Multimedia copy detection

Publisher: name: University of British Columbia

description: Asmultimedia-sharing websites are becoming increasingly popular, content providers get more concerned about the illegal distribution of their copyrighted contents. The recent content-based multimedia fingerprinting technology has evolved as an important tool for automatically detecting illegal copies of audio, image, and video signals. Multimedia fingerprints are signatures that are extracted from an audio, image, or video signal as a compact identifier of the signal. Therefore fingerprints should have enough discriminating ability to identify a multimedia object among others. At the same time they should be robust to modifications a multimedia signal might be subjected, such as compression, cropping, format change, scaling, and other signal processing operations. Robustness requires the fingerprints of a signal to only depend on the signals perceptual content and not on its format, size, quality, etc. This thesis proposes copy detection systems for audio and video signals and addresses the robustness as well as the discrimination ability of these systems. We first address audio fingerprinting and propose an algorithm that can detect small snippets of audio signals. Simulation results show that, the extracted fingerprints are robust to audio modifications including pitch shift and tempo change. For severe modifications that existing algorithms have poor detection rates (around 20%), our proposed algorithm yields detection rates above 80%. We then address video fingerprinting and propose an algorithm that extracts robust and discriminant binary fingerprints. Simulation results show that the proposed algorithm is faster and more accurate than the state-of-the-art with a high true positive rate of over 97% and a low false positive rate below 1%. Another challenge in multimedia fingerprinting is fingerprint retrieval, i.e. searching a huge fingerprint database (millions of fingerprints), for an accurate match for a query fingerprint in a fast fashion. We propose a fast and accurate Nearest Neighbour (NN) search algorithm for binary fingerprints (Hamming space). Tested on a very large database of 80 million images, we showed that the proposed algorithm is about 3 times faster than the state-of-the-art while at the same time it is 10 times more accurate.

description: Deep learning is a particular kind of machine learning which is powerful andflexible as a consequence of its ability to represent the world as a nested hierarchyof concepts (LeCun et al. 2015, Goodfellow et al. 2016). Due to the ever increasingpower of parallel computing graphics processing units, larger labelled datasets andimproved training techniques, great leaps in the performance of various machinelearning tasks have been achieved using deep learning (LeCun et al. 2015). At thetime of this writing, deep learning is the dominant machine learning approach formuch ongoing work in fields such as: Computer Vision (Krizhevsky et al. 2012, Heet al. 2016), Reinforcement Learning (Mnih et al. 2015, Silver et al. 2016), MedicalImaging (Ronneberger et al. 2015), and Natural Language Processing (Vaswaniet al. 2017, Devlin et al. 2019).However, with the uptake of deep learning models into safety-critical domains,transparency of model predictions is becoming increasingly important for: safety,decision-making, fairness and legislative reasons. Moreover, designing deep learning models that strike a good balance between human interpretability and performance has proven to be a challenging task (Caruana et al. 2015, Montavon,Lapuschkin, Binder, Samek & Müller 2017, Kendall & Gal 2017, Rudin 2019,Samek et al. 2019). With that said, in this thesis we advocate for an alternativeview of interpretability based on estimating the uncertainty in a model’s predictions, which serves as a proxy for model transparency. In our investigations,we formalise the desiderata of model transparency as: trust, information andgeneralisation, and take steps towards the development of deep learning modelswhich have the potential to satisfy them. Concretely, we leverage the language ofuncertainty to improve the performance and transparency of deep learning models in computer vision tasks, providing probabilistic techniques to enhance moreinterpretable models by design such as capsule networks.
From the orbit theory to a guiding center parametric distribution function

Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: This work proposes a parametric equilibrium distribution function F_eq to be applied to the gyrokinetic studies of the Finite Orbit Width behavior of guiding centers representing several species encountered in axisymmetric tokamak plasma, as fusion products, thermal bulk and energetic particles from Ion Cyclotron Radiation Heating and Negative Neutral Beam Injections. After the analysis of the basic results of orbit theory obtained with a particularly convenient orbit coordinates set, it is shown how the proposed F_eq satisfies the two conditions that make it an equilibrium distribution function: (i) it must depend only on the constants of motion and adiabatic invariants, and (ii) the guiding centers must remain confined for suitably long time. Furthermore, the F_eq can be modeled, with a proper choice of its parameters, to reproduce the most common distribution functions. A local Maxwellian distribution function is obtained for the thermal plasma in the Zero Orbit Width approximation. For the fusion αparticles, F_eq can also reproduce the Slowing Down (SD) distribution function. More generally, for supra-thermal particles, when external heatings are present, such as (N)NBI and ICRH, the proposed model distribution function shows similarities with the anisotropic SD and the biMaxwellian distribution functions. F_eq can be used to fit experimental profiles and it could provide a useful tool for experimental and numerical data analysis. Moreover, it could help to develop analytical computations for facilitating data interpretation in the light of theoretical models. This distribution function can be easily implemented in gyrokinetic codes, where it can be used to simulate plasma also in the presence of external heating sources.

description: For a locally compact group $G$ and $p \in (1,\infty)$, we define and study the Beurling-Figa-Talamanca-Herz algebras $A_p(G,ω)$. For $p=2$ and abelian $G$, these are precisely the Beurling algebras on the dual group $\hat{G}$. For $p =2$ and compact $G$, our approach subsumes an earlier one by H. H. Lee and E. Samei. The key to our approach is not to define Beurling algebras through weights, i.e., possibly unbounded continuous functions, but rather through their inverses, which are bounded continuous functions. We prove that a locally compact group $G$ is amenable if and only if one - and, equivalently, every - Beurling-Figa-Talamanca-Herz algebra $A_p(G,ω)$ has a bounded approximate identity.

Structural estimation and policy analysis applications in housing and education
Creators: name: Abbott, Brant
Publisher: name: University of British Columbia
Year: 2013

description: The first chapter studies the role of mortgage constraints in life-cycle housing decisions. I argue that observed Loan-to-Value (LTV) ratios contradict the view that large down-payments limit home ownership among young households. I estimate a model of life-cycle housing decisions that includes high LTV mortgages using a method of simulated moments. The model closely replicates home ownership rates over the life-cycle, but restricted models with maximum-LTV constraints cannot. Differences in estimated parameters lead to differences in the importance of credit-frictions, family composition and income risk in shaping ownership decisions. The second chapter studies the relationships among housing consumption inequality, credit market frictions and the price of housing in the context of the recent U.S. housing boom. Loosening lending standards, falling interest rates and speculation have all been cited as potential causes of the increase in the average price of housing. I identify the relative importance of each of these causes through a structural model that is estimated using housing consumption micro data. The price of housing is an endogenous feature of the model, which explains 61.8% of actual house price growth, of which 24.8% is due to the falling real interest rate, 20.1% is due to investor speculation and the remainder is due to a loosening debt-to-income ratio constraint. The estimated model replicates the increase in housing consumption inequality observed over the time period. The third chapter compares partial and general equilibrium effects of alternative financial aid policies intended to promote college participation. We build an overlapping generations life-cycle, heterogeneous-agent, incomplete-markets model with education, labor supply, and consumption/saving decisions. Altruistic parents make inter vivos transfers. Student labor supply and government grants and loans complement parental transfers as sources of college funding. We find that the current U.S. financial aid system improves welfare, and removing it would reduce GDP by two percentage points. Relaxation of government-sponsored loan limits would have no salient effects. The short-run partial equilibrium effects of expanding tuition grants are sizeable. However, long-run general equilibrium effects are 3-4 times smaller. Every additional dollar of government grants crowds out 20-30 cents of parental transfers.

description: We explore electrical transport through a point contact in strained HgTe, a three-dimensional topological insulator. In the absence of a magnetic field B, there is no quantization. However, under higher magnetic fields, we observe distinct noninteger conductance steps. Based on numerical tight-binding calculations and a phenomenological Landauer-Büttiker approach, we attribute these atypical, noninteger quantized plateaus to significant scattering effects at the point contact.

