description: This paper examines the definition of contemporary art as a postconceptual art in relation to conceptual art’s attempt at dematerialisation. In the conceptual moment, artists aimed to meld art with life, and many conceptual practices involved a sense of invisibility of both artwork and artist. The strategy of giving up art, prefaced by the actions of Duchamp and Warhol, proved intrinsic to art of this time. Here, art attempted to disappear, in line with the self-referential tendency of the modern to reveal its ultimate concept.Peter Osborne defines contemporary art in relation to the failure of this attempt to escape the material and aesthetic, finally articulating these qualities as inherent to the concept ‘art’. In his essay On Disappearance (2006), Baudrillard speaks of the strategy of disappearance as potentially evading death; here, conscious disappearance before one dies enables such escape. As a post-conceptual art, the contemporary inherits this movement’s outcomes, the result of its attempt to disappear. This strategy is seen to have failed, the art of the current moment rematerializing both in theory and practice; this paper will consider a definition of contemporary art less in relation to its multitude of particularities and instances, and more in relation to strategy. It will define contemporary art relative to conceptual art’s attempt to disappear, in precisely the manner Baudrillard describes. It examines our failure to achieve this, and attempts to historically and ontologically define the art of the current moment.

description: If Dark Eden is a spectral landscape and the material for a new culture, it is not so because of any sense of descent from the grand narrative of enlightened homo. In that story the narrative is working exactly as it is meant to, operating in a space of twenty-four hour illumination and productivity tied up in the visually biased “voraciousness of contemporary capitalism.”(1) Within that saturated landscape the dark has been white-washed and the histogram is leaning a little too heavily to the right. My paper draws from my recent thesis engaging the conceptual practice of ‘going dark’ as a methodology and tool of intervention. The accompanying social media project delivered dark text tiles, images and audio detailing a speculative fiction randomly transmitted via a sequence of hashtags to co-mingle alongside bright images of selfies, food, cats, and news. My project explores the case for dark as a thing with “thing-power”(2) and urges for a reorientation within its sphere of influence rather than separate or outside. To go dark is to engage in steady observation and a slow liveliness, to embrace the unfamiliar and attend to a practice of deviation indifferent to the temporal scales of productivity and possessive individualism. In this paper I offer the inverse and propose any notion of a current dark Eden is not because it is dark but rather because it is blazing. Simultaneously I suggest the bright Eden of paradise was always dark, always a multi-sensory affair entangled in relational and sensorial affects.1.

description: We determine a general upper bound for the steady-state entanglement achievable by continuous feedback for systems of any number of bosonic degrees of freedom. We apply such a bound to the specific case of parametric interactions - the most common practical way to generate entanglement in quantum optics - and single out optimal feedback strategies that achieve the maximal entanglement. We also consider the case of feedback schemes entirely restricted to local operations and compare their performance to the optimal, generally nonlocal, schemes.

A comparison between metropolitan and non-metropolitan residential mortgage financing in British Columbia
Creators: name: Burns, David O.
Publisher: name: University of British Columbia
Year: 2010

description: It is the purpose of this study to explore regional variation in the source, allocation, and characteristics of residential mortgage financing in British Columbia. In order to do so, the study compares and contrasts mortgage funds from two groups of communities. The two groups of communities are representative of the Greater Vancouver area and the outlying, 'smaller' or non-metropolitan communities. While the outlying municipalities are generally referred to as 'smaller' than the Vancouver municipalities, this is not necessarily the relevant characteristic. What is perhaps more important is that the Vancouver municipalities fall within a metropolitan region and the others do not. This study finds that significant regional variation in mortgage financing characteristics does not exist in all cases. Nonetheless, there does exist some variation which seems to be the result of two factors: (1) the variation in lender-type from the metropolitan area to the non-metropolitan community and (2) the relative price of housing in Greater Vancouver versus the non-metropolitan communities

description: The poster for Model Reduction and Surrogate Modeling (MORe2024), presaved for a preprint paper.

We propose a non-intrusive parametric MOR method named Data-Augmented Predictive Deep Neural Network (DAPredDNN) that employing CAE-FFNN and KDMD for dynamics prediction in both the time and the parameter space. The proposed method enriches original data by augmenting the KDMD-decoder-extrapolated data during the offline stage. Training the CAE-FFNN with this augmented data allows the network to correlates time-parameter pairs with their extrapolated solution directly, avoiding the time-marching behaviour during the online phase.

