"Vulnerabilities of Data Analysis: From Political Spin to Data Manipulation" presented by Scott Alfeld
The Faculty Colloquium Series for 2019-20 presents a lecture titled "Vulnerabilities of Data Analysis: From Political Spin to Data Manipulation" presented by Scott Alfeld, assistant professor of computer science.
Learn how to bypass a state-of-the-art security system with sugar cubes and a slingshot. New security vulnerabilities have arisen with the growing use of machine learning in decision-making systems. In this talk I discuss the field of Adversarial Learning — the study of using machine learning techniques when the input data may be corrupted by an attacker. I’ll cover various techniques hackers employ and defenses again them. We'll then get our hands dirty attacking a learner at training time and see what finesse is needed when manipulating even the simplest of learners.
Faculty Colloquium events are sponsored by a group of faculty colleagues who meet informally with the purpose of supporting and promoting the College’s commitment to faculty research. Colleagues interested in joining this endeavor are welcome and should contact us by email: email@example.com . Faculty, staff, and members of the administration are cordially invited to attend these presentations.

In the same 1950 article in which Alan Turing described his “imitation game” test for artificial intelligence, he also described ways in which ideas from evolutionary biology might help us to develop AI. It took time for these ideas to be refined, and it took advances in computing infrastructure for them to bear fruit, but now “evolutionary computation” methods are solving scientific and engineering problems that are beyond the reach of other forms of AI.
In this talk, Spector will introduce the general concepts of evolutionary computation and illustrate some of its applications. He will also describe a contribution to the field that he and his students have recently made, demonstrating that the speed and success of adaptation can be boosted by using random sequences of challenges, rather than overall performance, as the basis for parent selection in evolving populations. This approach increases the problem-solving power of evolutionary computation, and it also raises broader questions about the role of specialists in communities and in evolution.

Science and the technologies it has spawned have been the principal drivers of the American economy since the end of World War II. Today, economists estimate that a whopping 85 percent of gross domestic product (GDP) growth traces its origin to science and technology. The size of the impact should not be a surprise, considering the ubiquity of modern technologies.
Innovation has brought us the consumer products we take for granted: smartphones and tablets, CD and DVD players, cars that are loaded with electronics and GPS navigating tools and that rarely break down, search engines like Google and Yahoo, the Internet and the Web, money-saving LED lights, microwave ovens and much more. Technology has also made our military stronger and kept our nation safer. It has made food more affordable and plentiful. It has provided medical diagnostic tools, such as MRIs, CT scanners and genomic tests; treatments for disease and illness, such as antibiotics, chemotherapy, immunotherapy and radiation; minimally invasive procedures, such as laparoscopy, coronary stent insertion and video-assisted thoracoscopy; and artificial joint and heart valve replacements.
None of those technological developments were birthed miraculously. They owe a significant part of their realization to public and private strategies and public and private investments. Collectively the strategies and investments form the kernel of science and technology policy. "Navigating the Maze" is a narrative covering more than 230 years of American science and technology history. It contains stories with many unexpected twists and turns, illustrating how we got to where we are today and how we can shape the world of tomorrow.
The Book of Job, regarded by some as the greatest poem ever written, has been misunderstood in many details and in some of its major themes and thrusts. E.L. Greenstein’s new translation of Job draws on decades of painstaking work on the language, argument and poetics of the book. In this lecture, Greenstein will explain how he has sought to change our understanding of Job on both the micro and the macro levels. Edward L. Greenstein is professor emeritus of biblical studies at Bar-Ilan University, Israel, and a prolific, world-renowned scholar in many areas of biblical and ancient Near Eastern studies.