Biodiversity informatics and macroecological patterns of biodiversity: Uruguay as a model region

Publisher: name: University of Lincoln
Year: 2023
Subjects: C181 - Biodiversity

description: Biodiversity is declining at unprecedented rates in a rapidly changing world in which most species remain to be discovered. Thus, it is essential that countries generate mechanisms to quantitatively measure biodiversity and monitor its changes. Uruguay, in particular, covers a peculiar area where multiple bioregions of South America converge geographically, potentially driving unique biodiversity hotspots that result from the biogeographic connection of multiple bioregions. However, whether such hotspots exist in this country remains an open question, given the exceptionally limited knowledge about larger-scale biodiversity patterns. Although efforts have been made to document the distribution of biodiversity in Uruguay, comprehensive studies across the tree of life are limited and have received less attention. The aim of this study was to use Uruguay as a model region to quantify the patterns and processes of biodiversity across the Tree of Life. A key finding was to reveal that a strong sampling bias has historically affected the reconstruction of diversity patterns across all taxonomic groups in Uruguay. Therefore, it is not possible to draw definite conclusions as to whether the patterns of biodiversity we observe are real or fabricated by tactical sampling practices. This study highlights the critical knowledge shortfall situation in which Uruguay stands and, at the same time, suggests a first approach and a path to transit to start tackling this issue. Every finding in our study is a critical step towards the ambition to start a scientific quantification of biodiversityin this country, to provide a resource for organisations and scientists, and to raise awareness at the government level.

description: The thermal mean square displacement (MSD) of hydrogen in proteins and its associated hydration water is measured by neutron scattering experiments and used an indicator of protein function. The observed MSD as currently determined depends on the energy resolution width of the neutron scattering instrument employed. We propose a method for obtaining the intrinsic MSD of H in the proteins, one that is independent of the instrument resolution width. The intrinsic MSD is defined as the infinite time value of that appears in the Debye-Waller factor. The method consists of fitting a model to the resolution broadened elastic incoherent structure factor or to the resolution dependent MSD. The model contains the intrinsic MSD, the instrument resolution width and a rate constant characterizing the motions of H in the protein. The method is illustrated by obtaining the intrinsic MSD of heparan sulphate (HS-0.4), Ribonuclease A and Staphysloccal Nuclase (SNase) from data in the literature.

We perform a simple calculation showing that the geometric discord, a measure of quantum correlations, does decay to zero in the infinite acceleration limit. This result is seen to be a natural and expected consequence of considering correlations in an infinite dimensional system, and it sheds doubt on the existence of useable quantum correlations in this regime. We contrast our results with previous research showing that the acceleration-induced degradation of quantum discord was not strong enough to extinguish discord in the large acceleration limit.

title: DEPRECATED: DIGITAL ENCODING OF TELEVISION SIGNALS USING THE PULSE WIDTH MODULATOR
Creators: name: WADE, JOHN GRAHAM
Publisher: name: University of Plymouth
Year: 1975

description: An attempt is made to quantify the circuit complexity and mean circuit speed of linearly quantized straight PCM video encoding techniques. Any significant reduction in circuit complexity (i.e. the number of active and passive devices to be integrated) is considered important since this determines: chip area and yield if the encoder is to be fully integrated. Analysis indicates that the complexity of the more highly developed straight PCM video encoders can be reduced by typically a factor 3 using either non-programmed sequential encoding, pulse width modulator encoding or programmed sequential encoding (closed loop successive approximation). The encoder studied in this work is an 8-bit pulse width modulator video encoder using a 2-step production line technique and a detailed design procedure for a prototype encoder is given. This encoder is considered to achieve 7-bit resolution at a sampling rate of 13.3MHZ. A mathematical model of the encoder-decoder system is developed for numerical evaluation of the effect of encoder errors and white Gaussian noise upon a coded and decoded video signal. A triangular wave test is applied to examine the effect of encoder errors upon the statio transfer characteristic of the encoder. Dynamic errors are investigated by simulating colour subcarrier at the model input and observing the phase and gain errors at the filtered codec output. Using differential phase and gain, an attempt is made to determine a circuit design and alignment criterion such that most practical codecs will fall within specific bounds on these parameters (taken as ±6° and ±6% respective1y). In the absense of dither, Monte Carlo analysis indicates that the maximum voltage error incurred by each encoder error source should have a high probability (95%) of being less than a half quantum if 85 - 90% of codecs measured are to fall within the above bounds. If white Gaussian noise is used as a simple dither signal then the probability of a codec falling within the above bounds may increase to about 95%. Improvements to the encoder are discussed, including several automatic error correction techniques which combat instrumental errors and give a more robust PWM encoder. Also, by predetermining the most significant bit for each set of 4 coded bits it is possible to halve the encoder clock frequency (to 133MHZ) without significantly changing the encoder complexity.

