A  
Array [Ext] 
Standard Ocaml Array module with extended functionality.

B  
Bn 
The BN library reads, writes, and represents Bayesian networks
(BNs) and dependency networks (DNs) with conditional probability
distributions (CPDs) that are treestructured, tables, or arbitrary
sets of factors.

C  
Circuit 
The Circuit module provides an interface for working with
arithmetic circuits, so that learning and inference algorithms
can be built on top of this data structure/inference
representation.

D  
Data 
The Data module reads/writes data and schema files, which have a
common format throughout Libra

E  
Expat 
The Ocaml Expat library provides an interface to the Expat XML Parser.

Ext 
The ext library includes miscellaneous utility functions,
extensions to the OCaml standard library (including List and Array),
and two utility modules, Timer and Heap (priority queue implemented as
a binary heap).

F  
Factor [Mn] 
The Factor module is used for representing a factor in a factor graph.

H  
Hashset [Ext]  Hashset is similar to Hashtbl , but it stores only keys, and
the value is unit for all keys.

Hashtbl [Ext] 
Standard Ocaml Hashtbl module with extended functionality.

Heap [Ext] 
Simple implementation of an arraybased binary heap in OCaml.

L  
Lbfgs 
The lbfgs library acts as a simple wrapper to the C
LBFGS library written by Naoaki Okazaki.

List [Ext] 
Standard Ocaml List module with extended functionality.

M  
MP [Mn.Factor] 
Auxilary module for parsing factors.

Make [Ext.Hashtbl]  
MakeSeeded [Ext.Hashtbl]  
Mn 
The MN library reads, writes, and represents Markov networks with
factors represented as tables, trees, sets of features, or individual
features.

N  
NMap [Circuit]  
NSet [Circuit]  
P  
Pll 
The Pll module performs efficient computation of pseudolikelihood
and its gradient, given a Markov network represented as a set of
weighted conjunctive features.

S  
Spn 
SPN library provides data structure and methods for learning
sumproduct networks.

String [Ext]  
T  
Timer [Ext] 
Named timers.

V  
Varstate [Mn] 
Set of functions for indexing and iterating over the states of
sets of variables.
