Handwritten documents can be characterized by their content or by the shape of the written characters. We focus on the problem of comparing a person's handwriting to a document of unknown provenance using the shape of the writing, as is don...
Knot selection in sparse Gaussian processes with a variational objective function [0.03%]
稀疏高斯过程中具有变分目标函数的结点选择

Sparse, knot-based Gaussian processes have enjoyed considerable success as scalable approximations of full Gaussian processes. Certain sparse models can be derived through specific variational approximations to the true posterior, and knots...
An algorithm to compare two-dimensional footwear outsole images using maximum cliques and speeded-up robust feature [0.03%]
基于最大团和加速稳健特征的鞋印-outsole图像匹配算法研究

Footwear examiners are tasked with comparing an outsole impression (Q) left at a crime scene with an impression (K) from a database or from the suspect's shoe. We propose a method for comparing two shoe outsole impressions that relies on ro...
Nonlinear variable selection with continuous outcome: a fully nonparametric incremental forward stagewise approach [0.03%]

We present a method of variable selection for the sparse generalized additive model. The method doesn't assume any specific functional form, and can select from a large number of candidates. It takes the form of incremental forward stagewis...

Typically, when referring to a model-based classification, the mixture distribution approach is understood. In contrast, we revive the hard-classification model-based approach developed by Banfield and Raftery (1993) for which K-means is eq...
Whole-Volume Clustering of Time Series Data from Zebrafish Brain Calcium Images via Mixture Modeling [0.03%]

Calcium is a ubiquitous messenger in neural signaling events. An increasing number of techniques are enabling visualization of neurological activity in animal models via luminescent proteins that bind to calcium ions. These techniques gener...

Random forest (RF) missing data algorithms are an attractive approach for imputing missing data. They have the desirable properties of being able to handle mixed types of missing data, they are adaptive to interactions and nonlinearity, and...
Nonlinear Joint Latent Variable Models and Integrative Tumor Subtype Discovery [0.03%]

Integrative analysis has been used to identify clusters by integrating data of disparate types, such as deoxyribonucleic acid (DNA) copy number alterations and DNA methylation changes for discovering novel subtypes of tumors. Most existing ...
Hierarchical Models for Multiple, Rare Outcomes Using Massive Observational Healthcare Databases [0.03%]

Clinical trials often lack power to identify rare adverse drug events (ADEs) and therefore cannot address the threat rare ADEs pose, motivating the need for new ADE detection techniques. Emerging national patient claims and electronic healt...

Probabilistic forecasts are becoming more and more available. How should they be used and communicated? What are the obstacles to their use in practice? I review experience with five problems where probabilistic forecasting played an import...
