There appears to me to be a difficulty in this conclusion: that
happenings which depend upon an infinite number of cases cannot be
determined by a finite number of experiments; indeed nature has her
own habits, born from the return of causes, but only 'in general'. And
so, who will say whether a subsequent experiment will not stray
somewhat from the rule of all the preceding experiments, because of
the very mutabilities of things? [Letter from Leibniz to Bernoulli, 3
December 1703. Quoted in: Cussens, Probability and Statistics in Antognazza (ed.) The Oxford Handbook of Leibniz, OUP, 2018.]

Inductive Logic Programming for Software Agents:
Algorithms and Implementations
Software
 GOBNILP software for exact Bayesian network learning
 gPy is a collection of
Python modules for manipulating discrete hierarchical models
(including Bayesian nets). It was used to support the
teaching of Algorithms for Graphical
Models.
 The
MCMCMS (Markov chain Monte Carlo over Model Structures)
system
uses Stochastic Logic Programs (SLPs) to define priors for
Bayesian inference. The code was written by
Nicos Angelopoulos.

Pepl
is an implementation of the FailureAdjusted Maximisation
(FAM) algorithm.This is an instance of the EM algorithm which
produces maximum likelihood estimates for the parameters of
SLPs. The code was written by Nicos Angelopoulos.

Aaron Bate, a final year student in this department, has
produced software for animating the construction of Prolog
proof trees (the software draws a graphical representation
of the proof tree). It uses Sicstus Prolog and Tcl/Tk. You can download the software as a gzipped
tar file. I have included a simple Prolog SLP
interpreter which allows you to sample from a distribution
over proof trees and where each proof tree determines an
acyclic digraph (the structural element of a Bayesian
net). See the file slp_readme in the distribution
for an explanation.
