This is the code release of the information maximising neural network code used in the paper Automatic physical inference with information maxmising neural networks (arXiv:1802.03537). It contains all the machinery to create the data in the paper, and can be used to rerun any analysis. The network itself is complete for use with any external data, although the protocols for use must be of the form used in the paper. Citing arXiv:1802.03537 is a condition of use of the code for any publication.
