Sum Product Flow: An Easy and Extensible Library for Sum-Product Networks
Work in Progress (*please don't merge yet*) - Added basic Edge/Node abstraction to compute the SPN layerwise - Added basic network architecture from TorchSPN to convert the spn structure to...
### What did you expect to happen? the example code does not execute ### What actually happened? the example code does not execute - ImportError: cannot import name 'from_numpy_matrix' from...
### Describe your request SPNs with some probabilities left undefined as parameters (e.g., p, 1-p). This would allow for the creation of SPNs where nodes are defined with parameters instead...
Make sure, that we are not regressing in terms of performance.
