Re: [GRASS-user] bayesian belief network analysis (was r.binfer)
Hi Donovan, If you know how to put together some Python code, you could have a look at PyMC3: https://docs.pymc.io/ That can be basically used like scikit-learn in r.learn.ml. You load GRASS data into a numpy array with e.g. r.what, r.stats, v.db.select, or using pygrass (e.g. reading entire raster maps with raster2numpy) and create training and test data that that you feed into a model... There have been some efforts to move to TensorFlow as backend in PyMC, but that seems to be abandoned and PyMC devs are now continuing with JAX (https://pymc-devs.medium.com/the-future-of-pymc3-or-theano-is-dead-long-live-theano-d8005f8a0e9b).

[GRASS-user] bayesian belief network analysis (was r.binfer)
Evening, I'm attempting to analyze a set of layers (slope, aspect, vegetation, soil, etc) that have been coded/scored based on expert opinion to output a probability/suitability map. I'm looking to apply a bayesian belief network [1] and i've got the raster layers ready for the inputs and coded like seen in this figure [2]. There was a grass4 module called r.binfer [3] that did this and I can't seem to find it with GRASS 78 - deprecated or replaced? Searches lead me to either r.regression.multi [4] or r.learn.ml [5] but i'm not sure where to start with these to get a BBN processed thru them.
