Read e-book online An Inductive Logic Programming Approach to Statistical PDF

By K. Kersting

During this booklet, the writer Kristian Kersting has made an attack on one of many toughest integration difficulties on the middle of man-made Intelligence study. This comprises taking 3 disparate significant components of analysis and making an attempt a fusion between them. the 3 components are: common sense Programming, Uncertainty Reasoning and laptop studying. almost all these is a huge sub-area of study with its personal linked foreign examine meetings. Having taken on this sort of Herculean activity, Kersting has produced a chain of effects that are now on the middle of a newly rising region: Probabilistic Inductive good judgment Programming. the recent sector is heavily tied to, although strictly subsumes, a brand new box often called 'Statistical Relational studying' which has within the previous couple of years won significant prominence within the American man made Intelligence learn group. inside this ebook, the writer makes a number of significant contributions, together with the creation of a chain of definitions which circumscribe the hot region shaped via extending Inductive good judgment Programming to the case within which clauses are annotated with likelihood values. additionally, Kersting investigates the strategy of studying from proofs and the problem of upgrading Fisher Kernels to Relational Fisher Kernels.

Sample text

A model that is not sufficiently complex can fail to fully detect the underlying rule of a complicated data set, leading to underfitting. A model that is too complex may fit the noise, not just the underlying rule, leading to overfitting and, for instance, wild predictions. §2 Probabilistic Inductive Logic Programming 20 Refinement operators can also be used to encode a language bias, since they can be restricted to generate only a subset of the language LH . For instance, refinement operators can easily be modified to generate only constant-free and function-free clauses.

2 Inductive Logic Programming (ILP) and its Settings 19 Refinement operators ρ on clauses can straightforwardly be extended to logic programs H by defining ρ(H) = H \ {c} ∪ {ρ(c)}. Based on refinement operators, ILP systems traverse the hypothesis space H, which consists of all logic programs over LH , according to some generality notation. 15 (More–General–Than Relation) A hypothesis G is more general than a hypothesis S if all examples covered by S are also covered by G. ◦ Several generality frameworks have been proposed including inverse implication, inverse resolution and inverse entailment.

2 Probabilistic Inductive Logic Programming 26 The probability of a failure is zero and, consequently, failures are never observable. , the probabilities of such derivations are greater zero. 2. , P (Neg|H, B) = 0 . 4. Rex is a male person; he cannot be the daughter of ann. Thus, daughter(rex, ann) was listed as a negative example. ◦ Negative examples conflict with the usual view on learning examples in statistical learning. In statistical learning, we seek to find that hypothesis H ∗ , which is most likely given the learning examples: H ∗ = arg max P (H|E) = arg max H H P (E|H) · P (F ) P (E) with P (E) > 0 .
