Deriving Production Rules for Constraint Maintenance
, 1990
"... . Traditionally, integrity constraints in database systems are maintained either by rolling back any transaction that produces an inconsistent state or by disallowing or modifying operations that may produce an inconsistent state. An alternative approach is to provide automatic "repair " o ..."

; of inconsistent states using production rules. For each constraint, a production rule is used to detect constraint violation and to initiate database operations that restore consistency. We describe an SQL-based language for defining integrity constraints and a framework for translating these constraints
Deriving Production Rules for Incremental View Maintenance
- In Proceedings of the Seventeenth International Conference on Very Large Data Bases
, 1991
"... . It is widely recognized that production rules in database systems can be used to automatically maintain derived data such as views. However, writing a correct set of rules for efficiently maintaining a given view can be a difficult and ad-hoc process. We provide a facility whereby a user defines a ..."

Set-Oriented Production Rules in Relational Database Systems
, 1990
"... We propose incorporating a production rules facility into a relational database system. Such a facility allows definition of database operations that are automatically executed whenever certain conditions are met. In keeping with the set-oriented approach of relational data manipulation languages, o ..."

Generating Production Rules From Decision Trees
- PROCEEDINGS OF THE 10TH INTERNATIONAL JOINT CONFERENCE ON ARTIFICIAL INTELLIGENCE - VOLUME 1
, 1987
"... Many inductive knowledge acquisition algorithms generate classifiers in the form of decision trees. This paper describes a technique for transforming such trees to small sets of production rules, a common formalism for expressing knowledge in expert systems. The method makes use of the training set ..."

The CN2 Induction Algorithm
- MACHINE LEARNING
, 1989
"... Systems for inducing concept descriptions from examples are valuable tools for assisting in the task of knowledge acquisition for expert systems. This paper presents a description and empirical evaluation of a new induction system, cn2, designed for the efficient induction of simple, comprehensib ..."

Factor Graphs and the Sum-Product Algorithm
- IEEE TRANSACTIONS ON INFORMATION THEORY
, 1998
"... A factor graph is a bipartite graph that expresses how a "global" function of many variables factors into a product of "local" functions. Factor graphs subsume many other graphical models including Bayesian networks, Markov random fields, and Tanner graphs. Following one simple c ..."

A wide variety of algorithms developed in artificial intelligence, signal processing, and digital communications can
Training Products of Experts by Minimizing Contrastive Divergence
, 2002
"... It is possible to combine multiple latent-variable models of the same data by multiplying their probability distributions together and then renormalizing. This way of combining individual “expert ” models makes it hard to generate samples from the combined model but easy to infer the values of the l ..."

A product of experts (PoE) is therefore an interesting candidate for a perceptual system in which rapid inference is vital and generation
An integrated theory of the mind
- PSYCHOLOGICAL REVIEW
, 2004
"... There has been a proliferation of proposed mental modules in an attempt to account for different cognitive functions but so far there has been no successful account of their integration. ACT-R (Anderson & Lebiere, 1998) has evolved into a theory that consists of multiple modules but also explain ..."

Subsymbolic processes serve to guide the selection of rules to fire as well as the internal operations
