deNAS - Differential Evolution for Neural Architecture Search

Implementation of DE for NAS, benchmarked in the paper Differential Evolution for Neural Architecture Search accepted to the 1st NAS Workshop at ICLR 2020.

The instructions to setup the benchmarks can be found here.

To run DE on NAS-Bench-101 or NAS-HPO-Bench:

PYTHONPATH=$PWD python3 denas/examples/nas101/run_de_nas101.py

To run DE on NAS-Bench-1shot1:

PYTHONPATH=$PWD python3 denas/examples/nas1shot1/run_de_nas1shot1.py

To run DE on NAS-Bench-201:

PYTHONPATH=$PWD python3 denas/examples/nas201/run_de_nas201.py

Plots can be generated in a similar way, by passing the directory of the stored output files. For example:

PYTHONPATH=$PWD python3 denas/utils/plot_regret.py --path denas/examples/results/cifara

PYTHONPATH=$PWD python3 denas/utils/plot_cdf.py --path denas/examples/results/nas101/cifara

For the above plotting script to work with the output of NAS-Bench-1shot1, the output files need to be additionally preprocessed, for example:

PYTHONPATH=$PWD python3 denas/utils/convert_files.py --path denas/examples/results/nas1shot1/ --ssp 1
