## ProcessOptimizer
ProcessOptimizer is a fork of scikit-optimize. ProcessOptimizer will fundamentally function like scikit-optimize,
yet developments are focussed on bringing improvements to help optimizing real world processes, like chemistry or baking.
For examples on use, checkout https://github.com/novonordisk-research/ProcessOptimizer/tree/develop/examples.
## Installation
ProcessOptimizer can be installed using `pip install ProcessOptimizer`
The repository and examples can be found at https://github.com/novonordisk-research/ProcessOptimizer
ProcessOptimizer can also be installed by running `pip install -e .` in top directory of the cloned repository.
## How does it work?
This package is intended for real world process optimization problems of black-box functions. This could e.g. be some complex chemical reaction where no reliable analytical model mapping input variables to the output is readily available.
Bayesian optimization is a great tool for optimizing black-box functions where the input space has many dimensions and the function is expensive to evaluate in terms of time and/or resources.
**Notice that this tool is designed to solve minimization problems.** It is therefore important to define the scoring function such that it turns into a minimization problem.
Below is an illustrative example of minimization of the Booth function in 2 dimensions using the `ProcessOptimizer` package. Notice that in real world applications the function would be black box (and typically the input space would have more than 2 dimensions). However, it would still be possible to evaluate the function given a set of input values and thus use the same framework for optimization.
The Booth function is a 2-dimensional function defined by [Booth Function (sfu.ca)](https://www.sfu.ca/~ssurjano/booth.html). In this example uniformly distributed random noise between 0-5% of the function value is added using `np.random`.
```python
def Booth(x0, x1):
return ((x0 + 2 * x1 - 7)**2 + (2 * x0 + x1 - 5)**2) * (1 + 0.05 * np.random.rand())
```
Below is an image of the Booth function on the square 
for i=0,1.
Suppose you are given the task of minimizing the function on the domain only using empirical observations and without any analytical function.
Working with the ProcessOptimizer package you simply define the `Space` and create an `Optimizer` object.
The `Space` object takes a list of dimensions which can either be `Real`, `Integer` or `Categorical`. `Real` dimensions are defined by the maximum and minimum values.
The `Optimizer` object initialized below uses GP (Gaussian Process). This means that after each step a Gaussian Process is fitted to the observations, which is used as a posterior distribution. Combined with an acquisition function the next point that should be explored can be determined. Notice that this process only takes place once n_initial_points of initial data has been aqcuired. In this case `LHS = True` (latin hypercube sampling) has been used as the initial sampling strategy for the first 6 points.
```python
SPACE = Space([Real(0,5), Real(0,5)])
opt = Optimizer(SPACE, base_estimator = "GP", n_initial_points = 6, lhs = True)
```
The optimizer can now be used in steps by calling the `.ask()` function, evaluating the function at the given point and use `.tell()` the `Optimizer` the result. In practise it would work like this. First ask the optimizer for the next point to perform an experiment:
```python
opt.ask()
>>> [3.75, 3.75]
```
Now go to the laboratory or wherever the experiment can be performed and use the values above. In this example the experiment can simply be performed by evaluating the Booth function using the values above:
```python
Booth(3.75, 3.75)
>>> 59.313996676981354
```
When a result has been obtained the user needs to tell the output to the `Optimizer`. This is done using the `.tell()` function:
```python
res = opt.tell([3.75, 3.75], 59.313996676981354)
```
The `res` object returned by tell contains a model of the Gaussian Process predicted mean. This model can be plotted using `plot_objective(res)`. Below is a gif of how the Gaussian Process predicted mean evolves after the first 6 initial points and until 20 points have been sampled in total. The orange dots visualise each evaluation of the function and the red dot shows the position of the expected minimum. In the diagonal of the figure dependence plots are shown. These show how the function depend on each input variable with other input variables kept constant at the expected minimum.
Notice that this is an optimization tool and not a modelling tool. This means that the optimizer finds an approximate solution for the global minimum quickly however it does not guarantee that the Gaussian Process predicted mean is an accurate model on the entire domain.
The best observation against the number of observations can be plotted with `plot_convergence(res)`:

## Contributions
Feel free to play around with algorithm. Should you encounter errors while using ProcessOptimizer, please report them
at https://github.com/novonordisk-research/ProcessOptimizer/issues.
To help solve the issues, please:
- Provide minimal amount of code to reproduce the error
- State versions of ProcesOptimizer, sklearn, numpy, ...

If you would like to contribute by making anything from documentation to feature-additions, THANK YOU. Please open a pull request
marked as *WIP* as early as possible and describe the issue you seek to solve and outline your planned solution.
Pull requests to the develop branch will be automatically tested using pytest and flake8. We'll be happy to help solving potential
issues that could arise here.
