A hierarchical representation of control knowledge for a heuristic classification shell
… etc. The objective of this thesis is a representation of control in a Heuristic Classification shell that can be used in problem solving and critiquing.

A multiscale approximation algorithm for the cardinality constrained knapsack problem
… steps: a rounding and reduction step where a hierarchical representation of the problem data ranging from coarse to fine is generated, a solution step where a coarse solution is computed, and a refinement step where the accuracy of the solution is improved by refining the problem …

Deformable models using displacement constraints
… propagated through the different levels of the hierarchical representation of the object. Animators can set the distribution of forces at each level, thus controlling an object's local and global behaviour.

The value hierarchies of J.R.R. Tolkien and his legacy: a reimagining of fantasy fiction and the propagation of colonial racism
… The biographical influence manifests in a hierarchical representation of everything from trees and their ancestry to the elves, humans, dwarves, hobbits, and orcs that populate his fiction. The hierarchies are value structures and the nearer to the top of the value structure, the more …

VisText: A Benchmark for Semantically Rich Chart Captioning
… In VisText, a chart is available as three representations: a rasterized image, a backing data table, and a scene graph — a hierarchical representation of a chart’s visual elements akin to a web page’s Document Object Model (DOM). To evaluate the impact of VisText, we fine-tune …

Hierarchical learning : theory with applications in speech and vision
Over the past two decades several hierarchical learning models have been developed and applied to a diverse range of practical tasks with much success. Little is known, however, as to why such models work as well as they do. Indeed, most are difficult to analyze, and cannot be easily characterized …

The cognition of atonal pitch structures
… internally organize atonal pitch sequences into hierarchical structures. Based on an information processing model proposed by Deutsch and Feroe (1981), the internal organization of well processed pitch sequences will result in the formation of hierarchical structures. The more efficiently …

Feature extraction and matching of palmprints using level I detail
… are used to form a novel compact tree-like hierarchical representation of the Level I detail. Matching between the latent and an exemplar is performed between their respective tree-like hierarchical structures. The methods developed within the thesis are complementary to current APIS …

Musical Ambiguity in Analysis and Composition: Problems of Pattern, Value, Form, and Structure
… of Haydn's Sonata no. 39 which features non-hierarchical representation of details within, and a network model of relationships across, the first nine phrases. Chapter Five defines two forms of structural ambiguity, diachronic and synchronic recomposition, within a discussion of "open works" …

Exploring screen summarization with large language and multimodal models
… They can be represented by both visual representations, (screenshots) and structural metadata (view hierarchies). The image modality is rich and can contain information such as images, colors and positional information, while the view-hierarchies represent a tree of UI Elements, with …

Physical finite elements
… structure in the mathematical model, creating a hierarchical representation of the assembly and treating each level independently. The results can reduce the cost to design and validate complex structures, in both the required computational resources, as well as the time and testing cycles of …

Learning structured representations by embedding class hierarchy with fast optimal transport
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2027-05-01

An Explainable Semantic Parser for End-User Development
… a natural language utterance to a formal command representation able to be processed by a computational machine. Currently, semantic parsers are typically built on the top of a learning method that defines its behaviours based on the patterns behind a large training data, whose production …

Structured video content analysis : learning spatio-temporal and multimodal structures
… of human behavior. The first algorithm, hierarchical sequence summarization, is a probabilistic graphical model that learns spatio-temporal structure of human action in a fine-to-coarse manner. It constructs a hierarchical representation of video by iteratively summarizing the video …

A Common Taxonomy for Modeling Construction Operations
… are developed here. This taxonomy identifies a hierarchical representation of construction projects based on operational considerations. The hierarchy consists of seven levels: product, assemblies and subassemblies, components, operations, processes, physics, and control. The hierarchical levels …

A Tool for Producing Verified, Explainable Proofs
… reason. The system provides a visual, hierarchical representation of the goal and a system for suggesting available inference rules. The system produces output in the form of both natural language and formal proof terms which are checked by Lean's kernel. This is made possible with the …

Automated structuring of text space with minimal supervision
… Construction and Enrichment. Constructing a hierarchical representation of knowledge from textual data is a crucial first step towards a structured text space. While existing works rely on substantial human efforts on maintaining such a taxonomic structure, I will introduce several works that …

Quantitative modeling and analysis with FMC-QE
… and prediction. In this new methodology, the hierarchical service requests are in the main focus, because they are the origin of every service provisioning process. Similar to physics, these service requests are a tuple of value and unit, which enables hierarchical service request …

Mining Functional and Structural Relationships of Context Variables in Smart-Buildings
… rules to produce device association groups, hierarchical representation of the building, or the relative location of spatial sensors. The proposed algorithms were tested using a year-long installation in a living-lab consisting of a four-person office, a 12-person open office, and a meeting …
