Linear separator - A linear separator is a decision boundary defined by a weighted sum of features plus an offset.
Linear shift-invariant (LSI) filter - A linear shift-invariant filter, or LSI filter, preserves superposition and responds the same way when an input pattern is shifted in space.
Linear temporal logic - Linear temporal logic, or LTL, is a formal language for describing how conditions should hold along a sequence of system states.
Linear transformation - In the supplied statistics glossary, a linear transformation changes a numerical variable by multiplying it by a constant and adding a constant: Y = a + bX.
Linear trend estimation - Linear trend estimation fits a straight-line change over time to observed data, commonly using a model such as Yt = a + bt + error.
Linearity of regression - Linearity of regression is the assumption that the systematic mean relationship is adequately represented by the specified linear form.

Linguistic Linked Open Data - Linguistic Linked Open Data, or LLOD, is an approach and community movement for publishing and connecting language resources using linked-data principles...
Linguistic value - A linguistic value is a word or phrase used as a value of a linguistic variable, such as low, moderate or high for workload.
Link rot - Link rot is the loss of access to a resource through a previously useful web link, often because the resource has been removed, moved without a suitable...
Linkage constraints - Linkage constraints are restrictions imposed by the physical connections among the links and joints of a mechanism.

Linked data - Linked data is an approach to publishing and connecting structured data using Web identifiers and explicit relationships.
Linking Bias - Linking bias describes systematic differences in the networks inferred from people's recorded connections, interactions or activity.
Lipschitz continuity - Lipschitz continuity is a bound on how quickly a function's output can change relative to its input.
Liquid event - A liquid event is an event type or temporal property that, when true throughout an interval, is also true throughout its subintervals.
Liquid State Machine Network - A liquid state machine network is a reservoir-computing architecture that transforms a time-varying input into changing internal activity, commonly in a...

LLM-as-a-judge - LLM-as-a-judge is an evaluation method in which a large language model assesses an answer, conversation, or other output using specified criteria.
LLM evaluations (evals) - LLM evaluations, often shortened to evals, are structured tests used to measure how a large language model or a system built around it performs.