I will also discuss on-going and future spectroscopic surveys of stellar streams.

The Milky Way is not special: Accreted stars also show the Spite Plateau in Lithium
Creators: name: Simpson, Jeffrey
Publisher: name: Zenodo
Year: 2021

description: The ESA Gaia astrometric mission has enabled the remarkable discovery that a large fraction of the stars near the Solar neighbourhood appear to be debris from a single in-falling system, the so-called Gaia-Enceladus. One exciting feature of this result is that it gives astronomers for the first time a large sample of easily observable, unevolved stars that formed in an extra-Galactic environment, which can be compared to stars that formed within our Milky Way. In this talk I will discuss using these stars to investigate the “Spite Plateau” – the near-constant lithium abundance observed in metal-poor dwarf stars across a wide range of metallicities (-3 < [Fe/H] < -1). In particular our aim was to test whether the stars that formed in Gaia-Enceladus show a different Spite Plateau to Milky Way stars that inhabit the disk and halo. Individual galaxies could have different Spite Plateaus – e.g., the interstellar medium could be more depleted in lithium in a lower galactic mass system due to it having a smaller reservoir of gas. We find that the Gaia-Enceladus stars show the same lithium abundance as other likely accreted stars and in situ Milky Way stars, strongly suggesting that the “lithium problem” is not a consequence of the formation environment. This result fits within the growing consensus that the Spite Plateau, and more generally the “cosmological lithium problem” – the observed discrepancy between the amount of lithium in warm, metal-poor dwarf stars in our Galaxy, and the amount of lithium predicted to have been produced by Big Bang Nucleosynthesis – is the result of lithium depletion processes within stars.

The Fimbulthul stellar stream was tidally stripped from the globular cluster ω Centauri
Creators: name: Simpson, Jeffrey
Publisher: name: Zenodo
Year: 2019

description: The Milky Way Galaxy formed in part through the accretion of smaller dwarf galaxies. Some of these events remain imprinted on the Galaxy in the form of stellar tidal streams: coherent kinematic and spatial structures of stars. The discovery of these streams has exploded recently thanks to deep photometric surveys (e.g., DES, Pan-STARRS) combined with the precise kinematic information from Gaia. One particular stream, Fimbulthul, has associated with the massive globular cluster ω Centauri[1, 2], but only with kinematics and metallicities. In this talk, I will use the abundance information from the GALAH survey to confirm this association of the Fimbulthul stellar stream to ω~Centauri using chemical tagging from over 10 elements with a range of dominant nucleosynthetic origins.

description: We present a thorough theoretical study of ordering phenomena in nitride ternary alloys GaInN, AlInN, and AlGaN. Using the Monte Carlo approach and energetics based on the Keating model we analyze the influence of various factors on ordering in bulk crystals and epitaxial layers. We characterize the degree of both short range order (SRO) and long ranger order (LRO) for different compositions, temperatures and for substrates associated with different epitaxial strain. For the description of the SRO the Warren-Cowley parameters related to the first four coordination shells are used. The LRO is detected by means of the introduced sim-LRO parameter, based on the Bragg-Williams approach. The description of the observed long-range ordering patterns and conditions for their occurrence follows.

