Toward more scalable structured models
… biology and physical sciences, training such models is known to require significant amounts of data. One possible reason is that the structural properties of the data and problem are not modeled explicitly. Effectively exploiting the structure can help build more efficient and performing …

In-sample forecasting: structured models and reserving
… as a non-parametric estimation approach in a structured model setting. The forecast of future claims is done without the use of exposure information, i.e., without knowledge about the number of underwritten policies. New statistical estimation techniques and properties are derived which are …

Learning structured models for robotic manipulation of deformable objects
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-10-19 without embargo terms

Effects of cannibalism, maternal age and varying fish selectivity in age structured models of deep water hake populations
An Age Structured Model (ASM) was develop in which dynamic and density-dependent cannibalism was included as a top-down control on a modeled population of M. paradoxus which used spawner biomass and maternal based recruitment. The ASM was used to evaluate the effects cannibalism had on age …

Large Scale Machine Learning in Biology
… informative patterns and clinically predictive models using this data. Motivated by an existing graph partitioning framework, we first derive relationships between optimizing the regularized min-cut cost function used in spectral clustering and the relevance information as defined in the …

The impact of bias in length frequency data on an age structured fisheries stock assessment model
Statistical age-structured models are widely used in fisheries stock assessment. These models have been become increasingly complex over recent decades, allowing them to incorporate a larger variety of fisheries data. These typically include information regarding annual fishery yields, indices of …

Implementation of symbolic model checking for probabilistic systems
… used to perform probabilistic analysis of large, structured models with more than 7.5 billion states, way out of the reach of conventional, explicit techniques, based on sparse matrices. We also propose a novel, hybrid approach, combining features of both symbolic and explicit implementations and …

Deep learning benchmarks on L1000 gene expression data
… structure, but the development of such models is hampered by the lack of an empirical methodological foundation, including published benchmarks and well characterized baselines. In this work, we lay that foundation by profiling a battery of classifiers against newly defined biologically …

An Application of Reliability Engineering Concepts to the Analysis of the Accounting Control Systems
… accounting have acknowledged the need for structured models for the analysis and evaluation of the accounting control systems. This study presents a framework for a decision support system (based on reliability engineering concepts) for the assessment, design, and maintenance of the …

Study on fisheries resources with particular reference to red coral, spiny lobster and other target demersal species in Sardinian Seas
… Sub-Area 11 (GSA 11), using data-rich, age-structured models (Extended Survivors Analysis, XSA). The results revealed a sustainably exploited stock, suggesting opportunities for adaptive management and compensation for effort restrictions under the Western Mediterranean Multiannual …

Faster and easier: cross-validation and model robustness checks
… model. For methods involving large and complex models, (1) is expensive in terms of user time, and (2) is expensive in terms of compute time. So CV, which requires (2), and robustness checks, which often require both (1) and (2), see little use in the large and complex models that need them the …

Heterogeneous reservoirs in the marine carbon cycle
… the carbon cycle can be packaged in terms of age structured models and their accompanying age and rate distributions. We further relate the moments of the rate distributions to bulk reservoir properties like average age and flux. Explicit relationships are then derived for the specific case of a …

Convex optimization methods for graphs and statistical modeling
… among a large number of interacting entities. Models based on graphs form one major thrust in this thesis, as graphs often provide a concise representation of the interactions among a large set of variables. A second major emphasis of this thesis are classes of structured models that satisfy …

Structuring process models
… employing scientific methods. Usually, process models are formalized as directed graphs, with nodes representing tasks and decisions, and directed arcs describing temporal constraints between the nodes. Common process definition languages, such as Business Process Model and Notation (BPMN) and …

Characterizing early growth and reproduction of Blueline Tilefish (<i>Caulolatilus microps</i>) to inform stock assessments
… found in the past persisted, and preferred age-structured models were not used. Additionally, maturity was estimated from a meta-analysis of other species with similar life histories. Research recommendations from independent peer reviewers thus included improving age determination as well as …

Bayesian population dynamics modeling to guide population restoration and recovery of endangered mussels in the Clinch River, Tennessee and Virginia
… A Bayesian approach was used to analyze the age-structured models and a Bayesian model averaging approach was applied to average the results by weighting each model using the deviance information criterion (DIC). A risk assessment was conducted to evaluate alternative restoration strategies for …
