Learning from multiple heterogeneous sources - Handling source trustworthiness and incompleteness
… source available. Making use of multiple sources can improve the quality of the labels and extend the size of the training data. However, these information sources have their own properties, and cannot be directly combined and utilized. We study the source heterogeneity from two major …

Monkey: A Distributed Orchestrator for a Virtual Pseudo-Homogenous Computational Cluster Consisting of Heterogeneous Sources
… the challenge of providing ample computational resources, and researchers are detracted from their core research in order to design, code, and configure experiments for the disparate computational resources provided. The framework proposed herein, therefore, strives to bridge the gaps between …

Stress-mediated reaction pathways for dislocation nucleation in copper
… nucleation, from either homogeneous or heterogeneous sources, in order to produce the large number of dislocations necessary for extensive plastic deformation. As with the majority of the defect processes that comprise deformation and failure of materials, dislocation nucleation is well …

Optimal Bayesian experimental design in the presence of model error
… setting, which naturally incorporates heterogeneous sources of information. An objective function reflects expected information gain from proposed experimental designs. Monte Carlo sampling is used to evaluate the expected information gain, and stochastic approximation algorithms make …

Successive structuring of source coding algorithms for data fusion, buffering, and distribution in networks
… to deal with the distributed processing, the heterogeneous sources of information, and the uncertain operating conditions that typify many networks. We investigate the broad interactions between estimation and communication in the context of data fusion in tree-structured sensor networks. We …

Towards integrated document processing and file browsing
… Site may contain multiple data types in distinct heterogeneous sources, and stored under different formats. It is impossible to rely on the Web browser to access multimedia database on the Internet, and to view a variety of file formats. For many years, people have been seeking a file browser …

Large-Scale Pattern Discovery in Music
… The result is the largest research dataset with heterogeneous sources of data available to music technology researchers. We demonstrate some of its potential and discuss the impact it already has on the field. On cover song recognition, we must revisit the existing literature since there are no …

Metadatenverwaltung zur qualitätsorientierten Informationslogistik in Data-Warehouse-Systemen
… decisions. The integration of data coming from heterogeneous sources is one of the key problems in data warehousing. The technical foundations for the integration have been developed in recent years. However, an efficient technical infrastructure is not sufficient to address the following …

Graph-based Vector Search Algorithms for Retrieval-Augmented AI Systems
… graph-based ANNS algorithm. (2) Data is heterogeneous in format, modality, and how they relate to a query, making the similarity difficult to capture by the canonical ANNS definition. I explore ways to model the similarity between heterogeneous sources and using graph-based ANNS …

Iterative Computing over a Unified Relationship Matrix for Information Integration
… Relationship Matrix (URM) to represent a set of heterogeneous data objects and their inter-relationships. I argue that integrated and iterative computations over the Unified Relationship Matrix can help overcome the data sparseness problem (a common situation in various information application …

A Chinese Writer's Vicissitude in the Political and cultural Context of Early Modern China
… that Early Modern Chinese nationalism has heterogeneous sources deriving from earlier intellectual histories.

Multimodal learning and language models for enhanced knowledge representations
… insights. Effectively integrating these heterogeneous sources remains one of the most significant open challenges in artificial intelligence research. In this thesis, I directly address this challenge by proposing three pioneering contributions that leverage multimodal data through …

Bayesian Pharmacokinetic Models for Inference and Optimal Sequential Decision Making with Applications in Personalized Medicine
… exploration of novel variables using data from heterogeneous sources. These contributions provide methodologies do address two central goals of personalized medicine -- identification of factors driving between patient variability in drug response, and selection of an optimal dose -- and can …

Lattice Based Elastic Metamaterials with Ultra-wide Stopbands at Low Frequency
… inevitable system uncertainties stemming from heterogeneous sources in practical EMMs can lead to significant fluctuations in structural performance, and worse still, catastrophic structural failure may occur. Consequently, to facilitate the wide and safe application of these advanced …

Multidimensional Spectroscopy With Femtosecond Pulses
… enables distinction between homogeneous and heterogeneous sources of nonexponential rates. The specifics of this set up will be detailed, as well as the results of a run performed on cadmium selenide quantum dots. After removing a fast biexciton effect that existed in the first 10 ps, the …

Rethinking Algorithm Design for Modern Challenges in Data Science
… corrupted, but because it comes from a number of heterogeneous sources. In the third part of this thesis, we give improved algorithms for two popular models of heterogeneity, mixtures of product distributions and mixtures of linear regressions, by developing novel ways of using Fourier …

A framework for evaluating semi-structured hierarchical data using language models
… pipelines. Limited guidance is available on how heterogeneous sources should be transformed into structure-preserving representations, how alternative model adaptation strategies should be compared, and how the impact of structural information should be quantified in a reproducible manner. This …

Assembling The Building Blocks For A Unified Splicing Code
… developing splicing code models: integrating heterogeneous sources of experimental data, modeling the transcriptomic state of tissues and effect of regulatory perturbations, modeling complex splicing variations from noisy measurements, and interpreting these models to generate high confidence …

A Study Of Computational Problems In Computational Biology And Social Networks: Cancer Informatics And Cascade Modelling
… model to identify cancer drivers. I utilize heterogeneous sources of information to discover cancer drivers and unlocking the mechanism behind cancer. Above all, I encode various pieces of biological information to form a multi-graph and trigger various Markov chains in it and rank the genes …

Statistical issues in Mendelian randomization: use of genetic instrumental variables for assessing causal associations
… gene–phenotype–outcome data from multiple heterogeneous sources. Methods for imputing missing genetic data are developed, allowing multiple genetic variants to be used without reduction in sample size. We focus on the question of a binary outcome, illustrating how the collapsing of the odds …
