Bayesian Hierarchical Change-Point Model for Pitcher Biomechanics
Rose Graves
Rice University


Abstract: The rise of pitcher injuries in Major league Baseball the past decade has become an
epidemic. The defining questions around pitcher injuries have turned from prevention to
treatment and management. Determining the factors that are impacting pitcher health is
essential in ensuring the longevity of the sport and the well-being of its players. One of the
hypothesized factors behind these concerning trends is pitching while fatigued. Starting
pitchers often throw at high velocities for several innings and fatigue leads to changes in
performance. We implement a novel hierarchical Bayesian change-point model to identify
trends in the changes of a pitcher’s pitch characteristics and biomechanics over the course of
multiple games throughout the season. Each player is unique in the types of pitches they throw,
their biomechanics, and how they fatigue. Our hierarchical framework allows us to capture
these differences between pitchers in terms of locations of when their mechanics change and
the slopes of the trends before and after the change-point during an outing. The model sets a
baseline for players and allows teams to identify abnormal changes. We examine
velocity, horizontal and vertical movement, throwing shoulder abduction and external rotation,
and torque applied to trunk and upper arm. Our model allows us to develop a robust
understanding of physical changes in a player’s mechanics and pitch characteristics throughout
a game.

Mathematics major, Logan Abounader will give a talk titled Prime Graph Complements of A11 and A13 Solvable Groups
TalkMath2Me is a seminar for students and by students organized by Pi Mu Epsilon. Talk Math 2 Me provides students, both graduate and undergraduate, an opportunity to present anything related to mathematics to an audience of their peers. The talks can be 15-90 minutes long. Past topics have included talks on impressive student research, famous mathematicians, sports, puzzles and games, and time travel!

The Mathematics Classroom: A Refuge for Reason.

Abstract: Generative AI poses an epistemic threat to our society. Models trained on millions of pages of written records appear to be experts across more domains than any person could hope to become. From there, it is a short step for students to conclude that expertise is no longer a goal worth the effort, and that working through a problem takes too long when the work can simply be offloaded to a chatbot. This misses the point. Mathematical knowledge is not a set of retrievable answers but a lens for viewing the world that unlocks access to science, engineering, medicine, public policy, and the social sciences. 

Active learning is usually billed as a research-backed pedagogy that improves student outcomes. It is much more than that. It is an instantiation of our values: that students learn mathematics by doing mathematics, and that mathematical reasoning is an internal process each student must take up for themselves. Homework used to provide the incentives and environment that encouraged students to practice reasoning, but now it can be completed with help from Claude. Instructors face a new imperative to get students thinking during class. 

I will share what the research literature says about the value of active learning, along with methods I use to make my own classes more engaging.

Title: Using Local Data to Guide a Calculus Program: Six Cases from Harvard

ABSTRACT
The MAA's National Study of College Calculus identified seven characteristics of successful calculus programs. This talk takes up the one that depends on coordination across instructors, administrators, and mathematics education researchers: using local data to guide curricular and structural change.

This work requires consistent and innovative data collection, enough command of the research literature to read that data through, and familiarity with the whole ecosystem of the calculus program. It is not itself research, but it is driven by a researcher’s expertise, which keeps curricular and structural choices aligned with what the field already knows.

I will describe the shape of this work at Harvard through six examples:
  • a live grade dashboard that flags students for early intervention
  • a qualitative study of how students choose their first math course
  • an assessment of our summer bridge program
  • an audit of the placement exam, and the strategies we built from it to route students into the right first course
  • a study of how instructors develop a sense of narrative in their teaching
  • a randomized controlled trial of AI assistance on problem sets
I'm looking forward to sharing the work with an audience considering more coordination across courses and with such deep expertise in mathematics education.