Nicholas A. Christakis, M.D., Ph.D., M.P.H., is a sociologist and physician who conducts research in the areas of social networks and biosocial science. He directs the Human Nature Lab. His current research is mainly focused on two topics: (1) the social, mathematical and biological rules governing how social networks form (“connection”), and (2) the social and biological implications of how they operate to influence thoughts, feelings and behaviors (“contagion”). His lab uses both observational and experimental methods to study these phenomena, exploiting techniques from sociology, computer science, biosocial science, demography, statistics, behavior genetics, evolutionary biology, epidemiology and other fields.
The Point/Counterpoint series is based on a course of the same name. The course and associated event series received special funding through a generous gift from 36 members of the 50th Reunion Class of 1970.
What is the maximum number of edges in a graph on n vertices without triangles? Mantel’s answer in 1907—that at most half of the edges can be present—started a new field: extremal combinatorics. More generally, what is the maximum number of edges in an n-vertex graph that does not contain any subgraph isomorphic to H? What about if you consider hypergraphs instead of graphs? I will introduce the technique of sums of squares and discuss how it can be used to attack such problems.
Holly Jackson, associate professor of English at the University of Massachusetts Boston, will read from her new book, American Radicals: How Nineteenth-Century Protest Shaped the Nation (Crown, 2019).
On July 4, 1826, as Americans lit firecrackers to celebrate the country’s 50th birthday, both John Adams and Thomas Jefferson were on their deathbeds. They would leave behind a groundbreaking political system and a growing economy—as well as the glaring inequalities that had undermined the American experiment from its beginning. The young nation had outlived the men who made it, but could it survive intensifying divisions over the very meaning of the land of the free?
“In the tradition of Howard Zinn’s people’s histories, American Radicals reveals a forgotten yet inspiring past.” —Megan Marshall, Pulitzer-Prize–winning author of Margaret Fuller: A New American Life and Elizabeth Bishop: A Miracle for Breakfast
Fueled significantly by a growing Latinx population, the racial/ethnic and linguistic texture of the United States continues to change. Despite their increased presence, Latinx students from K-12 through college continue to be underserved by schools. Foregrounding the oft-silenced perspectives of Latinx students, this presentation critically examines the challenges they face navigating educational institutions that rarely, if ever, affirm and more often ignore or malign their identities. It highlights students’ struggles for survivance—ways of recovering, bolstering and sustaining their cultural identities—and pursuit of equitable educational opportunities, concluding with empirically based strategies for improving the educational experiences and outcomes for Latinx students.
“Secular Chapel: What Greta Thunberg Means to Me” is a gathering for Amherst College students, faculty and staff hosted by Professors Jen Manion and Michael Kunichika and choir director, Professor Martha Umphrey. There will be a light reception. For inspiration and more information, see link below.
Despite three decades studying superconductivity in cuprate-based materials, we are still left with an incomplete understanding of how their superconducting state at unexpectedly high temperatures emerges from a “soup” of multiple broken-symmetry phases (i.e. ordered states). Although states of broken translational symmetry (i.e. charge order) were known to exist in some cuprates, only recently have we realized [1,2] that charge order could be the missing piece of the high-Tc puzzle. To understand how charge order fits in the puzzle, we require a suite of new measurements to specifically address: What does the charge order ‘look’ like? Is the charge order, like superconductivity, ubiquitous to all cuprates or just a material-specific accident? Is it helpful or harmful to superconductivity? Which electronic orbitals form the ordered patterns? Is it related to the mysterious pseudogap phase? Do the electron spins participate in the charge order phenomenon?
In this talk, I will discuss how we pushed the limits of scanning tunneling microscopy and spectroscopy (STM/S) and resonant (inelastic) x-ray scattering (R(I)XS) to address some of these questions [2-5]. In particular, I will focus on how STS can be used to ‘take pictures’ of charge order patterns with atomic resolution in solids and how soft RXS has emerged as an extremely sensitive technique to detect charge order in quantum materials.

Abstract: A key question in machine learning research is understanding the trade-off between the size of the training set and the accuracy of the classification function learned by the algorithm. This trade-off can be fully characterized by a single quantity: the VC-dimension of the family of functions that the algorithm may learn. Beautifully combinatorial in nature, the VC-dimension is elusive to compute exactly, but upper bounds to it are sufficient to understand the trade-off. In this talk, we report on our recent results on improved upper bounds to the VC-dimension of intersections of half-spaces in high dimensions, a very popular class of functions. We show a novel connection with convex polytopes and with planar graphs. All the terms and results will be explained without assuming any specific background in the audience.
Refreshments will be served at 3 p.m. in Science Center C209.
This lecture has been cancelled.

The digestive tracts of sharks and skates provide a fascinating model for studying the evolution of morphological asymmetries. Unique to all basal fishes is the spiral intestine, which may represent an intermediate morphology in evolution from the straight gut of lamprey to the elongated coils of higher vertebrates. The short spiral allows for a large absorptive surface area that can fit into a restrictive abdominal cavity. My lab is exploring how the spiral intestine forms during development of the little skate and the radial constraints that propagate spiraling.

We normally think of large accelerators and massive detectors when we consider the frontiers of elementary particle physics, pushing to understand the universe at higher and higher energy scales. However, several tabletop low-energy experiments are positioned to discover a wide range of new physics beyond the Standard model, where feeble interactions require precision measurements rather than high energies. In high vacuum, optically levitated dielectric nanospheres achieve excellent decoupling from their environment, making force sensing at the zeptonewton level (10-21 N) achievable.
In this talk, I will describe our progress towards using these sensors for tests of the Newtonian gravitational inverse square law at micron-length scales. Optically levitated dielectric objects and optical cavities show promise for a variety of other applications, including searches for gravitational waves and dark matter. Finally, I will discuss the Axion Resonant InterAction Detection Experiment (ARIADNE), a precision magnetometry experiment using laser-polarized 3-He gas to search for a notable dark-matter candidate: the QCD axion.