description: Three challenges exist for human neurobiology, specifically in the areas of genomics and genetic medicine: understanding of genome regulation, understanding of central nervous system (CNS) development, and the lack of promoters for human gene therapy. To address these issues, we used computational biology strategies, primarily involving phylogenetic footprinting, to identify putative regulatory elements in genes with a regionalized or cell-type specific expression pattern. We generated human MiniPromoter constructs, less than 4 kilobases in size, and made genetically engineered mice by single-copy knock-in at the mouse Hprt locus. Neuroanatomical analyses were performed on brain and eye, primarily. Using this strategy, we generated 50 novel MiniPromoters for use in driving gene therapy constructs. Lastly, we demonstrated retained specificity of three retinal ganglion cell layer MiniPromoters when these were moved from knock-ins to an adeno-associated viral vector, exemplifying the utility of these constructs in other systems. In order to study CNS development, we chose to functionally analyze non-endogenous expression of the neural stem cell regulator NR2E1 in mice. We employed a DCX-based MiniPromoter from the Pleiades Promoter Project, in addition to the ubiquitous CAG promoter, to drive ectopic and ubiquitous expression of human NR2E1. DCX-based expression of human NR2E1 did not result in any overt phenotypes and was unable to rescue the brain and eye defects observed in Nr2e1frc/frc mice. In contrast, the CAG promoter resulted in embryonic death at ~E8, with failure of neural tube closure. We showed that expression of NR2E1 has negative effects on embryonic stem cell growth. Furthermore, we observed altered Pax6 expression in NSCs and embryos. Future work on promoter design and NR2E1 biology will advance our knowledge of genome regulation and CNS development.

description: We prove pathwise (hence strong) uniqueness of solutions to stochastic evolution equations in Hilbert spaces with merely measurable bounded drift and cylindrical Wiener noise, thus generalizing Veretennikov's fundamental result on $\mathbb{R}^d$ to infinite dimensions. Because Sobolev regularity results implying continuity or smoothness of functions do not hold on infinite-dimensional spaces, we employ methods and results developed in the study of Malliavin-Sobolev spaces in infinite dimensions. The price we pay is that we can prove uniqueness for a large class, but not for every initial distribution. Such restriction, however, is common in infinite dimensions.

description: We study the spectra of gamma ray signals that arise from dark matter annihilation in the universe. We focus on the large class of theories where the photon spectrum includes both continuum spectrum of gamma rays that arise from annihilation into Standard Model states at tree level, as well as monochromatic gamma rays arising from annihilation directly into two photons at the one loop level. In this class of theories we obtain lower bounds on the ratio of the strength of the gamma ray line relative to the gamma ray continuum as a function of the dark matter mass and spin. These limits are obtained from the unitarity relation between the tree level amplitude of the primary annihilation channel and the imaginary part of the loop level amplitude for annihilation directly into photons, with the primary decay products running in the loop. These results are exact in the limit that dark matter annihilation is exclusively to a single Standard Model species, occurs through the lowest partial wave and respects CP. Away from this limit the bounds are approximate. Our conclusions agree with the known results in the literature in the case of the Minimal Supersymmetric Standard Model (MSSM). We use the Fermi-LAT observations to translate these limits into upper bounds on the dark matter annihilation cross section into any specific Standard Model state.

Modernism, middlebrow and the literary canon in the modern library series, 1917-1955

