Information Lattice Learning as Probabilistic Graphical Model Structure Learning

Summary

Information lattice learning (ILL) learns interpretable rules of a signal by alternately projecting the signal onto a partition lattice and lifting selected rules back. When the signal is a probability mass function, the probabilistic rules learned by ILL admit a natural probabilistic graphical model (PGM) interpretation. A partition induces a deterministic quotient variable, and a rule is the marginal law of that variable. A rule set is a collection of marginal constraints over interpretable abstractions. General lifting is the feasible family of all joint distributions satisfying constraints, while special lifting chooses a maximum-ignorance reconstruction via an L2 uniformity principle related to maximum entropy.

Abstract:Information lattice learning (ILL) learns interpretable rules of a signal by alternately projecting the signal onto a partition lattice that encodes a hierarchy of abstractions and lifting selected rules back to the signal domain. When the signal is a probability mass function, we show the probabilistic rules learned by ILL admit a natural probabilistic graphical model (PGM) interpretation and develop this interpretation in detail. A partition in ILL induces a deterministic quotient variable, and a rule is the marginal law of that quotient variable. A rule set is therefore a collection of marginal constraints over interpretable abstractions. General lifting is the feasible family of all joint distributions satisfying those constraints, while special lifting chooses a maximum-ignorance reconstruction, implemented in ILL by an L2 uniformity principle closely related to maximum entropy. Under a Shannon-entropy lifting, the same constraints yield a log-linear factor graph whose factors are indexed by learned abstractions. The information lattice itself, however, is not a Bayesian network: its edges encode refinement and coarsening of abstractions, not conditional dependence. Thus ILL is best viewed as structure learning for interpretable constraint-based factor graphs over quotient variables. This view clarifies how ILL relates to graphical models and maximum entropy models, while suggesting new directions for inference, identifiability, and hybrid symbolic-probabilistic learning.

Key points

  • ILL learns interpretable rules from signals with a PGM interpretation for probability mass functions.
  • Partitions induce quotient variables; rules are marginal constraints; lifting reconstructs joint distributions.
  • ILL relates to maximum entropy models but is not a Bayesian network; it learns factor graph structures.
