理解latent variable，即潜变量，是统计学领域的一个核心概念。潜变量是无法直接观测到的变量，它们通过数学模型从可观察变量中推导得出。在统计分析中，潜变量模型将观察变量解释为潜变量的函数。这些模型在心理学、经济学、社会学等多个学科中广泛应用。在心理学中，例如，广义智力是一个潜变量，通过IQ测...
测量Latent Variable的最简单方法是找到一个被认为是Latent Variable的足够精确测量值的单个观测变量。例如...
然而,由此生成的latent variable缺乏高级语义信息和其它latent space属性(例如插值、特征解耦)。本文介绍了一种名为Diffusion Autoencoders的表征学习方法,通过设计一种特殊的conditional DDIM实现表征的可解码性。 1 方法介绍 Diffusion Autoencoders是一个特殊的Conditional DDIM模型,由semantic encoder、stochastic encoder和...
In this study, a new post‐transformation method, called post‐transformation of the Latent Variable space (ptLV), is introduced. The method generates a latent space isomorphic to that discovered by PLS2 where the non﹑redictive data variation is separated from the predictive one. It works on...

隐性变量法（Latent variable approach, LV）是一种统计分析方法，它将难以直接观测的变量称为隐性变量。这种方法的核心在于，通过引入这些隐性变量，我们可以更好地理解和估计那些无法直接测量的经济或社会指标，如全要素生产率。全要素生产率（Total Factor Productivity, TFP）是一种衡量经济整体效率的指标...

A Latent Variable Model refers to a type of model that incorporates hidden variables to improve prediction accuracy, account for measurement error, and accurately represent the joint distribution of observed variables and their effects on each other. While they have advantages over nonlatent variable ...
Since the dimensionality of hands state space is too high,we employ a hierarchical Gaussian process latent variable model (GPLVM) to simultaneously learn the hierarchical latent space of hands motion and the nonlinear mapping from the hierarchical latent space to the state space of human hands. Nonl...
