Open-Set Object Based Data Association
… object detectors trained on a specific set of objects, such as the YCB objects, are used to provide input to the data association problem, which limits the scope of the system to environments that it has been trained on. With advancements in foundational models, we can extend this …

Spectrum Awareness: Deep Learning and Isolation Forest Approaches for Open-set Identification of Signals
… However, that changed when they were opened up in the 2010's. With these bands now being forced to co-exist with commercial users, military operators need systems to identify the signals within a spectrum environment. In this thesis, we extend current research in the area of signal …

Human action recognition in the real world: handling domain shift in open-set, source-free and multi-source scenarios
… base formulation, which is characterized by a set of assumptions that rarely hold in real-world scenarios; these include, for instance, full knowledge of the categories present in the target domain, as well as direct access to the data used to train the models. Driven by the purpose of dropping …

Underwater Semantic Simultaneous Localization and Mapping
… due to the lack of large labeled underwater datasets and the challenging sensor modalities specific to underwater environments. To address these shortcomings, this thesis develops a range of methodologies to advance underwater semantic SLAM capabilities. First, self-supervised learning and visual …

A Study of Concept Images and Concept Definitions related to Metric Spaces
… was specifically interested in the concept of an open set in a metric space. This work also addresses the topics of distance and open balls, which are both essential when considering open sets. Also, I sought to investigate the relationships between students’ concept images and the concept …

Outcomes of Auditory Brainstem Implantation in Adults with Postlingual Deafness: A Systematic Review
… measures have been categorized as either closed-set (CS) or open-set (OS). Total overall sample size across the 13 included studies was 170. Of the 170 participants, 91 (54%) were adults with postlingual deafness; 76 participants (84%) were adults with NF2, and 15 participants (16%) were adults …

Dynamics of Iterated Functions Systems: Hausdorff Dimension and Related Topics
… explores the Hausdorff dimension of fractal sets generated by iterated function systems (IFS). Hutchinson studied IFS and obtained a useful formula to compute the Hausdorff dimension of fractals generated by a finite family of disjoint similar IFS, where by disjoint we mean the IFS satisfies …

Extremal Discs and CR Geometry
… (1) A determination of the dimension of the set of extremal discs attached to a CR strictly pseudoconvex manifold of codimension two in C 4: we prove that, for such a manifold, extremal discs depend on 15 parameters, one more than the parameters needed to describe extremal discs attached to a …

The inverse limit of GIT quotients of Grassmannians by the maximal torus
… of this inverse system as a moduli space. An open set in this scheme represents the functor of arrangements of lines in planes. We show how to enrich this functor such that it is represented by the above inverse limit.

Convergence of Gibbs measures and the behavior of shrinking tubular neighborhoods of fractals and algebraic sets
… along self-similar fractals with Hutchinson's Open Set Condition. In Chapter 3 we study spaces of concentric circles (which we call targets) in the plane, and examine how the sequence of probability measures distributes over the targets. By varying the number of targets and the size of the …

Interpretable neural networks via alignment and dpstribution Propagation
… performance of 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 …

One-Dimensional Fractal Wave Equations
… defining these measures do not satisfy the open set condition or the post-critically finite condition, and therefore the existing theory, introduced by Kigami and developed by many other mathematicians, cannot be appled. First, by using a weak formulation of the problem, we prove the …

Potential Theory of Generalized Hyperbolic Processes
… hyperbolic processes in a bounded C1,1 open set D can be obtained from rotationally invariant Cauchy processes in D through a combination of a pure jump Girsanov transform and a Feynman-Kac transform. From this, we deduce that the Green functions for these two processes in D are …

Exploring the Role of Foundation Models for Training Generalist Robot Learning Policies
… difficulty generalizing to slightly different settings. In this work, we explore two approaches to training generalist robot learning policies using large-scale foundation models. The first approach aims to use a video foundation model to generate task-conditioned synthetic demonstrations at …

Asymptotic description of the formation of black holes from short-pulse data
… of the blown-up manifold and show that for an open set of restricted short-pulse data, the formal solution exhibits curvature blowup at a hypersurface in one of the boundary hypersurfaces of the desingularized manifold. This thesis is intended to be partially expository. In particular, this …

Stable and Unstable Shock Formation of the Burgers-Hilbert Equation
… For the stable shock, the initial data are in an open set in the 𝐻⁵ -norm, and the shock profile is a cusp with Hölder 1/3 continuity. For the unstable shock, the initial data are in a co-dimension 2 subset of the 𝐻⁹ space, and the shock profile is of Hölder 1/5 continuity. Both cases utilize a …
