Latent class analysis
Latent class analysis, also known as the latent class model, is a statistical method that sorts cases into unobserved subgroups, called latent classes, using categorical variables.
Latent Consistency Models
Latent Consistency Models (LCMs) are a few-step image generation method introduced in October 2023, letting Stable Diffusion generate images in 1 to 4 steps instead of 25 or more.
Latent diffusion model
A latent diffusion model is a generative model running diffusion denoising in an autoencoder's compressed latent space, introduced by Rombach and Ommer's group in Munich in December 2021.
Latent Dirichlet allocation
Latent Dirichlet allocation (LDA) is a generative probabilistic model in which each document is a mixture over latent topics, introduced by Blei, Ng, and Jordan in 2003 and the standard starting point for topic modeling.
Latent early syphilis
Latent early syphilis (early latent syphilis, ICD-11 1A61.5) is asymptomatic syphilis acquired within the past year, still infectious, diagnosed by serology plus history, and treated with a single 2.4-million-unit benzathine penicillin G dose.
Latent factor mixed model
A latent factor mixed model (LFMM) is a regression method that tests genetic loci for association with environmental variables while correcting for population structure through latent factors.
Latent growth curve model
A latent growth curve model is a structural equation modeling method that estimates change over time by treating each person's intercept and slope as latent variables.
Latent growth modeling
Latent growth modeling is a structural equation modeling technique that estimates how people change over time, treating each person's initial status and rate of change as latent variables.
Latent heat
Latent heat, also called specific latent heat, is the energy absorbed or released during a phase change like melting or boiling at constant temperature, measured in joules per kilogram.
Latent profile analysis
Latent profile analysis (LPA), also called finite mixture modeling, is a statistical method that classifies individuals into unobserved subgroups, called profiles, based on patterns in continuous variables.
Latent semantic analysis
Latent semantic analysis (LSA), also known as latent semantic indexing, is a natural language processing technique that represents words and documents as vectors derived from term co-occurrence, published in 1990.
Latent space model (network analysis)
A latent space model is a statistical model for network data representing each node as a point in an unobserved latent space, with edge probabilities determined by latent positions.
Latent transition analysis
Latent transition analysis, also known as latent Markov modeling, is a longitudinal statistical method that extends latent class analysis to estimate how individuals move between unobserved subgroups over time.
Latent tuberculosis
Latent tuberculosis (latent TB infection, inactive TB): live but inactive Mycobacterium tuberculosis bacteria without symptoms or contagiousness; up to 13 million U.S. cases, 5–10% lifetime progression risk, treatable with 3–4 month rifamycin regimens.
Latent variable model
A latent variable model is a probabilistic model in which each observed data point is paired with an unobserved variable, explaining high-dimensional data with few degrees of freedom.
Latent yaws
Latent yaws is the asymptomatic, serology-positive stage of Treponema pallidum subspecies pertenue infection, affecting up to six people per active case; treated with single-dose azithromycin under WHO eradication strategy.
