Understanding Risk Extrapolation (REx) and when it finds Invariant Relationships
No full textGeneralizing models for new unknown datasets is a common problem in machine learning. Algorithms that perform well for test instances with the same distribution as their training dataset often perform severely on new datasets with a different distribution. This problem is caused by distributional shifts between the training of the model and applying that model to a test domain. This paper addresses whether and in what situations Risk Extrapolation (REx) can tackle this problem of Out-Of-Distribution generalization by exploiting invariant relationships. These relationships are based on features that are invariant across all domains. By learning these relationships, REx aims to learn the concept of the problem we are trying to solve. We show in what situations REx can learn these invariant relationships and when it does not. We translate the definition of an invariant relationship into a homoscedastic synthetic dataset with either covariate, confounded, anti-causal, or hybrid shift. We expose REx to experiments in sample complexity, the number of training domains, and the training domain distance. We show that REx performs better for invariant prediction in situations with larger sample sizes and training domain distance and that if these criteria are met, REx performs equivalently in all four distributional shifts. We also compare REx to Invariant- and Empirical Risk Minimization and show that; REx is less sensitive and thus robust to the shifting of the average distributional variance in the training domains; REx asymptotically out-performs the methods in the more complex distributional shifts.https://gitlab.com/hofland.jeroen/rex-distributional-shift CodeCSE3000 Research ProjectComputer Science and Engineerin

Blood and Beauty: Organized Violence in the Art and Archaeology of Mesoamerica and Central America
No full textWarfare, ritual human sacrifice, and the rubber ballgame are the traditional practices through which scholars have most often examined organized violence in the artistic and material records of ancient Mesoamerica and Central America.This volume expands them to include such activities as gladiatorial-like boxing combats, investiture rites, trophy-head taking and display, dark shamanism, and the subjective pain inherent in acts of violence. Each author examines organized violence as a set of practices grounded in cultural understandings, even when the violence threatens the limits of those understandings. The authors scrutinize the representations of, and relationships between, different types of organized violence, as well as the implications of those activities. These can include the unexpected, such as violence as a means of determining and curing illness, and the use of violence in negotiation strategie
The Ancient Colors in the Public Art of Tenochtitlan
No full textThe goal of my research was to explore the significance color held in Aztec public art found at Templo Mayor in the city of Tenochtitlan. By studying the coat of paint the monoliths had been covered with in the past, I hoped to discover how color enhanced the experience and meaning of key rituals done in relation to the public art. This research was done to help the public understand how the Aztec's religious beliefs influenced their art and why they expressed it with color. My key source was the 2017 Templo Mayor Museum article “Nuestra Sangre, Nuestro Color: La escultura polícroma de Tenochtitlan'' by Leonardo López Luján which directly speaks on the science behind the new color research for monoliths. However, my project heavily relied on the research done by Diana Magaloni in her book “The Colors of the New World” where she takes a closer look at the Florentine Codex illustrations that reveal to us the indigenous paint-making process. Through my investigation I determined that the significance color has in Aztec art, from their drawings to their monoliths, is based on what raw materials were used and where they originate from. The paints can be categorized into two groups, those made from organic materials which then symbolize the masculine solar world, or pigments that are telluric and are associated with the feminine underworld. The Aztecs would choose which paints to use based on this significance to represent different elements of their religion through their art.Honors CollegeArt, School o
Idols behind Altars – Revisited: Examining the Construction of the Mexican Artistic Identity through Visual Culture and Folk Art in the United States
No full textThis thesis examines the post-revolutionary creation of Mexican visual identity in the U.S. Focusing on the role of Idols Behind Altars by Anita Brenner, and her use of photography and text that attempt to frame the visual idea of Mexico for audiences of the early 20th century. Brenner places a specific emphasis on folk art as a way of understanding the prevalence of Mexican culture and identity, which I examine in three major exhibitions of the early 20th century. Brenner is seen as an intellectual of this movement, especially as critical translator of Mexican cultural ideals. She served as anthropologist, journalist, art historian, art critic, and worked as an advocate for Mexican culture and arts – especially for its representation in the United States. In constructing an understanding of the author and the inception of the book gives way for interpreting how folk art is part of the Mexican identity.Art, School o
