Self-adaptive evolution of model structures and parameters / by Jason John Bobbin.
… thesis proposes a new self-adaptive, symbiotic model evolution framework SASME. SASME is described generally and then applied to the specific task of evolving rule sets with explicit default hierarchies for learning problems. Experiments are conducted on the SASME framework to establish the …

Using a bio-inspired model to understand the evolution of the remora adhesive disk
… challenging wetted conditions. A remarkable evolutionary advancement is found in the family of echenidae, colloquially known as the remora. In particular, the remora fishes have the ability to attach to wet, compliant bodies under high shear conditions for extended periods of time. This …

Wind-driven circulation on a shallow, stratified shelf
… 1988-89 is carried out through a combination of modeling, scale estimates, and data analysis. We develop a prognostic one-dimensional mixed layer model which is coupled to a thermodynamic ice model. Our model contains a representation of the lowest order boundary layer dynamics and adjustable …

Testing the effect of varying environments on the speed of evolution
… Computer scientists use simulation of natural evolution to create algorithms and data structures to solve complex optimization problems. This field of study is called evolutionary computation. In evolutionary computation, the speed of evolution is defined as the number of generations needed for …

Population boundaries and gravitational-wave templates for evolving white dwarf binaries
… inspiraling and mass-transfer stages of their evolution. Theoretical constraints on the properties of the white dwarf stars allow us to map out the DWD trajectories in the gravitational-wave amplitude-frequency domain and to identify population boundaries that define distinct sub-domains where …

A Radiative Model for the Study of the Feedback Mechanism between Photolytic Aerosols and Solar Radiation
Since the early 70's chemistry and transport models (ChTMs) have been proposed and improved. Tropospheric ChTMs for trace species are detailed numerical formulations intended to represent the atmospheric system as a whole, accounting for all the individual processes and phenomena that influence …

Evolving Intentions: Support for Modeling and Reasoning about Requirements that Change over Time
In early-phase requirements engineering, modeling stakeholder goals and intentions helps stakeholders understand the problem context and evaluate tradeoffs, by exploring possible "what if" questions. Prior research allows modelers to make evaluation assignments to desired goals and generate …

Modeling convection in the Greenland Sea
… 1988-89 is carried out through a combination of modeling, scale estimates, and data analysis. We develop a prognostic one-dimensional mixed layer model which is coupled to a thermodynamic ice model. Our model contains a representation of the lowest order boundary layer dynamics and adjustable …

Efficient Reasoning with Constrained Goal Models
GOAL models have been widely used in Computer Science to represent software requirements, business objectives, and design qualities. Existing goal modelling techniques, however, have shown limitations of expressiveness and/or tractability in coping with complex real-world problems. In this work, we …

Deep learning with very few and no labels
… training samples to learn its huge network model. Labeling a large dataset is labor-intensive, time-consuming, and sometimes requiring expert knowledge. In this research, we study the following important question: how to train deep neural networks with very few or even no labeled samples? …

Structural Model Discovery in Temporal Event Data Streams
… construction and modification of behavior models. Our focus is to introduce the research area of behavior analysis, the challenges faced by this field, current approaches available, and present a new analysis approach: Interactive Relevance Search and Modeling (IRSM). More intelligent ways …

A cross-scale model for the evolution of influenza within a single season
… thesis we develop a mathematical cross-scale model for the evolution of influenza within a single season. We model evolution as the emergence and spread of a mutant strain in a population that is already invaded by a parent resident strain. This allows us to investigate both the emergence …

From a slave to a critical-thinker-artistic-writer: Emancipating a professional's anthill using action research professional practice with information systems professionals as the crux: Gnothe se auton non, j regrette rien die lichtung and all the world's a stage
… writer. The text at the centre reads "my rich model evolution during this thesis." On rereading the text, I wonder if it is referring to my own evolution during the research, which could be described as "rich model," or the evolution of the rich model that encapsulates, and in one sense is, the …

Fully nonlinear interfacial waves in a bounded two-fluid system
… the derivation of two-and three-dimensional model evolution equations using long-wave asymptotics and the ensuing analysis and computation of these models. In addition, we derive the appropriate Birkhoff-Rott integro-differential equation for two-phase inviscid flows in channels of arbitrary …
