	Inference - Wikipedia, the free encyclopedia
		Inference is the act or process of drawing a conclusion based solely on what one already knows.
		Note that while an inference that leads from true premisses to a wrong conclusion is necessarily incorrect, true premises and a true conclusion do not necessarily imply that the inference was correct.
		But even if those facts were certain, the inference is of an inductive nature: perhaps you have often heard your neigbour at night, and the best explanation you have found is that he or she is an insomniac.

	Inference - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-08)
		To infer that X is to conclude that X is true; an inference is the conclusion drawn from a set of facts or circumstances.
		In reading or interacting with others, inferences can be, and often are, made about parts of the text where the meaning is implied but not explicit.
		Assessments of the ability to make inferences about written text are used to measure reading skill or listening skill.

	19. The Primitive Inference Procedures
		is the parameter to the primitive inference procedure.
		This primitive inference procedure applies the argument macete to the given sequent node, in the same way as macete-application, but with the following important difference: whenever the truth or falsehood of a convergence requirement cannot be determined by the simplifier, the assertion is posted as a additional subgoal to be proved.
		This primitive inference procedure simplifies the assertion of the given sequent with respect to the context of the sequent.

	Science Fair Projects - Inference
		Human inference (ie how humans draw conclusions) is traditionally studied within the field of cognitive psychology.
		Note that while an inference that leads from true premisses to a wrong conclusion is necessarily incorrect, true premisses and a true conclusion do not necessarily imply that the inference was correct.
		Although now somewhat past their heyday, AI systems for automated logical inference once were extremely popular research topics, and have know industrial applications under the form of expert systems.

	Inference procedure - Wikipedia, the free encyclopedia
		An inference procedure is a key component of the knowledge engineering process, sometimes known as abduction.
		After all preliminary information gathering and modeling is completed, queries are passed to the inference procedure to get answers.
		In this step, we let the inference procedure operate on the axioms and problem-specific facts to derive the information we are interested in knowing.

	Inference system - Patent 4803642
		An inference processing unit accesses the knowledge base, and extracts the strong attribute or the strong relation whose strength is presented by the weight, and obtains the interference result.

		It further outputs the inference result and executes the processing of a new matching on the basis of the matching result of pattern matching unit 13 and the calculation result from weight accumulator 15 when the pattern matching process is executed.

		The key to sound inference is to have the inference steps respect the semantics of the sentences they operate upon.
		Inference rules are used to make inferences without having to go through the process of building truth tables.
		An inference rule is sound if the conclusion is true in all cases where the premises are true.

	Introduction to Cyc Inferencing
		The major advantage to using CNF as an internal representation is that it greatly simplifies the conceptual scheme used in inferencing, because all axioms have a uniform structure.
		Backward inferencing--the type of inferencing initiated by an ASK operation--can be regarded as a search through a tree of nodes, where each node represents a CycL formula for which bindings are sought, and each link represents a transformation achieved by employing an assertion in the knowledge base.
		Thus, the primary issue to be addressed in designing an inference procedure is the algorithm to be used for searching the tree.

		Automated inference using FOL is harder than using PL because variables can take on potentially an infinite number of possible values from their domain.
		Resolution procedure uses a single rule of inference: the Resolution Rule (RR), which is a generalization of the same rule used in PL.
		Resolution procedure can be thought of as the bottom-up construction of a search tree, where the leaves are the clauses produced by KB and the negation of the goal.

	Defeasible Inference -- Inheritance
		And, because it is organized in his way, an inference procedure can take advantage of the fact that lower entities in the tree inherit the properties of their ancestors in the tree.
		Consequently, at this point the procedure has derived from this structure and its associated procedure that "jumbo is grey;" and the process terminates.
		Consequently, the procedure has failed to derive that "jumbo is white," and based on this failure derives that "jumbo is not white." This type of inference is known as Negation by Failure.

	Modularizing Inference in Large Causal Probabilistic Networks (Site not responding. Last check: 2007-10-08)
		The inference procedure is outlined and the principal data structure underlying the inference procedure are described.
		The modularization of the inference implies a need for transfer of information between modules, which is realized by establishing communication channels between modules.
		Modules are also used to perform inference by conditioning, a method that reduces storage requirements to a manageable size and thereby prepares the way for MUNINs migration to common PCs.

		In this project, two methods for making inferences about regression parameters will be studied: a semiparametric likelihood approach for observed ODS sample, and a pseudo-likelihood approach for further improving efficiency when the values of the outcome variable are known for the underlying cohort.
		The second project considers a new inference procedure for case-control studies in the presence of surrogate and missing/mismeasured exposure information.
		The third project concerns a new semiparametric likelihood based inference procedure that improves study efficiency by combining a superior measurement of exposure from the ODS sample and an inferior measurement from the underlying cohort population.

		Note that if this procedure terminates, then it describes a dag of inference certificates for inference steps with the right correspondence between parent premises and child conclusions.
		A procedure for "actively" certifying a proof would be similar, taking as a further argument a procedure for certifying inferences for which no acceptable certificate exists.
		At the other extreme, if the active procedure is employed with the stipulation that the only acceptable inference certificates are those it creates itself during that run, then its success would entail certifying anew every inference reachable from the root of the digraph.

	Conditional Analysis (Site not responding. Last check: 2007-10-08)
		The main point is that the statistical properties of a procedure are modified when that procedure is determined by a preliminary procedure.
		Even though a given model might be less amenable to direct solution of the inference problem at hand, it may contain certain parsimonious submodels which, when fitted, are easier to interpret (the case of no interactions).
		In the two-way methods investigated by Fabian, an initial inference for the interactions is used to reduce the dimensionality of the space of cell means, while the number of cell means, hence the number of confidence intervals to construct, remains the same.
