Adaptive Semiparametric Language Models [PDF]

open access: yesTransactions of the Association for Computational Linguistics, 2021
We present a language model that combines a large parametric neural network (i.e., a transformer) with a non-parametric episodic memory component in an integrated architecture.

Determining factors associated with the number of oocytes with appropriate morphology in infertile women: A cross-sectional study [PDF]

open access: yesInternational Journal of Reproductive BioMedicine
Background: Infertility affects millions of couples worldwide. The number of morphologically normal oocytes (MNO) is a key determinant of assisted reproductive technology success. Accurate identification of influencing factors is limited by excess zeros

Combining semiparametric and machine learning approaches for short-term prediction of satellite clock bias [PDF]

open access: yesScientific Reports
Accurate modeling of satellite clock bias (SCB) is critical for enhancing high-precision positioning capabilities. Existing approaches, such as semiparametric adjustment models and neural networks, address the nonlinearity and non-stationarity of SCB ...

Semiparametric Duration Models [PDF]

open access: yesJournal of Business & Economic Statistics, 2004
In this article we consider semiparametric duration models and efficient estimation of the parameters in a non-iid environment. In contrast to classical time series models where innovations are assumed to be iid we show that in, for example, the often-used autoregressive conditional duration (ACD) model, the assumption of independent innovations is too

Semiparametric Additive Beta Regression Models

open access: yesRevstat Statistical Journal, 2021
In this paper, we study a semiparametric additive beta regression model using a parameterization based on the mean and a dispersion parameter. This model is useful for situations where the response variable is continuous and restricted to the unit ...

A Semiparametric Model for VQTL Mapping [PDF]

open access: yesBiometrics, 2016
Summary Quantitative trait locus analysis has been used as an important tool to identify markers where the phenotype or quantitative trait is linked with the genotype. Most existing tests for single locus association with quantitative traits aim at the detection of the mean differences across genotypic groups.

Semiparametric hierarchical model with heteroscedasticity [PDF]

open access: yesStatistics and Its Interface, 2017
Recent work on hierarchical data analysis mainly focuses on the multilevel structure of the mean response. Little research for hierarchical heteroscedasticity was done in the literature. In this paper, we propose a class of hierarchical models with heteroscedasticity and then investigate the semi-parametric statistical inferences.

An introduction to pspatreg

open access: yesREGION, 2022
This article introduces a new R package (pspatreg) for the estimation of semiparametric spatial autoregressive models. pspatreg fits penalized spline semiparametric spatial autoregressive models via Restricted Maximum Likelihood or Maximum Likelihood ...
