SUMMARY:Gabe Chandler (Pomona College)
DESCRIPTION:Title: Graphical Anomaly Detection for High Dimensional and Object Data \nAbstract: Anomaly detection is an important task in data analysis\, though an agreed upon definition of what constitutes an outlier does not exist.  Accordingly\, a graphical tool that can highlight interesting observations in a data set that the scientist can then investigate with domain specific knowledge would be of value.  The depth quantile function (DQF)\, a recently introduced feature map that takes data of arbitrary dimension to a function of a single variable while encoding certain geometric information\, will provide such a tool.  After introducing the DQF\, we will discuss adaptations that make it particularly suited to the problem of anomaly detection\, particularly the case where the non-anomalous data is living on a lower dimensional manifold in the data space.  The DQF is also kernelizable\, allowing applications to non-Euclidean data\, as will be demonstrated via several examples.

SUMMARY:Homological mirror symmetry\, curve counting\, and a classical example: 27 lines on a nonsingular cubic surface (Reggie Anderson\, CMC)
DESCRIPTION:Though mirror symmetry requires much technical background\, it gained traction in the mathematical community when physicists Candelas-de la Ossa-Green-Parkes discovered enumerative invariants counting the number of rational degree d curves inside of certain space called a “quintic threefold.” This answered longstanding problems in enumerative geometry from antiquity. In particular\, the number of rational degree d=1 curves inside of the space counts the number of lines. We will review a simpler\, classical example: any nonsingular cubic surface contains exactly 27 lines.

SUMMARY:Claremont Topology Seminar: Adam Yassine (Pomona College)
DESCRIPTION:We welcome all undergraduates and graduate students to attend topology seminar! \nSpeaker: Adam Yassine (Pomona College) \nTitle: A Structural Approach to Classical Mechanics \nAbstract: A structural approach to the study of classical mechanics clarifies the physical heuristics that physicists use in constructing mathematical models of classical mechanical systems. The focus of our current program is to develop a category theoretic framework that captures certain compositional features of classical mechanics. The framework is both flexible enough to support the description of a wide variety of systems and rigid enough to uniquely determine the physicists’ models.

SUMMARY:Teaching Equity-minded Active Mathematics: A model for Instructional Change (Amelia Stone-Johnstone\, CSU Fullerton)
DESCRIPTION:Title: Teaching Equity-minded Active Mathematics: A model for Instructional Change \nSpeaker: ​Amelia Stone-Johnstone\, Department of Mathematics\, California State University\, Fullerton \nAbstract: Active learning has been championed as a mechanism for greater student learning and participation in STEM. However\, recent studies have demonstrated how active learning without an explicit equity focus may harm students from historically marginalized communities in STEM. In this talk\, I will introduce a model for professional development that attends both to equity and active learning. In addition\, I will introduce the Teaching Equity-minded and Active Mathematics (TEAM) Tool\, a tool for pedagogical reflection that was developed by a team of undergraduate students at California State University\, Fullerton. This research-backed tool was constructed as a way to support faculty in creating a learning atmosphere in which students can explore\, discuss\, and learn mathematics in the classroom in a safe\, just\, active\, and equitable manner. \n\n\n\n\n\nAmelia Stone-Johnstone is an Assistant Professor in the Mathematics Department at California State University\, Fullerton. Her research involves the development and assessment of academic support systems in introductory mathematics courses. In addition\, Dr. Stone-Johnstone’s research and service include faculty professional development on equity-minded instruction.
