mp-time-split

Use Materials Project time-splits for generative modeling benchmarking.

While methods for cross-validating accuracy of materials informatics models is well estabilished (see for example Matbench), evaluating the performance of generative models such as FTCP or imatgen, and many others is less straightforward. Recently, Xie et al. introduced new benchmark datasets and metrics in CDVAE for several state-of-the-art algorithms. This repository acts as a supplement to CDVAE benchmarks, delivering a new benchmark dataset (Materials_Project_Time_Split_52 or MPTS-52) with time-based (5 $\times$ train/val) +train/test splits suitable for cross-validated hyperparameter optimization and subsequent benchmarking via the test split.

MPTS-52 is most comparable to MP-20 from Xie et al., with the difference that up to 52 atoms are allowed and possibly a difference in the unique elements, as no elemental filtering was applied (e.g. removal of radioactive elements).

Quick Start

Installation

conda env create -n mp-time-split -c conda-forge mp-time-split
conda activate mp-time-split

Example

from mp_time_split.core import MPTimeSplit

mpt = MPTimeSplit(target="energy_above_hull")
mpt.load(dummy=False)

for fold in mpt.folds:
    train_inputs, val_inputs, train_outputs, val_outputs = mpt.get_train_and_val_data(
        fold
    )

final_train_inputs, test_inputs, final_train_outputs, test_outputs = mpt.get_test_data()

Output

print(train_inputs.iloc[0], train_outputs)

<table> <tr> <th> `train_inputs.iloc[0]` </th> <th> `train_outputs` </th> </tr> <tr> <td>

Data (e.g. `train_inputs`, `train_outputs`) is sorted by earliest publication year.
The Materials Project ID number is used as the pandas `Series` index. The "mp-" and
"mvc" suffixes are dropped, except that "-" is retained in case of "mvc-" to make it
negative in the index and distinguish between "mp-" and "mvc-" type entries. This is
to make it easy to sort the entries based on the index. Ensure that you apply `abs` to
the index prior to sorting, otherwise the `mvc-` entries will be in the wrong order.

via `mpt.data`.

Installation

Anaconda

Create an environment named (-n) mp-time-split with the Anaconda package mp-time-split intalled from the conda-forge channel (-c).

conda env create -n mp-time-split -c conda-forge mp-time-split

PyPI

Optionally create and activate a conda environment (recommended to use an isolated environment of some kind):

conda env create -n mp-time-split python==3.9.* # 3.7.* or 3.8.* also OK
conda activate mp-time-split

Install the mp-time-split package from PyPI.

pip install mp-time-split

`environment.yml`

In order to set up the necessary environment:

review and uncomment what you need in environment.yml and create an environment mp-time-split with the help of conda:
```
conda env create -f environment.yml
```
activate the new environment with:
```
conda activate mp-time-split
```

Local Installation

NOTE: The conda environment will have mp-time-split installed in editable mode. Some changes, e.g. in setup.cfg, might require you to run pip install -e . again.

Optional and needed only once after git clone:

install several pre-commit git hooks with:
```
pre-commit install
# You might also want to run `pre-commit autoupdate`
```
and checkout the configuration under .pre-commit-config.yaml. The -n, --no-verify flag of git commit can be used to deactivate pre-commit hooks temporarily.
install nbstripout git hooks to remove the output cells of committed notebooks with:
```
nbstripout --install --attributes notebooks/.gitattributes
```
This is useful to avoid large diffs due to plots in your notebooks. A simple nbstripout --uninstall will revert these changes.

Then take a look into the scripts and notebooks folders.

Note

This project has been set up using PyScaffold 4.2.2 and the dsproject extension 0.7.post1.dev8+g43a905e.

To create the same starting point for this repository, as of 2022-06-01 on Windows you will need the development versions of PyScaffold and extensions, however this will not be necessary once certain bugfixes have been introduced in the next stable releases:

pip install git+https://github.com/pyscaffold/pyscaffold.git git+https://github.com/pyscaffold/pyscaffoldext-dsproject.git git+https://github.com/pyscaffold/pyscaffoldext-markdown.git

The following pyscaffold command creates a starting point for this repository:

putup xtal2png --github-actions --markdown --dsproj

Alternatively, you can edit a file interactively and update and uncomment relevant lines, which saves some of the additional setup:

putup --interactive xtal2png
