Variational inference
| Глоссарий по искусственному интеллекту |
Variational inference is an approximation technique that can be used when exact or monte carlo computation is infeasible. in the case of a network model with hidden variables h and observed (visible) variables v, a variation solution would approximate pr(h|v) with some tractable q(h|v), where q(h|v) minimizes some distance measure (e.g., relative entropy) with respect to pr(h|v). see also: helmholtz machine, markov chain monte carlo methods.

Inference, английский
- N когн. инференция, умозаключение2 conversational ~ конверсационное умозаклю- чение
- Логический вывод; следствие; умозаключение inference-based algorithm алгоритм, основанный на логическом выводе
- Вывод, заключение
- Refers to the processes used to draw conclusions from facts and other premises or conclusions.
Inference attack, английский
This usually refers to a database when an authorised entity is able to infer sensitive information from authorised query results and prevailing common knowledge. for example, an authorised user accessing a database might be able to identify an entity based on a combination of criteria, such as age, gender, date of birth and postal code.
Inference capacity, английский
Мощность логического вывода

Inference control, английский
Управление процессом логического вывода
Inference engine, английский
- Механизм логического вывода; метод логического вывода
- A term used for programs or subprograms that are specialized for the drawing of inferences. the term refers to that part of the program that performs the inference, rather that the data and premises that provides the knowledge.

Inference training, английский
A time-based assistant (tba) that parses emails and makes internal inferences based on them. inferences are used to allow the system to gain insight into a user’s mailbox based on user patterns. those inferences are then used to populate features for users, such as people view in outlook web app.
Inference training feeder, английский
A component that feeds data (such as mailbox messages) to the inference training assistant in batches. it controls performance by giving the inference training assistant a fixed amount of work to process at each interval.

Valuations, английский
Valuations are a generalization of the ideas of belief and probability functions, and provide a mapping from a set of outcomes over a frame of discernment to numeric values. a valuation has three properties. it supports combination, so that two valuations over the same frame can be combined. it allows projection (extensions and marginalizations) so that the frame of discernment can be changed. it meets certain requirements under which the combination and projection operations can be interchanged. a function meeting these conditions can be manipulated using the shafer-shenoy fusion and propagation algorithm. see also: shafer-shenoy architecture. vapnik-chervonenkis dimension the vapnik-chervonenkis dimension is a measure of the complexity of a concept in machine learning and is used to put lower bounds on the learnability of a concept. basically it describes the size of the largest set such that the concept class realizes all possible dichotomies of the sample. in other words, for a sample of size d, there are 2^d possible subsets of that sample. if every subset can be made positive for some example of the concept, then the concept class will have dichotomized the sample. see also: machine learning.
