Uncertainty quantification in noisy networks
… Specifically, we study causal inference on noisy networks, and estimation of epidemic reproduction numbers in network-based and non-network-based settings. Ultimately, our work will bring critical insight into how ‘noise’ at the level of observed network connectivity impacts critical …

Nonclassicality in noisy quantum networks
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2024-03-01 without embargo terms

On boosting and noisy labels
… can be understood in terms of how it handles noisy (mislabeled) points. Confirming experimental evidence emerged from experiments using the Wisconsin Diagnostic Breast Cancer(WDBC) dataset commonly used in machine learning experiments. A majority vote ensemble filter identified on average that …

Program Synthesis over Noisy Data
… synthesis algorithms for program synthesis over noisy data, i.e., data that may contain incorrect/corrupted input-output examples. I model the process that produced the noisy dataset as the selection of inputs and a hidden program from an input source and program source followed by the …

Understanding Deep Learning with Noisy Labels
… In this thesis, we study deep learning with noisy labels from two aspects. Specifically, the first part of this thesis, including two chapters, is devoted to learning and understanding representations of data with respect to label noise. In Chapter 2, we propose a novel regularization …

Fractional Diffusion in Gaussian Noisy Environment
Three types of stochastic partial differential equations are studied in this dissertation. We prove the existence and uniqueness of the solutions and obtain some properties of the solutions. Chapter 3 studies the linear stochastic partial differential equation of fractional orders both in time and …

Adversarial Inverse Reinforcement Learning with Noisy Observations
… of log-likelihood optimization that accommodates noisy input. We adopt two techniques from the literature on learning hidden representations in sequential decision tasks and combine them with AIRL to solve this unified optimization problem. Experiments in four benchmark OpenAI Gym environments …

Coherence and synchronization of noisy-driven oscillators
… First, we demonstrate that the coherence of a noisy or chaotic self-sustained oscillator can be efficiently controlled by the delayed feedback. We develop the analytical theory of this effect, considering noisy systems in the Gaussian approximation. Possible applications of the effect for the …

Decomposition Evolutionary Algorithms for Noisy Multiobjective Optimization
… of the MOEA. In this thesis, we study the noisy MOP and modify the MOEA/D to improve its performance in noisy environments. To achieve this, we will combine the basic MOEA/D with the 'Ordinal Optimization' technique to handle uncertainties. The major contributions of this thesis are as …

Quantization for Noisy Channels Using Structured Codes
… criterion are derived for both noiseless and noisy discrete memoryless channels.

Fluid-structure interaction in noisy nonlinear systems
The first part of this work is concerned with the application of stochastic dimensional reduction to a twelve-dimensional aeroelastic model (i.e., two degrees of freedom that characterize the aerodynamics, two auxiliary degrees of freedom, and a four dimensional real noise process). The entire …

Predicting confusions and intelligibility of noisy speech
Current predictors of speech intelligibility are inadequate for making predictions of speech confusions caused by acoustic interference. This thesis is inspired by the need for a capability to understand and predict speech confusions caused by acoustic interference. The goal of this thesis is to …

Noisy-signalling models of organizational decision making
… channels and intermediaries in organizations. A noisy-signalling model of strategic communication is introduced in the first chapter, and expanded upon in the remainder of the thesis. In the second part of the first chapter, I use the core noisy-signalling model to study organizational design of …

Improving the quality of speech in noisy environments
In this thesis, we are interested in processing noisy speech signals that are meant to be heard by humans, and hence we approach the noise-suppression problem from a perceptual perspective. We develop a noise-suppression paradigm that is based on a model of the human auditory system, where we …

Identification of headers and footers in noisy documents
Optical Recognition Technology is typically used to convert hard copy printed material into its electronic form. Many presentational artifacts such as end-of-line hyphenations, running headers and footers are literally converted. These artifacts can possibly hinder proximity and exact match …