Planet formation in Alpha Centauri A revisited: not so accretion-friendly after all

description: We numerically explore planet formation around alpha Cen A by focusing on the crucial planetesimals-to-embryos phase. Our code computes the relative velocity distribution, and thus the accretion vs. fragmentation trend, of planetesimal populations having any given size distribution. This is a critical aspect of planet formation in binaries since the pericenter alignment of planetesimal orbits due to the gravitational perturbations of the companion star and to gas friction strongly depends on size. We find that, for the nominal case of a MMSN gas disc, the region beyond 0.5AU from the primary is hostile to planetesimal accretion. In this area, impact velocities between different-size bodies are increased, by the differential orbital phasing, to values too high to allow mutual accretion. For any realistic size distribution for the planetesimal population, this accretion-inhibiting effect is the dominant collision outcome and the accretion process is halted. Results are robust with respect to the profile and density of the gas disc: except for an unrealistic almost gas-free case, the inner accretion safe area never extends beyond 0.75AU. We conclude that planet formation is very difficult in the terrestrial region around alpha Cen A, unless it started from fast-formed very large (>30km) planetesimals. Notwithstanding these unlikely initial conditions, the only possible explanation for the presence of planets around 1 AU from the star would be the hypothetical outward migration of planets formed closer to the star or a different orbital configuration in the binary's early history. Our conclusions differ from those of several studies focusing on the later embryos-to-planets stage, confirming that the planetesimals-to-embryos phase is more affected by binary perturbations.

description: We investigate the infrared (IR) effects of Lorentz violating terms in the gravitational sector using functional renormalization group methods similar to Reuter and collaborators. The model we consider consists of pure quantum gravity coupled to a preferred foliation, described effectively via a scalar field with non-standard dynamics. We find that vanishing Lorentz violation is a UV attractive fixed-point of this model in the local potential approximation. Since larger truncations may lead to differing results, we study as a first example effects of additional matter fields on the RG running of the Lorentz violating term and provide a general argument why they are small.

Housing prices, government policy, and urban decay: a tentative hypothesis, a possible connection, and a policy suggestion
Creators: name: Cox, James Clayton
Publisher: name: University of British Columbia
Year: 2010

description: The development of significantly different housing prices in Canada and the United States was an issue of popular concern in recent years when Canadian housing prices were undergoing almost unprecedented price increases. The purpose of this paper was to determine the underlying causes of the differential in housing prices in Canada and the United States. The research methodology followed in the preparation of this paper involved the analysis of the housing markets of Seattle and Vancouver to determine what factors might have influenced prices in these two cities. The factors considered include housing stocks and starts, population, income, credit conditions, and the impact of the state. In general the findings suggest that the price differential has evolved because of a comparatively higher level of housing demand in the Vancouver housing market.

description: We continue our study of BPS equations and supersymmetric configurations in the Bagger-Lambert theory. The superalgebra allows three different types of central extensions which correspond to compounds of various M-theory objects: M2-branes, M5-branes, gravity waves and Kaluza-Klein monopoles which intersect or have overlaps with the M2-branes whose dynamics is given by the Bagger-Lambert action. As elementary objects they are all 1/2-BPS, and multiple intersections of $n$-branes generically break the supersymmetry into $1/2^n$, as it is well known. But a particular composite of M-branes can preserve from 1/16 up to 3/4 of the original ${\cal N}=8$ supersymmetries as previously discovered. In this paper we provide the M-theory interpretation for various BPS equations, and also present explicit solutions to some 1/2-BPS equations.

On methods for the maximization of a zero-one quadratic function
Creators: name: Hawkins, Stephen Peter
Publisher: name: University of British Columbia
Year: 2010

description: The research addresses the problem of maximizing a zero-one quadratic function. The report falls into three main sections. The first section uses results from Hammer [12] and Picard and Ratliff [23] to develop a new test for fixing the value of a variable in some solution and to provide a means for calculating a new upper bound on the maximum of the function. In addition the convergence of the method of calculation for the bounds is explored in an investigation of its sharpness. The second section proposes a branch and bound algorithm that uses the ideas of the first along with a heuristic solution procedure. It is shown that one advantage of this is that it may now be possible to identify how successful this algorithm will be in finding the maximum of a specified problem. The third section gives a basis for a new heuristic solution procedure. The method defines a concept of gradient which enables a simple steepest ascent technique to be used. It is shown that in general this will find a local maximum of the function. A further procedure to help distinguish between local and global maxima is also given.

