Random Probabilistic Circuits

Usage

To run the algorithms and their grid search check the scripts in the bin/ folder.
To learn a default ensemble from the training set portion of the nltcs data you can call:

ipython -- bin/expc_exp.py nltcs

To get an overview of the possible parameters use ipython -- bin/expc_exp.py -h :

  -dim ENSEMBLE_DIMENSION [ENSEMBLE_DIMENSION ...], --ensemble-dimension ENSEMBLE_DIMENSION [ENSEMBLE_DIMENSION ...]
                        EXPC dimension
  -sd STR_DEC_LEVEL [STR_DEC_LEVEL ...], --str-dec-level STR_DEC_LEVEL [STR_DEC_LEVEL ...]
                        0 for no-SD; 1 for no-SD EXPC with SD XPCs;
                        2 for SD EXPC
  -det DETERMINISM [DETERMINISM ...], --determinism DETERMINISM [DETERMINISM ...]
                        0 for no-determinism; 1 for determinism
  -m MIN_PARTITION_INSTANCES [MIN_PARTITION_INSTANCES ...], --min-partition-instances MIN_PARTITION_INSTANCES [MIN_PARTITION_INSTANCES ...]
                        Minimum number of instances per partition
  -l CONJUNCTION_LENGTH [CONJUNCTION_LENGTH ...], --conjunction-length CONJUNCTION_LENGTH [CONJUNCTION_LENGTH ...]
                        Conjunction length
  -a ARITY [ARITY ...], --arity ARITY [ARITY ...]
                        Maximum number of sum nodes children
  -p MAX_PARTITIONS [MAX_PARTITIONS ...], --max-partitions MAX_PARTITIONS [MAX_PARTITIONS ...]
                        Maximum number of leaf partitions
  -p SMOOTHING [SMOOTHING ...], --smoothing SMOOTHING [SMOOTHING ...]
                        Smoothing parameter alpha
  -o [OUTPUT], --output [OUTPUT]
                        Output dir path

To run a grid search you can do:

ipython -- bin/expc_exp.py nltcs -dim 10 20 -sd 0 1 2 -det 0 1 -m 256 -l 3 -a 3 -p 200
