Operator Discretization Library (ODL) is an open source toolbox for inverse problems written in Python.
The main goal of ODL is to facilitate the use of advanced mathematical tools for real-world problems, without having to implement all necessary parts from the bottom up. The focus of the toolbox is fast prototyping in inverse problems.[1][2][3] Its main audience is mathematicians and applied scientists in imaging. [4][5][6][7][8][9][excessive citations]
History
ODL was initially developed at KTH Royal Institute of Technology as part of a research project funded by Swedish Foundation for Strategic Research.[1][10] It is currently being developed at [2]

- Technical University of Berlin

Solving inverse problems
A real-world domain is converted into a software with a forward model. Bringing a forward model into a goal state by finding the input values is called an inverse problem.[5] The Operator Discretization Library was developed on top of the TensorFlow library[11] to solve these inverse problems with state space sampling. Unfortunately, state space sampling[12] and other optimization techniques like gradient descent[13] take a large amount of execution time. An example problem will need up to 40 hours on a GTX 1080 TI graphics card until the Operator Discretization Library has detected a Computational human phantom.[14]
