We investigate paid endorsement as a crowd-sourcing social advertising mechanism that allows advertisers to bypass publishers (e.g., Facebook) and recruit individual endorsers of their own choice at affordable prices. Specifically, we investigate (i) how incentives affect endorsers’ participation and effectiveness, (ii) what types of endorsers are most effective in generating online engagement ...

Recently many promising results have been shown on face recognition related problems. However, ageinvariant face recognition and retrieval remains a challenge. Inspired by the observation that age variation is a nonlinear but smooth transform and the ability of auto-encoder network to learn latent representations from inputs, in this paper, we propose a new neural network model called coupled a...

In many vision problems, the observed data lies in a nonlinear manifold in a high-dimensional space. This paper presents a generic modelling scheme to characterize the nonlinear structure of the manifold and to learn its multimodal distribution. Our approach represents the data as a linear combination of parameterized local components, where the statistics of the component parameterization desc...

The regulation and responses of genes involve complex systems of relationships between genes, proteins, DNA, and a host of other molecules that are involved in every aspect of cellular activity. I present algorithms that learn expressive computational models of cis-regulatory modules (CRMs) and gene-regulatory networks. These models are expressive because they are able to represent key aspects ...

Abstract We consider energy‐dispersive x‐ray fluorescence (XRF) applications where the fundamental parameters method is impractical such as when instrument are unavailable. For example, on a mining shovel or conveyor belt, rocks constantly moving (leading to varying angles of incidence and distances) there may be other factors not accounted for (like dust). Neural networks do require but traini...

A profile is a relationship between a response variable and one or more independent variables being controlled during the time. Process Capability Indices (PCI) are measured to evaluate the performance of processes in producing conforming products. Despite frequent applications of profile and a variety of available methods to monitor its different types, little researches have been carried out ...
