brain-score/brain-score

A framework for evaluating models on their alignment to brain and behavioral measurements (50+ benchmarks)

Brain-Score is a platform to evaluate computational models of brain function on their match to brain measurements in primate vision. The intent of Brain-Score is to adopt many (ideally all) the experimental benchmarks in the field for the purpose of model testing, falsification, and comparison. To that end, Brain-Score operationalizes experimental data into quantitative benchmarks that any model candidate following the BrainModel interface can be scored on.

Note that you can only access a limited set of public benchmarks when running locally. To score a model on all benchmarks, submit it via the brain-score.org website.

See the documentation for more details, e.g. for submitting a model or benchmark to Brain-Score. For a step-by-step walkthrough on submitting models to the Brain-Score website, see these web tutorials.

See these code examples on scoring models, retrieving data, using and defining benchmarks and metrics. These previous examples might be helpful, but their usage has been deprecated after the 2.0 update.

Brain-Score is made by and for the community. To contribute, please send in a pull request.

Local installation

You will need Python = 3.7 and pip >= 18.1.

pip install git+https://github.com/brain-score/vision

Test if the installation is successful by scoring a model on a public benchmark:

from brainscore_vision.benchmarks import public_benchmark_pool

benchmark = public_benchmark_pool['dicarlo.MajajHong2015public.IT-pls']
model = my_model()
score = benchmark(model)

# >  <xarray.Score ()>
# >  array(0.07637264)
# >  Attributes:
# >  Attributes:
# >      error:                 <xarray.Score ()>\narray(0.00548197)
# >      raw:                   <xarray.Score ()>\narray(0.22545106)\nAttributes:\...
# >      ceiling:               <xarray.DataArray ()>\narray(0.81579938)\nAttribut...
# >      model_identifier:      my-model
# >      benchmark_identifier:  dicarlo.MajajHong2015public.IT-pls

Some steps may take minutes because data has to be downloaded during first-time use.

Environment Variables

Variable	Description
RESULTCACHING_HOME	directory to cache results (benchmark ceilings) in, ~/.result_caching by default (see https://github.com/brain-score/result_caching)

Troubleshooting

`ValueError: did not find HDF5 headers` during netcdf4 installation

pip seems to fail properly setting up the HDF5_DIR required by netcdf4. Use conda: `conda install netcdf4`

repeated runs of a benchmark / model do not change the outcome even though code was changed

results (scores, activations) are cached on disk using https://github.com/mschrimpf/result_caching. Delete the corresponding file or directory to clear the cache.

CI environment

Add CI related build commands to test_setup.sh. The script is executed in CI environment for unittests.
