Bottleneck Conditional Density Estimation

CoRR, 2016
We introduce a new framework for training deep generative models for high-dimensional conditional density estimation. The Bottleneck Conditional Density Estimator (BCDE) is a variant of the conditional variational autoencoder (CVAE) that employs layer(s) of stochastic variables as the bottleneck between the input $x$ and target $y$, where both are high-

Nonparametric Estimation of the Density Function of the Distribution of the Noise in CHARN Models

Mathematics, 2022
This work is concerned with multivariate conditional heteroscedastic autoregressive nonlinear (CHARN) models with an unknown conditional mean function, conditional variance matrix function and density function of the distribution of noise.

Density Conditions For Triangles In Multipartite Graphs

Combinatorica, 2006
We consider the problem of finding a large or dense triangle-free subgraph in a given graph $G$. In response to a question of P. Erd\H{o}s, we prove that, if the minimum degree of $G$ is at least $17|V(G)|/20 $, the largest triangle-free subgraphs are precisely the largest bipartite subgraphs in $G$. We investigate in particular the case where $G$ is a

Conditional Densities of Regular Languages

Electronic Notes in Theoretical Computer Science, 2005
AbstractWe define a density of a given language S in a given language L as an asymptotic probability that a randomly and uniformly chosen word of length n from L belongs to S. There are languages for which densities do not exist. We show that a problem of checking whether one regular language has a density in another regular language is decidable.

A probabilistic prediction of the next strong earthquake in the Acapulco-San Marcos segment, Mexico [PDF]

Geofísica Internacional, 2005
Conditional probabilities for recurrence times of large earthquakes are a reasonable and valid form for estimating the likelihood of future large earthquakes.

Asymptotic Normality of Conditional Density and Conditional Mode in the Functional Single Index Model

Ekonometria, 2021
The main objective of this paper is to investigate the nonparametric estimation of the conditional density of a scalar response variable Y, given the explanatory variable X taking value in a Hilbert space when the sample of observations is considered as ...

A New Efficient Expression for the Conditional Expectation of the Blind Adaptive Deconvolution Problem Valid for the Entire Range ofSignal-to-Noise Ratio

Entropy, 2019
In the literature, we can find several blind adaptive deconvolution algorithms based on closed-form approximated expressions for the conditional expectation (the expectation of the source input given the equalized or deconvolutional output), involving ...

High-Resolution Crowd Density Maps Generation With Multi-Scale Fusion Conditional GAN

IEEE Access, 2020
The major challenges for density maps estimation and accurate counting stem from the large-scale variations, serious occlusions, and perspective distortions.
