Label

The ground‑truth category or value assigned to a data point used for supervised learning.

Label Smoothing

A technique that replaces hard labels with a mixture of the correct and incorrect labels to improve generalization.

Labeled Data

Data that has been annotated with correct outputs, used for supervised learning.

Lambda Architecture

A data‑processing architecture that handles massive quantities of data by using both batch and real‑time processing.

Large Language Model or LLM

A generative AI model trained on massive amounts of text to generate human‑like language and perform tasks such as summarization or conversation.

Large Language Model Seasoning

The way an AI tool’s output gradually takes on your individual flavor through sustained use, shaped by your prompting voice, your patterns, and the memory it keeps of how you work, so the same prompt produces a different result for you than for anyone else.

Large Reasoning Model (LRM)

A type of AI model designed to reason through problems step by step before producing an answer, trading speed for greater accuracy on complex tasks like strategy, analysis, and multi-step reasoning.

Latent Space

A compressed representation of input data learned by a model, capturing underlying features.

Layer Normalization

A technique that normalizes inputs across the features of a layer to stabilize learning.

Lead Scoring

Ranking leads based on their likelihood to convert using behavioural, demographic and firmographic data.

Learning Rate

A hyperparameter that controls how much a model’s weights are updated during training.

Linear Regression

A method for modelling the relationship between a dependent variable and one or more independent variables.

Linguistic Feature

Characteristics extracted from text data, such as syntax or sentiment, used in NLP models.

LLMO

The practice of structuring and publishing content so that large language models cite your brand in their responses, rather than ranking your pages in traditional search results.

Local Minimum

A solution that is better than neighbouring solutions but not necessarily the best overall; models aim to avoid getting stuck in local minima.

Look‑Alike Modeling

Identifying new prospects that resemble existing high‑value customers based on behavioural and demographic traits.

Loop Engineering

The practice of designing and tuning the iterative feedback cycles in agentic AI systems, where a generation step, an evaluation step, and a revision step repeat until output meets a defined quality threshold or a stop condition is reached.

Low‑Code Automation

Platforms that allow marketers to design automated workflows using minimal coding, often integrating AI for decision making.
