Joint Computer Science + Statistics Colloquium – Mathematics & Statistics

Joint Computer Science + Statistics Colloquium: Mike Baiocchi '03 and Jordan Rodu '05 Tuesday, October 31st @ 7:00pm in Wege  ***Stats Colloquium credit for attendance and Spooky Snacks provided!*** Outcome Reasoning: the under-discussed engine powering black box algorithms We’ll start this talk discussing a couple of studies: (i) a randomized trial to evaluate a sexual assault prevention program in Nairobi, Kenya and (ii) a remote detection operation to find and disrupt labor trafficking in the Amazon rainforest. These are both “data science” projects but they are wildly different in how they work. What makes them so different? For a long time in (bio)statistics we only had two fundamental ways of reasoning using data: warranted reasoning (e.g., randomized trials) and model reasoning (e.g., linear models). In the 1980s a new, extraordinarily productive way of reasoning about algorithms emerged: “outcome reasoning.” Outcome reasoning has come to dominate areas of data science, but it has been under-discussed and its impact under-appreciated. For example, it is the primary way we reason about “black box” algorithms. In this talk we will discuss its current use (i.e., as “the common task framework”) and its limitations. We will show why we find a large class of prediction-problems are inappropriate for this new type of reasoning. We will then discuss a way to extend this type of reasoning for use, where appropriate, in assessing algorithms for deployment (i.e., when using a predictive algorithm “in the real world”). We purposefully developed this new framework so both technical and non-technical people can discuss and identify key features of their prediction problem. Mike Baiocchi ’03 Pronunciation: bye-oh-key Professor Baiocchi considers himself an interventional statistician (i.e., grounded in both the creation and evaluation of interventions). He thinks a lot about behavioral interventions and how to rigorously evaluate if and how they work. Methodologically, he…

Visiting Assistant Professor of Mathematics – Mathematics & Statistics

The Williams College Department of Mathematics and Statistics invites applications for a one-year visiting position in mathematics, to begin fall 2024. Candidates should have earned a Ph.D. in mathematics or applied mathematics by summer of 2024. Visiting Assistant Professors are asked to teach four courses per year and make small contributions to service activities in the department. Furthermore, they will be invited to participate in all aspects of the department, providing a window into the experience of being a mathematician in a liberal-arts college. For example, should they wish to, a VAP could advise undergraduate student colloquia (our capstone experience for seniors) or participate in SMALL, our NSF-funded REU summer program. Our department offers a vibrant undergraduate program with majors in mathematics (including an applied mathematics emphasis) and statistics; for more information, see https://math.williams.edu. The multidisciplinary environment is a rich and collegial setting for student education and faculty research. Williams College provides the opportunity to apply for student research assistant support, an annual allocation of funds to support travel and research, and a shared computer cluster for parallel computation. Williams offers faculty participation in the college’s professional development program First3, access to a number of online NCFDD resources, and support through the newly established Rice Center for Teaching. Williams has an enrollment of approximately 2000 undergraduates, roughly 15% of whom major in mathematics and statistics. Our department is a warm community of mathematicians and statisticians who are deeply dedicated to research, teaching, and mentoring undergraduates, and are committed to making everyone feel welcome and included. We encourage all applicants who are driven by both research and teaching to apply.   Approximately one hour from the Albany, NY airport, Williams College is located in Williamstown, a thriving destination proximate to three major art museums and access to theater, music, and dance…

This year, the department’s summer research opportunities are all through SMALL. Project titles are listed below, and project descriptions may be found on the SMALL website. Mathematics:  Ralph Morrison, “Chip-Firing Games on Graphs”  Jenna Zomback and Austyn Simpson, “Commutative Algebra: Interactions with Logic”  Prerequisite: abstract algebra  Susan Loepp, “Commutative Algebra: Local Rings and Completions” l Prerequisite: abstract algebra  Steven Miller, “Number Theory and Probability”  Statistics:  Xizhen Cai, Anna Plantinga, and Elizabeth Upton, “Statistical Approaches to Pattern Matching in Forensic Evidence”  Prerequisite: a course in regression methods (STAT 346 or equivalent)  Applications for SMALL are due by Wednesday, February 1.  Senior Theses In addition to summer research, junior majors are invited to apply to undertake a senior honors thesis or mini-thesis. Many faculty in the department advise thesis students; stay tuned for an informational event and application form in early April, and feel free to chat with faculty about their research and thesis projects in advance.  Other Research During the Semester Outside of theses and mini-theses, occasionally students who have the requisite background engage in faculty-advised research during the semester, either informally or as Research Assistants. Feel free to reach out to faculty about this possibility. Note: Research opportunities (summer, thesis, and otherwise) with different faculty members may require different course prerequisites; feel free to reach out to faculty for details.

Colloquiumfest and Pizza Lunch on Thursday, January 19th – Mathematics & Statistics

On Thursday, January 19th, we'll be holding our Mathematics Colloquiumfest!  This will feature multiple colloquia being presented in parallel sessions both in the morning and the afternoon; see below for the full schedule.  For junior and senior math majors, this is a great opportunity for you to get multiple colloquium credits in one day (as many as 6)!  There will also be a pizza lunch in the Frank Morgan Math/Stat Library from 11:45am to 1pm, open to anyone attending any of the talks. Here's a detailed schedule, including speakers, titles, abstracts, rooms (all in Wachenheim), and times: 9:30a.m. Room 114 Petros Markopoulos The Axiom of Choice and Equivalent Statements Mathematician Jerry Bona said: “The Axiom of Choice is obviously true, the well-ordering principle obviously false, and who can tell about Zorn’s lemma?” but they are all equivalent statements. In this talk, we will first discuss the statements and some of their consequences and present a proof of their equivalence. 10:15a.m. Room 017 Will McCormick A Hemispherical Basis for Efficient Rendering Reflectance Transformation Imagery (RTI) is a form of texture mapping with the possibility of interacting to change an image’s light direction. This powerful tool has improved the studies of ancient writings, inscriptions, and more. This talk discusses the two algorithms developed for RTI: Hemispherical Harmonics Mapping (HSH) and its predecessor, Polynomial Texture Mapping (PTM). Throughout this discussion, we will uncover why HSH is often preferred in modern-day practice over PTM. 10:15a.m. Room 114 Brandt Mandia Predicting MLB win-loss records by Run Scored vs Runs Allowed Bill James empirically discovered a good predictor of a team's winning percentage is RS^2 / (RS^2 + RA^2), where RS is the average number of runs scored per game, and RA the average number allowed. We discuss a derivation of this result using techniques from…
