A Robust Prediction Model for Species Distribution Using Bagging Ensembles with Deep Neural Networks

open access: yesRemote Sensing, 2021
Species distribution models have been used for various purposes, such as conserving species, discovering potential habitats, and obtaining evolutionary insights by predicting species occurrence. Many statistical and machine-learning-based approaches have

Dilation Bootstrap [PDF]

open access: yesSSRN Electronic Journal, 2011
We propose a methodology for constructing confidence regions with partially identified models of general form. The region is obtained by inverting a test of internal consistency of the econometric structure. We develop a dilation bootstrap methodology to deal with sampling uncertainty without reference to the hypothesized economic structure.

Normal-Bundle Bootstrap

open access: yesSIAM Journal on Mathematics of Data Science, 2021
Probabilistic models of data sets often exhibit salient geometric structure. Such a phenomenon is summed up in the manifold distribution hypothesis, and can be exploited in probabilistic learning. Here we present normal-bundle bootstrap (NBB), a method that generates new data which preserve the geometric structure of a given data set.

Using the Wild Bootstrap to Quantify Uncertainty in Mean Apparent Propagator MRI

open access: yesFrontiers in Neuroinformatics, 2019
Purpose: Estimation of uncertainty of MAP-MRI metrics is an important topic, for several reasons. Bootstrap derived uncertainty, such as the standard deviation, provides valuable information, and can be incorporated in MAP-MRI studies to provide more ...

Bootstrapping language acquisition [PDF]

open access: yesCognition, 2017
The semantic bootstrapping hypothesis proposes that children acquire their native language through exposure to sentences of the language paired with structured representations of their meaning, whose component substructures can be associated with words and syntactic structures used to express these concepts. The child's task is then to learn a language-

Time Series Regression Modelling: Replication, Estimation and Aggregation through Maximum Entropy

open access: yesEngineering Proceedings, 2023
In today’s world of large volumes of data, where the usual statistical estimation methods are commonly inefficient or, more often, impossible to use, aggregation methodologies have emerged as a solution for statistical inference.
