Using Deep Neural Nets in Writer Identification & Analysis
… document pages. CSE is designed to determine multiple attributes of an author such as authorship, gender, age and handedness. It achieves competitive performance compared to traditional page-level methods that typically rely on separate classifiers. While CTE is an exclusive classifier using a …

Assessment of small scale tallgrass prairie restoration in an urban environment
… prairies were successful and high in diversity. Multiple attributes of the restorations were examined as indicators of success including vegetation, the propagule bank and insects. However, not all attributes delivered equivocal results. This suggests that multiple measures should be used to …

On monitoring the attributes of a process
… are examined for monitoring processes with multiple attributes. Some relevant distribution theory is reviewed, and some new results are given. The distributions considered are multivariate versions of the binomial, Poisson, and chi-squared distributions, plus univariate and multivariate …

ENHANCING POLYMER INFORMATICS: A STUDY ON THE IMPACT OF FINGERPRINTING METHODS AND MACHINE LEARNING MODELS
… singletask learning models when predicting multiple attributes simultaneously. The neural network model shows the best performance in all evaluated attributes. Overall, PG fingerprinting consistently yielded lower root mean square error (RMSE) and normalized root mean square error (NRMSE) …

Steerable Alignment with Conditional Multiobjective Preference Optimization
… strategy that trains a user-steerable LLM along multiple attributes of text, such as helpfulness and humor. CMPO simulates the pareto front of multiple single-attribute preference-optimized models through structural plurality and finetuning with Direct Preference Optimzation (DPO), and allows …

Evolutionary market-based resource allocation in decentralised computational systems
… to heterogeneous buyer preferences over multiple attributes. The behaviour of the approach is studied both game theoretically and in simulation, where novel evolutionary market agents act on behalf of resource providing nodes to adaptively price their resources over time in response to …

Exploring the Role of Hydrogen in Decarbonizing Heavy Industry
… These processes rely on fossil fuels for multiple attributes and there is not another low carbon alternative fuel that has all of these characteristics. I find that in all regions, low carbon hydrogen production costs are currently more expensive than fossil fuels. High temperature heating …

Virginia-grown Cider: How do Cultivar and Fermentation Strategies affect Cider Chemistry, Flavor and Consumer Valuation?
… styles was larger for GoldRush. For sensory attributes, Harrison ciders produced high intensities for multiple attributes, but also higher variability. Multiple sensory descriptors displayed interaction effects as the fermentation method produced different results in different cultivars. This …

A domain independent method to assess system of system meta-architectures using domain specific fuzzy information
… The method describes how to elicit desired SoS attributes from stakeholders. Measures of the attributes depend on systems' participation and interfaces, that is, on the SoS architecture. The goal is to model a realizable SoS configuration, optimized over multiple attributes. Key attribute …

Protecting Sensitive Credential Content during Trust Negotiation
… A digital credential may contain sensitive attributes certifying characteristics about its owner. X.509v3, the most widely used certificate standard, includes support for certificate extensions that make it possible to bind multiple attributes to a public key contained in the certificate. …

Automatic Visualization of the Version history of a Software System in Three Dimensions
… when and where a change was made. In the case of multiple developers working on the same software system, version control systems also record which developer was responsible for the change. RCS, SCCS and CVS are examples of such version control systems, and they usually have a command-line …

Three essays on differentiated products and heterogeneous consumer preferences: the case of table eggs
… and advertised their products using relevant attributes. The increasing demand and supply of differentiated food products have raised questions regarding consumer preferences and producer strategies. This dissertation consists of three essays and empirically examines the egg market to shed …

Visual attention models for far-field scene analysis
… similarity measure that combines comparisons of multiple attributes -- such as size, position, and velocity -- in a principled manner so that only tracks that are spatially similar and have similar attributes at spatially corresponding points are grouped together. We group the tracks using …

Efficient processing of advanced structural queries in graph databases
… similarity queries. Moreover, graphs may possess multiple attributes on vertices, imposing additional challenges. Hence, indexing and processing methods for answering advanced structural queries are strongly in demand. The thesis studies three types of emerging structural queries in large-scale …

Two Marketing Essays: Evolution Of Attribute-Specific Preferences Through Consumer Learning And The Effect Of Gift Exchange On The Purchase Behavior
… offer many varieties of products with different attributes. In such cases, it is important to model consumer learning of attribute-specific preferences rather than simply modeling alternative-specific preferences in order to more accurately and parsimoniously describe consumer behavior. In this …

Abnormal Pattern Recognition in Spatial Data
… they may not accurately locate outliers when multiple outliers exist in a cluster and correlate with each other. Third, the existing algorithms tend to abstract spatial objects as isolated points and do not consider their geometrical and topological properties, which may lead to inexact …

Solving Single and Multiple Plant Sourcing Problems with a Multidimensional Knapsack Model
… model is extended to address outsourcing and multiple plants. This multi-plant model, also modeled as an MKP, enables the movement of parts from one plant to another and consideration of a company-wide objective function (as opposed to a single-plant objective function as in the insourcing …

Effective Methods of Semantic Analysis in Spatial Contexts
… and children, and bruteforce comparison of attributes. Most of these approaches suffer from the pitfalls of disparate data, often missing true relationships, failing to deal with inexact vocabularies, ignoring missing values, and poorly handling multiple attributes. In addition, the vast …

A unified decision analysis framework for robust system design evaluation in the face of uncertainty
… and decisions involving both uncertainty and multiple attributes. Application of the approach is illustrated by two hypothetical examples: bridge design and repairable equipment population system design.
