Friday, April 25th 12:00pm - 1:00pm, Zoom/ARB 627 Meeting ID: 957 7525 9475 Passcode: 834911 Minghe Wang MS in Biostatistics Student Columbia University Understanding and Addressing Covariate Shift in Transfer Learning Part 2 Abstract: Building on the foundational concepts of covariate shift problem introduced in the first lecture, this session will explore advanced covariate shift adjustment methods that estimate importance weights as a whole rather than separately. We will cover Kernel Mean Matching, Kullback-Leibler Divergence Minimization, and Least-squares-based techniques. These methods offer improved stability and efficiency in high-dimensional settings, making them especially relevant for modern healthcare datasets. The lecture will include hands-on examples to illustrate how these approaches can be implemented and evaluated in practice. By the end of this session, participants will be more familiar with covariant shift problem and the application of importance weighting methods. Speaker Bio: Minghe Wang is a first-year Master's student in Biostatistics. He received his Bachelor's degree in Applied Mathematics, with a minor in Computer Science, from New York University. He will be leading the lectures and labs for this series of tutorials, under the mentorship of Drs. Tian Gu and Ying Wei. About TRAIL4Health & the Brown Bag Learning Series TRAIL4Health is a Translational AI Laboratory committed to advancing public health through innovative applications of artificial intelligence and data science. At TRAIL4Health, we host a variety of events to foster learning, collaboration, and the exchange of ideas at the intersection of AI, public health, and medicine.  The TRAIL Brown Bag Learning Series is a weekly informal gathering held on Fridays at noon in Room 627 of the Allen Rosenfield Building. These sessions are an opportunity for faculty, students, and researchers to come together and learn something new—whether it be a dataset, software, new article, or simply to exchange ideas. This informal setting provides a platform for sharing knowledge, stimulating discussions, and fostering collaboration in a relaxed environment. 

On April 28, Mariah DeSerisy is presenting, "Environmental Influences on Brain Connectivity and Children’s Mental Health." Catherine Lucey is presenting, "Human Relevant Doses of Arsenic and Uranium in Drinking Water Minimally Exacerbate Cardiometabolic Phenotypes in ApoE-/- Mice." Join us in person in ARB 1101 or via Zoom. In-person attendance is only available to Columbia affiliates. Affiliates outside of Columbia are welcome to attend via Zoom.

Catalyzing change in next-gen health requires a shift in focus toward areas with the greatest potential for long-term impact, such as women’s health and emerging technologies. These fields offer powerful opportunities to improve health outcomes, drive innovation, and address longstanding gaps in care. By supporting new ideas and expanding access to overlooked areas of health, we can build a more inclusive and forward-looking future - one where innovation is guided by equity, science, and the needs of diverse communities. The program is a one-of-kind multi-disciplinary discussion and educational experience that brings the greatest minds from medicine, science, venture capital, capital allocation, business, and operations together to solve pain points of critical healthcare areas that require innovation. This event not only provides an overview of the healthcare innovation landscape, but also provides insight on the know-how or barriers in commercialization and scaling of health innovation across the U.S. SPEAKERS Lily Jin (Moderator), Operating Partner, Marathon Venture Partners Camilla Languille, Co-Chief Executive Officer, Mubadala Private Equity Charlotte Xia, Investor, Fusion Fund

Over the summer and fall of 2024, ICAP supported 18 students from Columbia Mailman School of Public Health and the Fu Foundation School of Engineering and Applied Sciences in completing their required practica. Students engaged in projects ranging from HIV intervention evaluations, digital interventions in decreasing stigma around pre-exposure prophylaxis, and exploring the impact of climate change on HIV and other infectious diseases. Join us in celebrating the students’ accomplishments as they share their work and their contributions to ICAP’s mission to strengthen  global health. ICAP’s Next Generation Program is a multidisciplinary training initiative that provides students with internship and fellowship opportunities focusing on global public health.
