumulative=1 --savepath=cumulative

• Naive:

main.py --savepath=naive
