pydex 0.0.9

A Python package for optimal experiment design.

Python Design of Experiments

An open-source Python package for optimal experiment design, essential to a modeller's toolbelt. If you are someone who develops a model of any kind, you will relate to the challenges of estimating its model parameters. This tool will help design maximally informative experiments for collecting data to calibrate your model. This package is a simple and powerful toolkit you must have. With an intuitive syntax and helpful documentation, it should take you little time to start designing optimal experiments for estimating the parameters of your model.

Installation

• PyPI

  $ pip install pydex
  

Quick Start

• Demo of basic features.
• Example of experimental design for differential equation models.

Features:

1. Strive to be as simple as possible to use, but not simpler.
2. Designs continuous experimental designs.
3. Interfaces to optimization solvers through scipy, and cvxpy.
4. Convenient built-in visualization capabilities.
5. Supports virtually any model, as long as it can be written as a Python function.

Dependencies:

1. matplotlib: used for visualization.
2. numdifftools: used for numerical estimation of parameter sensitivities.
3. scipy: used for interfacing with numerical optimizers.
4. cvxpy: used for interfacing with numerical optimizers.
5. pickle: for saving objects (results, data, etc.).
6. dill: for saving objects with weak-references.
7. python 3.x: a core package.
8. numpy: a core package for basic array manipulations.
9. corner: a package for visualizing high-dimensional data points in a corner plot
10. emcee: a package for Bayesian Inference using a Markov Chain Monte Carlo (MCMC) method

Examples

In this repository, you will find examples of designing optimal experiments for a wide range of models, defined explicitly, and implicitly through the solution of a system of ordinary differential equations. Currently, there are examples for using scipy and pyomo for integrating the ODE models. Syntax for solution, visualization, and saving & loading progress are shown in the examples.
