Exploring the potential of using remote sensing data to model agricultural systems in data-limited areas
… in isolated and rural areas, is often limited by the lack of reliable input data. This data scarcity increases uncertainties in model outputs. Nevertheless, some of these uncertainties can be mitigated by integrating remotely sensed data into the CMs. As such, increasing efforts are …

Life History and Management Methods for Blueline Tilefish (Caulolatilus microps) from the United States Mid-Atlantic Region
… for this region, necessitating the use of data-limited management methods to set restrictions for harvest of blueline tilefish in this area. This dissertation describes growth and reproductive characteristics of blueline tilefish caught off the coast of Virginia and explores improvements of …

Modeling species geographic distributions in aquatic ecosystems using a density-based clustering algorithm
… are generally developed and tested using data from terrestrial organisms, neglecting aquatic organisms in case studies. Both disease and aquatic systems are often data limited, and current modeling methods are often insufficient. There is, therefore, a need to develop data-driven models …

Multiclass Origin-Destination Estimation Using Multiple Data Types
… O-D estimation using various types of data. Limited memory BFGS method with bounded constraints is used for solving the upper level optimization, which is used to derive O-D table entries by minimizing the sum of squared differences between observations from different data sources and …

Interpretable neural networks via alignment and dpstribution Propagation
… Deep Neural Networks in various settings where data is limited or missing. Unlike data-rich tasks where neural networks have achieved human-level performance, other problems are naturally data limited where these models have fallen short of human level performance and where there is abundant …

Decentralized Data Markets
Acquiring access to massive amounts of data has become fundamental to state-of-the-art artificial intelligence systems. However, as data value increases, data owners have challenged current norms and practices of data acquisition. Data marketplaces have been promoted to fairly compensate data …

An in-depth analysis of guesser behavior
… each guesser when trained on varied real-world datasets and under different conditions (e.g., limited training data, limited number of guesses, or dissimilar training and testing data). We find that similarity of training to testing data is more important than dataset size, and that some …

An integrative predictive model for hospital acquired complications
… predicting the occurrence of HACs using clinical data limited to short periods following Intensive Care Unit (ICU) admission. In addition, we also identify several keystone features that demonstrate high predictive power HACs during certain time periods following patient admission. Based on our …

Life-History Characteristics and Fishery Dynamics of Red Drum (<i>Sciaenops ocellatus</i>), in the North-Central Gulf of Mexico
… their popularity, the stock is assessed using data limited approaches that necessitate accurate life history information. I estimated the year-specific and year-aggregated escapement rates for the Mississippi stock (years 2004 to 2015), which were sensitive to mortality estimation methods; …

SNAP vs. FSA: Competency-Based Numeracy Assessments Count
… the correlation of student cohort achievement data limited to the 2018/19 cohort of year six (grade 6) students in the Chilliwack School District. The study followed this cohort's achievement through completing the grade 7 FSA in the fall of 2019. There are 786 students represented in the …

Geomagnetic variations in the Northwest Atlantic : implications for the electrical resistivity of the oceanic lithosphere
… method. Models are shown to be severely data limited. Resolution is found to be poor in the upper 30-40 km of the lithosphere due to the lack of reliable data at periods shorter than 30 minutes. The uncertainty involved in estimating the magnetic field at the seasurface and the large …

Study on fisheries resources with particular reference to red coral, spiny lobster and other target demersal species in Sardinian Seas
… in Geographical 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 …

Subjetividade na interpretação dos dispositivos das sentenças judiciais e seus efeitos na perícia contábil em cumprimento de sentença
… by 68.20% (p < 0.05). The absence of direct cost data limited the analysis, but proxies such as new expert reports (5.88%) suggest indirect impacts. Grounded in legal and accounting communication theory and the Plain Language Movement, the study underscores the need for greater precision in …

Continual Learning for Engineering: Benchmarking and Exploring Strategies for 3D Engineering Problems
… intensive simulations paired with limited and evolving datasets. As new designs and constraints emerge, models must adapt to incoming data without frequent retraining, which is often infeasible due to the cost of generating engineering data. Continual learning (CL) offers a …

The characteristics of obesity and being overweight in children living in two Saskatchewan communities
There is limited study of the prevalence of childhood obesity and being overweight in 6 to 9 year old children living in Saskatchewan and Canada using the international standards and measured data. Limited data exists of the prevalence of obesity in rural and small urban communities. In 2000, a …

Applications of Probabilistic Machine Learning Models to Semiconductor Fabrication
… of semiconductor fabrication often results in data limited scenarios, as collecting large quantities of data can be infeasibly expensive. Because of this limitation, we investigate the use of probabilistic methods in a variety of semiconductor fabrication settings. These methods are often less …