subject: FOS: Arts (arts, history of arts, performing arts, music)

description: This text frames two contemporary demonic monuments as zombie monoliths within the area of expanded image, for they resuscitate the iconographic corpse of their idols while leaving a pious entity behind. These are Pazuzu (2008) by artist Roberto Cuoghi, a 5.7-meter reproduction of a small talisman depicting Mesopotamian demon Pazuzu, originally shown at the Castello Di Rivoli. And The Statue of Baphomet (2015) by the non-theistic organisation The Satanic Temple, a 2.6-meter public monument to the occult icon Baphomet rejected by Oklahoma State Capitol and Arkansas State Capitol in the USA. Both statues are post-secular, for Cuoghi conjured the dead image of Pazuzu to meditate on the fall of Empire, while The Satanic Temple devised The Statue of Baphomet as a ploy against a monument to the Ten Commandments sitting on State Capitol; advocating for the separation of church and state. Thus, their cadavers stand erect yet vacant, failing to summon the supernatural beings they represent.I draw from Hans Belting Anthropology of Images to argue that Pazuzu and The Statue of Baphomet resuscitate the body, but not the soul, of these idols in a necromancy that typifies Dark Eden. Indeed, Belting separates the anatomy of the image into image, medium and the receptive body—the first of which mirrors the split between soul and body. Teasing out the connotations of this framework, this text touches on practices of resurrection and the figure of the undead to put forth a semiotic necromancy as the darkness of the contemporary image.

description: Images produced by video surveillance have long been remediated by artists such as Harun Farocki, Hito Steyerl, or Walid Raad, conceptualizing them in the context of emerging media. As a networked medium, the live video feed has become the cinematic sensorium of the post-human individual, currently trapped in isolation and driven by the experience of deep sadness. Wildlife webcams become screens for the viewer's mental images; their temporal and semantic stasis allows for a poetic mode of viewing that transcends the material image and turns it into an affective membrane that resonates with the uncertainty of the present moment. From the viewer's confinement, reality becomes framed by the camera; the wilderness becomes public space negating human existence, amplifying the feeling of loss and grief, yet offering connection. The longing for something to happen in front of our eyes; the sensationalism and poetics of the gaze turn scopophilia into semantophilia. The live feed's temporal synchronicity offers an unexpected intensity to address the paralyzing and yet aggravating state of the world.This paper pairs up with a media artwork (by the same author) which invites the viewer to wander in a dark maze of virtuality reality followed by the auditory and visual echo of several live webcams.

description: In this paper I present insights and imagery from my research that is relevant to both researchers and artists, showing how visualised data, gathered from the darkest human experiences, illuminates what it is like to dwell in Dark Eden. A glimpse of a way in, and of a way out is offered by crossing the boundaries between art and science. Mapping over 200,000 people’s personality dynamics along with their everyday experiences, I discovered that Aesthetic Experience is extremely high where fear and situational risks are also at their highest, and all aspects of agency - purpose, engagement and resilience - are at their lowest ebb. How can this be? And what does it tell us about the role of Aesthetic Experience in navigating Dark Eden? Is it a blessing or a curse? A source of inspiration and hope in an almost impossible situation? Or held in the clutches of fear, does it simply drive you crazy? Informed by the writings of J Dewey, J Drucker and L Manovich, my research uses interactive psychological landscapes to give visibility to experiences that are not normally accessible. Pathways can be found, not by flooding Dark Eden with light, but by becoming accustomed with the darkness itself where the transformational role of Aesthetic Experience plays out.

Feasibility of salmon farming as a small business in British Columbia
Creators: name: Fralick, James Edward
Publisher: name: University of British Columbia
Year: 2010

description: The hypothesis was that salmon farming can be the basis for the establishment of a viable small business in British Columbia. The constraints on the establishment of a salmon farm imposed by government regulations, the availability of funds, and the market for pan-size salmon were presented and discussed. The pertinent biological knowledge associated with the rearing of captive salmon was summarized. A simple production model designed to produce approximately one-half million marketable, pan-size salmon within 15 months was derived from published accounts of studies at experimental fish farms. A hypothetical salmon farm was described in detail including estimates of the capital and operating costs associated with the farming and processing activities. The required information was obtained through interviews with knowledgeable members of the industry. The estimated revenues and expenses attributed to the hypothetical farm were analysed using pro forma financial statements to ascertain the financial position and the net cash flow which may be expected. The profitability of the farm was analysed by applying net present value and internal rate of return criteria to the net cash flow. Sensitivity analysis of the effect of changes to the product mix. market price, labour rate, feed price, tax rate, and stocking density upon the profitability of the farm was conducted. Estimates of the critical values of the above parameters which would allow the farm to be a feasible investment opportunity were derived. The conclusion is that pan-size salmon farming can be a feasible small business in British Columbia.

