Towards DESRED: A Diverse Explorable Super Resolution Evaluation Dataset
No full textThe task of explorable super resolution (ESR) reconstructs multiple possible high resolution (HR) image variants for a given single low resolution (LR) image. However, due to the novelty and complexity of ESR, there is currently no way to properly evaluate accuracy and diversity across ESR methods, instead relying on single image ground truths for evaluation, which cannot reflect the diverse space of HR images that ESR methods construct. This work aims towards solving this deficiency within the task of ESR by introducing DESRED: a Diverse Explorable Super Resolution Evaluation Dataset. The goal of this dataset is to produce multiple diverse, high-quality, and photorealistic HR images from single LR images, such that each set of HR images correspond exactly to the same LR image when downscaled. In this thesis, we detail the methods attempted towards the creation of this dataset to illustrate the complexity of this problem, from classical image processing techniques to deep learning and generative models. We present our initial classical method incorporating 3D face frontalization and normalization, as well as currently the most promising direction for the creation of this dataset: leveraging the state-of-the-art face image synthesizer StyleGAN with a consistency enforcing module to generate LR-consistent many-to-one HR/LR mappings. Our results show an initial formulation of DESRED with both high perceptual quality and diversity when compared with adjacent SR methods

Insertion and deletion tolerance of point processes
No full textWe develop a theory of insertion and deletion tolerance for point processes. A process is insertion-tolerant if adding a suitably chosen random point results in a point process that is absolutely continuous in law with respect to the original process. This condition and the related notion of deletion-tolerance are extensions of the so-called finite energy condition for discrete random processes. We prove several equivalent formulations of each condition, including versions involving Palm processes. Certain other seemingly natural variants of the conditions turn out not to be equivalent. We illustrate the concepts in the context of a number of examples, including Gaussian zero processes and randomly perturbed lattices, and we provide applications to continuum percolation and stable matching
“¿Simio divino o dios simiesco? El transhumano en Yuval Noah Harari”
No full textEste trabajo tiene el objetivo principal de tomar la cuestión del
transhumanismo para analizar, desde una posición filosófica, la obra del historiador
israelí Yuval Noah Harari. Con ello pretendemos acercarnos a la visión que tiene este
autor respecto a los beneficios y/o problemas que suscitan las aplicaciones de nuevas
tecnologías asociadas al biomejoramiento y las ingenierías informáticas, de manera que
podamos vislumbrar la posibilidad de que aparezca, en las próximas décadas o siglos, un
humano mejorado a través de la tecnología. Esta tarea la llevaremos a cabo en tres partes:
en primer lugar, realizaremos una exposición de las principales tesis filosóficas que
forman el ideario de Harari; en segundo lugar, veremos qué es el transhumanismo y
quiénes son sus principales acreedores; y, para acabar, nos acercaremos, con Harari, a los
problemas políticos, sociales y filosóficos de ese hipotético transhumano mejorado por la
tecnología, de modo que veremos la viabilidad que nuestro autor otorga a dichas teoríasThe main objective of this research is to take the issue of transhumanism to
discuss the work of Israeli historian Yuval Noah Harari from a philosophical perspective.
We intend to make an approach to the vision of this author about the benefits and
problems of the new technologies, associated to biological improvement and computer
engineering. In this way, we will be able to see the possibilities that the emergence of a
technologically improved human has. We will do this work in three parts: first, we will
expose the main ideas of Harari's philosophy; second, we will see what transhumanism is
and who its main authors are; and, finally, we will approach the political, social and
philosophical problems of this hypothetical technologically improved transhuman, and in
this way we will see the viability that Harari gives to these theories.Universidad de Sevilla. Grado en Filosofí
COMMUNICATION IN HOMO DEUS YUVAL NOAH HARARI
No full textOne of the elements that build human civilization is how to support the communication dimension in each stage of the civilization, even though the communication aspects are part of civilization itself. Therefore, studying a civilization, we are studying the dimensions of communication in that life. A work by an Israeli historian, Yoval Noah Harari, is the study of this article. Homo Deus, one of Harari's trilogy of masterpieces, has long been the subject of public discussion, containing many controversies that have later invited some debates. An unusual book because it can review almost all aspects of human life. Each focus of the study is reviewed from various dimensions. Examined with an unusual blend, scientific and social meet in one work. Although the content of this book is very comprehensive, the author only examines it from one dimension, namely the communication dimension. Studying this book gives us information that the civilization of communication goes hand in hand with human civilization. There is a reciprocal relationship between human civilization and the dimensions of communication. Communication develops because of the broad path provided by civilization, civilization develops because of the support of communication, and communication itself is part of that civilization. Then this relationship became crippled when communication devices, software and hardware, accelerated beyond human civilization itself.One of the elements that build human civilization is how to support the communication dimension in each stage of the civilization, even though the communication aspects are actually part of civilization itself.

Explicit SoS Lower Bounds from High-Dimensional Expanders
No full textWe construct an explicit and structured family of 3XOR instances which is hard for O(√{log n}) levels of the Sum-of-Squares hierarchy. In contrast to earlier constructions, which involve a random component, our systems are highly structured and can be constructed explicitly in deterministic polynomial time.
Our construction is based on the high-dimensional expanders devised by Lubotzky, Samuels and Vishne, known as LSV complexes or Ramanujan complexes, and our analysis is based on two notions of expansion for these complexes: cosystolic expansion, and a local isoperimetric inequality due to Gromov.
Our construction offers an interesting contrast to the recent work of Alev, Jeronimo and the last author (FOCS 2019). They showed that 3XOR instances in which the variables correspond to vertices in a high-dimensional expander are easy to solve. In contrast, in our instances the variables correspond to the edges of the complex
A Critique of Yuval Noah Harari’s _Sapiens: A Brief History of Humankind_
No full textThe foundational principles of representative democracy are under attack globally. What we desperately need are enlightened and persuasive public intellectuals who can help us see through the fog of our fear, anger, and disillusionment, to find our rational political commitments again. One of these public intellectuals is undoubtedly Yuval Noah Harari, the bestselling author of three recent books – Sapiens, Homo Deus, and 21 Lessons for the 21st Century. Harari is also a frequent contributor in the popular press, and a guest on shows, podcasts, panels, and as a keynote speaker. Add to all this that Harari is acting on his lofty academic ideals through ‘Sapienship’, a multidisciplinary organization he cofounded that advocates for global responsibility, clarifies the global conversation, and focuses attention on the most important global challenges. I single out Harari because I presume many readers will be familiar with his work. He is certainly one of the fastest rising stars of public intellectualism. Unfortunately, his work is undercut by the philosophical positions he put forth in his first bestselling book, Sapiens. In this review/critique I wish to show that in order for Harari advance a coherent political or ideological argument, he must first shore up his philosophical commitments
