Inference is the act or process of deriving logical conclusions from premises known or assumed to be true. The conclusion drawn is also called an idiomatic. The laws of valid inference are studied in the field of logic.

Inference is the act or process of deriving logical conclusions from premises known or assumed to be true. The conclusion drawn is also called an idiomatic. The laws of valid inference are studied in the field of logic.

Or inference can be defined in another way. Inference is the non-logical, but rational, means, through observation of patterns of facts, to indirectly see new meanings and contexts for understanding. Of particular use to this application of inference are anomalies and symbols. Inference, in this sense, does not draw conclusions but opens new paths for inquiry. In this definition of inference, there are two types of inference: inductive inference and deductive inference. Unlike the definition of inference in the first paragraph above, meaning of word meanings are not tested but meaningful relationships are articulated.

Human inference (i.e. how humans draw conclusions) is traditionally studied within the field of cognitive psychology; researchers develop automated inference systems to emulate human inference. Statistical inference allows for inference from quantitative data.

Type intersections using any

From https://github.com/Microsoft/TypeScript/pull/3622: Supertype collapsing: A & B is equivalent to A if B is a supertype of A. However: type a = string & any; // Resolves to any, not string!? This intersection resolves to any. Isn't 'any' a…

Type inference in sequence expressions in F#

I think I do not quite understand how F# infers types in sequence expressions and why types are not correctly recognized even if I specify the type of the elements directly from "seq". In the following F# code we have a base class A and two derived…

What does a 'tractable' distribution mean?

For example, in generative adversarial network, we often hear that inference is easy because the conditional distribution of x given latent variable z is 'tractable'. Also, I read somewhere that Boltzmann machine and variational autoencoder is used…