description: It seems to be almost anachronistic to speak of beauty after the twentieth century. But both from the philosophers and from the builders of the space (ordinary and extraordinary, that is, artistic), there still seems to be a request for beauty, especially in the last years. Is it possible to believe that the aesthetic category of beauty can still have a promising present, and a promising future? If the answer is yes, then what could a notion of beauty that is sustainable in the present and in the future mean? The objective of the following pages is to argue that a possible answer could be a notion of beauty analogous to a notion of grace, one endowed with a particular ethical meaning. The result is a notion of beauty that could be called found beauty.

description: This paper will discuss my exploration of the multiple nature of places in Western culture(s) in the 2020 artwork 'We went to school here'.(1) I used this work to draw on the gallery floor the footprint of the school building that previously occupied that same place, so that ex-school students could bring together their remembered images of it with the actual place in which it existed. It proposed that both the gallery and the school could briefly co-exist both visibly and actually: the gallery visible in the normal way to sighted people who actually entered it, and the school visible to those actually entering that same space but with remembered images of when they occupied it as a school.It will also discuss its optimistic proposal of a conjunction of remembered image and actual place as one way of challenging modernity’s devaluation of place (the latter discussed using accounts by writers as apparently diverse as Jane Bennett and Anthony Giddens).It intends to remind people that places have histories, even if, in the absence of traditional personal recognition, the location of earlier occupations sometimes needs to be confirmed with modern technical data, as is the case with this work. Most importantly, in having histories, places become more than their present occupation.The paper will also discuss the role of explanatory text that accompanies artwork such as this, because, despite occupying the whole gallery, the work itself is like its intended content in being invisible to most visitors.(1) http://margaretroberts.org/Wewent.html

description: "I have dealt with many different transformations with various periods of time, but the quickest that I have met was my own transformation in one moment from a physicist to a chemist." Ernest Rutherford (Nobel Banquet, 1908) This article is about how Ernest Rutherford (1871-1937) got the 1908 Nobel Prize in Chemistry and why he did not get a second Prize for his subsequent outstanding discoveries in physics, specially the discovery of the atomic nucleus and the proton. Who were those who nominated him and who did he nominate for the Nobel Prizes. In order to put the Prize issue into its proper context, I will briefly describe Rutherford's whereabouts. Rutherford, an exceptionally gifted scientist who revolutionized chemistry and physics, was moulded in the finest classical tradition. What were his opinions on some scientific issues such as Einstein's photon, uncertainty relations and the future prospects for atomic energy? What would he have said about the "Theory of Everything"?

description: We suggest and analyze a novel technique for efficient and robust creation of dense ultracold molecular ensembles in their ground rovibrational state. In our approach a molecule is brought to the ground state through a series of intermediate vibrational states via a {\em multistate chainwise Stimulated Raman Adiabatic Passage} (c-STIRAP) technique. We study the influence of the intermediate states decay on the transfer process and suggest an approach that minimizes the population of these states, resulting in a maximal transfer efficiency. As an example, we analyze the formation of $^{87}$Rb$_{2}$ starting from an initial Feshbach molecular state and taking into account major decay mechanisms due to inelastic atom-molecule and molecule-molecule collisions. Numerical analysis suggests a transfer efficiency $>$ 90%, even in the presence of strong collisional relaxation as are present in a high density atomic gas.
The Neuropsychological Impact of Conflict: An Analysis of Implicit Prejudice among Victims, Ex-combatants and Communities in Colombia
Creators: name: Ugarriza Uribe, Juan Esteban
Publisher: name: Universidad del Rosario
Year: 2024

description: Armed conflict impacts individuals at psychological level not only by causing illness, but also by affecting the mechanisms of information processing, opinion formation and decision-making. These effects negatively influence the effectiveness and durability of inter-group reconciliation approaches that ignore the protracted nature of biologically-driven implicit biases. By means of a computer-based Implicit Association Test (IAT), we tested pre-cognitive intergroup prejudices of 251 war victims, former guerrillas and victims in Colombia. We find that while ex-guerrillas identify themselves with the victims, there is a systematic bias against former combatants among communities and even more so among war victims. These results show not only that these groups have fundamentally different understandings of their immediate past of violence, but also that these conceptions are neurologically-imprinted in their cognitive and emotional processing mechanisms. We conclude on the need to deal with the neuropsychological effects of war on people’s dispositions and perceptions in postconflict societies.