description: Modernism, Middlebrow and the Literary Canon examines the evolution of cultural categories in mid-twentieth-century America through the study of the Modern Library, a cheap reprint series created in 1917. While the Modern Library has been described as a series of “highbrow” works that gradually became more commercial, my dissertation shows that it had always published a wide range of texts. I argue that the diversity of the Modern Library exemplifies the flexibility of cultural categories in the interwar period – a flexibility that was lost in the 1940s and 1950s when critics called for the separation between “high” and “low” cultural forms. I see the Modern Library as a large-scale institution of modernism that participated in the definition of the literary canon, and contributed to the popularization of writers such as James Joyce, Virginia Woolf and William Faulkner. In Chapter 1, I situate my methodology in relation to the various approaches employed by book historians, from biographical studies to quantitative analyses. Chapter 2 focuses on the inclusion of scientific essays and H. G. Wells’s controversial novels Ann Veronica and Tono-Bungay – a selection that contributed to the image of the Modern Library as a daring series for the civilized minority. Chapter 3 contends that the series participated in the early canonization of Sherwood Anderson by marketing Winesburg, Ohio and Poor White to a wide audience of instructors and students. Chapter 4 studies the publication of Fourteen Great Detective Stories and Joyce’s A Portrait of the Artist as a Young Man in the Modern Library. The fact that these two books were marketed and advertised in the same way exemplifies the blurring of the boundary between “highbrow” and “popular” texts in the interwar period. Chapter 5 looks at the Modern Library edition of Mrs. Dalloway. Despite her opposition to the “middlebrow,” Woolf accepted to write the introduction to widen her readership in North America. Chapter 6 examines the preface that Faulkner wrote for the Modern Library edition of Sanctuary. It shows that this introduction became controversial only in the late 1930s, when critics started dividing “high” culture from “lesser” works.
Holographic Entanglement Entropy for d=4 N=2 SCFTs in F-theory

description: We compute the holographic entanglement entropy in the gravity with higher curvature terms dual to d=4 N=2 SCFTs in F-theory using the method proposed in arXiv:1011.5819. The log term of this entanglement entropy reproduces the A-type anomaly of the dual SCFTs in F- theory using the gravity dual with the higher derivative term, which, using the field redefinition, can be transformed to the Gauss-Bonnet term in the subleading order of a derivative expansion. Our analysis shows that the 1/N^2 correction for the central charges should be produced from the gravity including higher derivative terms up to curvature squared terms. To obtain consistent results, we discuss the holographic c-theorem.

title: DEPRECATED: Reducing the Computational Effort Associated with Evolutionary Optimisation in Single Component Design
Creators: name: VEKERIA, HARISH DHANJI
Publisher: name: University of Plymouth
Year: 1999

description: The dissertation presents innovative Evolutionary Search (ES) methods for the reduction in computational expense associated with the optimisation of highly dimensional design spaces. The objective is to develop a semi-automated system which successfully negotiates complex search spaces. Such a system would be highly desirable to a human designer by providing optimised design solutions in realistic time. The design domain represents a real-world industrial problem concerning the optimal material distribution on the underside of a flat roof tile with varying load and support conditions. The designs utilise a large number of design variables (circa 400). Due to the high computational expense associated with analysis such as finite element for detailed evaluation, in order to produce "good" design solutions within an acceptable period of time, the number of calls to the evaluation model must be kept to a minimum. The objective therefore is to minimise the number of calls required to the analysis tool whilst also achieving an optimal design solution. To minimise the number of model evaluations for detailed shape optimisation several evolutionary algorithms are investigated. The better performing algorithms are combined with multi-level search techniques which have been developed to further reduce the number of evaluations and improve quality of design solutions. Multi-level techniques utilise a number of levels of design representation. The solutions of the coarse representations are injected into the more detailed designs for fine grained refinement. The techniques developed include Dynamic Shape Refinement (DSR), Modified Injection Island Genetic Algorithm (MiiGA) and Dynamic Injection Island Genetic Algorithm (DiiGA). The multi-level techniques are able to handle large numbers of design variables (i.e. > 100). Based on the performance characteristics of the individual algorithms and multi-level search techniques, distributed search techniques are proposed. These techniques utilise different evolutionary strategies in a multi-level environment and were developed as a way of further reducing computational expense and improve design solutions. The results indicate a considerable potential for a significant reduction in the number of evaluation calls during evolutionary search. In general this allows a more efficient integration with computationally intensive analytical techniques during detailed design and contribute significantly to those preliminary stages of the design process where a greater degree of analysis is required to validate results from more simplistic preliminary design models.
