GPlib
=====

A python library for Gaussian Process Regression.

Setup GPlib
-----------

- Create and activate virtualenv (for python2) or
  venv (for python3)

```bash
  # for python3
  python3 -m venv .env
  # or for python2
  python2 -m virtualenv .env

  source .env/bin/activate
```

- Upgrade pip

```bash
  python -m pip install --upgrade pip
```

- Install GPlib package

```bash
  python -m pip install gplib
```

- Matplotlib requires to install a backend to work interactively
  (See https://matplotlib.org/faq/virtualenv_faq.html).
  The easiest solution is to install the Tk framework,
  which can be found as python-tk (or python3-tk) on
  certain Linux distributions.


Use GPlib
----------------------

- Import GPlib to use it in your python script.

```python
  import gplib
```

- Initialize the GP with the desired modules.

```python
  gp = gplib.GP(
    mean_function=gplib.mea.Fixed(),
    covariance_function=gplib.ker.SquaredExponential()
  )
```

- Plot the GP.

```python
  gplib.plot.gp_1d(gp, n_samples=10)
```

- Generate some random data.

```python
  import numpy as np
  data = {
    'X': np.arange(3, 8, 1.0)[:, None],
    'Y': np.random.uniform(0, 2, 5)[:, None]
  }
```

- Get the posterior GP given the data.

```python
  posterior_gp = gp.get_posterior(data)
```

- Finally plot the posterior GP.

```python
  gplib.plot.gp_1d(posterior_gp, data, n_samples=10)
```

- There are more examples in examples/ directory. Check them out!

Develop GPlib
-------------

-  Download the repository using git

```bash
  git clone https://gitlab.com/ibaidev/gplib.git
```

-  Update API documentation

```bash

  source ./.env/bin/activate
  pip install Sphinx
  cd docs/
  sphinx-apidoc -f -o ./ ../gplib
```