Esta capacidad para relacionarnos con nuestras familias y con otras personas de nuestra comunidad (trabajo, colegio, barrio, vereda) se vuelve muy importante cuando nosotros, nuestros familiares o amigos se han expuesto a situaciones difíciles como las que se presentan en escenarios violentos, como el conflicto armado colombiano. En estas situaciones o escenarios, nuestras habilidades sociales y cognitivas enfrentan el reto de manejar situaciones, en algunos casos, extremas y hostiles. Es así como los entrenamientos en estas habilidades (cognición social), se convierten en una herramienta clave para que individuos y comunidades aprendan a responder efectivamente a estas problemáticas, fortaleciendo las capacidades para relacionarse con otras personas en diferentes dinámicas sociales y contextos difíciles.

description: As our corporeal experiences were catapulted by COVID-19 to an increasingly abstract datascape, the curatorium of Katherine Moline, Angela Goddard, Blaklash (Amanda Hayman and Troy Casey) and Beck Davis postponed the exhibition The Data Imaginary: Fears and Fantasies at Griffith University Art Museum, Brisbane to 2021. Our original aim—to explore data experiments in relation to climate change, data security and urban landscapes, many informed and shaped by Indigenous knowledges—had become our reality with the global pandemic. The challenge to the norms and standards of the social imaginary—how data operates and for whom it is operationalised—made by artists, designers and scientists have become a platform for survival – outside of the gallery and in our everyday worlds. The public fears and fantasises regarding data analysis throughout the pandemic now guide our curatorial framework. This paper will explore how the curators and exhibition participants have reformulated The Data Imaginary exhibition for pandemic life in a dark Eden and how we are reviewing the selection of works so that for example, Lola Greeno’s embodied knowledge of how climate change is impacting the materiality of Palawa shell stringing on the shores of the cool waters surrounding Lutruwita (Tasmania), contrasts with Silvio Carta’s dystopian vision of human value in The Machine’s Eye - How machines see our world alongside a workshop on data security by Make or Break now made necessary by a life of ISO.
SIMQ: a methodology for simulation by questionnaire
Creators: name: Goulet, Maurice Eugene
Publisher: name: University of British Columbia
Year: 2010

description: This paper presents SIMQ, a method of simulation program generation through questionnaires. Simulation is a powerful technique for analyzing complex systems; Hut its, acceptance has been impeded by the high cost of computer simulations. The objective of SIMQ is to enhance the usefulness of computer simulation by reducing the cost of developing simulation programs. Related research is reviewed in order to outline the development of the concept of program generation and to provide a standard of comparison for SIMQ. The structure and use of SIMQ is explained and then illustrated through application to a demonstration problem. Initially, the discussion centers on a basic version of SIMQ. Subsequently an extension of SIMQ is presented which permits stochastic branching within the model. Finally, an interactive graphical front end for the SIMQ system is described. Several experiments were conducted to test SIMQ's efficiency and characteristics. Results of field tests are also reported. Possible further extensions to SIMQ are outlined in the final chapter. The major conclusion reached is that the concept of program generation through questionnaires is feasible and that the structure of the SIMQ system is valid and useful.
Are the Military Ideologically-Driven? Explicit and Implicit Political Biases Among Armed Forces in Colombia

description: What motivates the military to fight in contemporary wars? Literature tells us soldiers are typically willing to engage in risky military actions due to their interpersonal loyalty to their comrades, and the sense of fighting for a moral cause. By building up a novel database  of a representative sample of members from Colombian Armed Forces who actually fought in the battlefield against Marxist guerrillas between 1990 and 2017, and relying on computer-based tests, here we systematically measure both explicit and implicit  war motivations. Our results suggest that ideology remains a systematic stimulus in soldiers’minds, both at conscious and unconscious levels, therefore affecting key behavioral aspects such as cohesion, task performance, and adherence to specific tactic and strategic principles on the ground. Prevalence of such stimulus even after active confrontation has ended might also point at a potential explanatory factor to veterans’social and political behavior.
Effects of Sample Specific Variations and Fluctuations of Thermal Occupancy on Fluctuations of Thermodynamic Quantities

