The Origin of Life: Models and Data. [PDF]
, 2017 A general framework for conventional models of the origin of life (OOL) is the specification of a 'privileged function.' A privileged function is an extant biological function that is excised from its biological context, elevated in importance over other

Framing Image Description as a Ranking Task: Data, Models and Evaluation Metrics
Journal of Artificial Intelligence Research, 2013 The ability to associate images with natural language sentences that describe what is depicted in them is a hallmark of image understanding, and a prerequisite for applications such as sentence-based image search.

Grain Surface Models and Data for Astrochemistry [PDF]
, 2017 The cross-disciplinary field of astrochemistry exists to understand the formation, destruction, and survival of molecules in astrophysical environments. Molecules in space are synthesized via a large variety of gas-phase reactions, and reactions on dust ...

Internet Archaeology, 2004 Databases are deeply embedded in archaeology, underpinning and supporting many aspects of the subject. However, as well as providing a means for storing, retrieving and modifying data, databases themselves must be a result of a detailed analysis and ...

Testing for Slope Heterogeneity Bias in Panel Data Models
Journal of business & economic statistics, 2018 Standard econometric methods can overlook individual heterogeneity in empirical work, generating inconsistent parameter estimates in panel data models.

Monotone Simultaneous Paths Embeddings in $\mathbb{R}^d$ [PDF]
Discrete Mathematics & Theoretical Computer Science, 2018 We study the following problem: Given $k$ paths that share the same vertex set, is there a simultaneous geometric embedding of these paths such that each individual drawing is monotone in some direction?

Factor copula models for item response data [PDF]
, 2015 Factor or conditional independence models based on copulas are proposed for multivariate discrete data such as item responses. The factor copula models have interpretations of latent maxima/minima (in comparison with latent means) and can lead to more ...

Agricultural Systems, 2017 Agricultural modeling has long suffered from fragmentation in model implementation. Many models are developed, there is much redundancy, models are often poorly coupled, model component re-use is rare, and it is frequently difficult to apply models to ...

Using Parsimonious Language Models on Web Data [PDF]
, 2008 In this paper we explore the use of parsimonious language models for web retrieval. These models are smaller thus more efficient than the standard language models and are therefore well suited for large-scale web retrieval.

Fixed Effects Estimation of Large-TPanel Data Models
Annual Review of Economics, 2018 This article reviews recent advances in fixed effects estimation of panel data models for long panels, where the number of time periods is relatively large.
