The AfterMath of an Extreme Natural Event
presented by Linda Smolka, Professor of Mathematics, Bucknell University

ABSTRACT: An astonishing thing happened on January 15, 2022. The Hunga Tonga-Hunga Ha’apai submarine volcano located in the South Pacific Ocean erupted, becoming the largest volcanic eruption in the modern satellite era on a scale not observed since Krakatoa erupted in 1883. The eruption was so powerful that among the shock waves it generated, the largest traversed the globe multiple times over several days. We’ll focus on the mathematics to model and understand this shock wave and also recount other extraordinary phenomena in the eruption’s aftermath. Curious where calculus is used in the real-world? Come see.

“LSH Schemes (and how to improve them)”, Bucknell Machine Learning Association (MLA) Talk by Prof. Keegan Kang Monday Sept. 5 at 5.45pm at in the Traditional Reading Room (BERT 213).

The Bucknell MLA will hold its first meeting on Monday 9/5 at at 5.45pm in the Traditional Reading Room (BERT 213), for members to get to know each other and share their passion for machine learning. Prof. Keegan Kang will give an introductory talk on LSH Schemes.

ABSTRACT: There are some challenges with traditional machine learning in a Big Data world. Locality Sensitive Hashing (LSH) schemes are able to mitigate some of these challenges. The idea of LSH schemes will be briefly introduced in this talk by looking at an example of them: sign random projections. This will be followed briefly by an illustration of how LSH schemes can be improved, before concluding with several fun research areas using these schemes.