description: Standard results for the fluctuations of thermodynamic quantities are derived under the assumption of sampling identical systems that are in different, not fully equilibrated states. These results apply to fluctuations with time in a particular macroscopic body and can be traced to the fluctuations of thermal occupancy. When many identically prepared - but not identical - systems are studied, mesoscopic fluctuations due to variations from sample to sample contribute to the fluctuations of thermodynamic quantities. We study the combined effect of mesoscopic fluctuations and fluctuations of thermal occupancy. In particular, we evaluate the total particle number and specific heat fluctuations in a two-dimensional, non-interacting electron gas in classically integrable and chaotic circumstances.

description: Retrospective artifact correction (RAC) improves image quality post acquisition and enhances image usability. Recent machine learning driven techniques for RAC are predominantly based on supervised learning and therefore practical utility can be limited as data with paired artifact-free and artifact-corrupted images are typically insufficient or even non-existent. Here we show that unwanted image artifacts can be disentangled and removed from an image via an RAC neural network learned with unpaired data. This implies that our method does not require matching artifact-corrupted data to be either collected via acquisition or generated via simulation. Experimental results demonstrate that our method is remarkably effective in removing artifacts and retaining anatomical details in images with different contrasts.

description: In order to answer the open questions of modern cosmology and galaxy evolution theory, robust algorithms for calculating photometric redshifts (photo-z) for very large samples of galaxies are needed. Correct estimation of the various photo-z algorithms' performance requires attention to both the performance metrics and the data used for the estimation. In this work, we use the supervised machine learning algorithm MLPQNA to calculate photometric redshifts for the galaxies in the COSMOS2015 catalogue and the unsupervised Self-Organizing Maps (SOM) to determine the reliability of the resulting estimates. We find that for spec-z<1.2, photo-z predictions are on the same level of quality as SED fitting photo-z. We show that the SOM successfully detects unreliable spec-z that cause biases in the estimation of the photo-z algorithms' performance. Additionally, we use SOM to select the objects with reliable photo-z predictions. Our cleaning procedures allow to extract the subset of objects for which the quality of the final photo-z catalogs is improved by a factor of two, compared to the overall statistics.

Statistics-Driven Texture Sound Synthesis Using Differentiable Digital Signal Processing-Based Architectures
Creators: name: Gutiérrez, Esteban
Publisher: name: Zenodo
Year: 2024

description: This thesis investigates the application of Differentiable Digital Signal Processing (DDSP) architectures to the synthesis and control of texture sounds. Texture soundsynthesis presents unique challenges due to the complex, non-pitched and noisy nature of these sounds, which differ significantly from pitched instrument timbres forwhich DDSP was originally designed. The core of this research consists in developing novel differentiable signal processors and loss functions tailored to the characteristicsof texture sounds, and integrating these innovations into DDSP-based frameworks.Two synthesizers are introduced: the SubEnv Synth, which imposes amplitude envelopes in a subband decomposition of white noise; and the P-VAE Synth, which combines a Poisson process with a Variational Autoencoder (VAE) to deal with time and events respectively. This approach is directly inspired by Saint-Arnaud’s original conception of texture sounds. Additionaly, the TextStat loss function, designed to compare texture sounds based on their statistical properties rather than short-term perceptual similarity, is also presented. This loss function is strongly inspired by McDermott and Simoncelli’s work.The thesis details the implementation of two DDSP-based architectures incorporating these synthesizers and the TextStat loss function. Results demonstrate that the SubEnv Synth successfully resynthesizes texture sounds with some succes, while the P-VAE Synth faces learning challenges. These challenges might be related to its VAE module’s complexity, however more research is needed to make this claim. Additionally, this research explores model variations that show potential for improved performance and suggests future work including the optimization of the TextStat loss function, reconsideration of VAE use, and real-time implementation of the developed models.Overall, the contributions of this thesis provide a foundation for advancing texture sound synthesis, offering new tools and insights for both theoretical exploration andpractical applications in the field of audio signal processing.
