## Directories | ||
|
||
[astronet/](astronet/) | ||
|
||
* A neural network for identifying exoplanets in light curves. Contains code for: | ||
* Downloading and preprocessing Kepler light curves. | ||
* Building different types of neural network classification models. | ||
* Training and evaluating a new model. | ||
* Using a trained model to generate new predictions. | ||
|
||
[astrowavenet/](astrowavenet/) | ||
|
||
* A generative model for light curves. | ||
|
||
[light_curve/](light_curve) | ||
|
||
* Utilities for operating on light curves. These include: | ||
* Reading Kepler data from `.fits` files. | ||
* Applying a median filter to smooth and normalize a light curve. | ||
* Phase folding, splitting, removing periodic events, etc. | ||
* [light_curve/fast_ops/](light_curve/fast_ops) contains optimized C++ light | ||
curve operations. | ||
|
||
[tf_util/](tf_util) | ||
|
||
* Shared TensorFlow utilities. | ||
|
||
[third_party/](third_party/) | ||
|
||
* Utilities derived from third party code. | ||
|
||
|
||
# Setup | ||
|
||
## Required Packages | ||
|
||
* **TensorFlow** ([instructions](https://www.tensorflow.org/install/)) | ||
* **Pandas** ([instructions](http://pandas.pydata.org/pandas-docs/stable/install.html)) | ||
* **NumPy** ([instructions](https://docs.scipy.org/doc/numpy/user/install.html)) | ||
* **SciPy** ([instructions](https://scipy.org/install.html)) | ||
* **AstroPy** ([instructions](http://www.astropy.org/)) | ||
* **PyDl** ([instructions](https://pypi.python.org/pypi/pydl)) | ||
* **Bazel** ([instructions](https://docs.bazel.build/versions/master/install.html)) | ||
* **Abseil Python Common Libraries** ([instructions](https://github.com/abseil/abseil-py)) | ||
|
||
## Run Unit Tests | ||
|
||
Verify that all dependencies are satisfied by running the unit tests: | ||
|
||
```bash | ||
bazel test astronet/... astrowavenet/... light_curve/... tf_util/... third_party/... | ||
``` | ||
The code is now located at https://github.com/google-research/exoplanet-ml | ||
