It provides a platform to train and evaluate ML classification models on any tabular data without requiring any programming background. Users can simply upload their dataset to the site, choose the training parameters, and the job will be sent off to train all chosen models and provide results in the form of tables and visualizations. CLASSify also provides options for synthetic data generation to bolster imbalanced class labels or create entirely new datasets, as well as explainability scores that provide insight into which features of…

September 19, 202412:15 pm Speaker:Brent Harrison, Computer Science, University of Kentucky Where:327 McVey Hall(Zoom link: https://uky.zoom.us/j/82467171189) Title:Practical Value Alignment Using GPT-4o Abstract: As artificial intelligence (AI) and machine learning (ML) systems grow in power, their risk of causing unintentional harm grows. This is because often these systems are optimizing for criteria that is different than our own, often meaning that it does not consider the many social and cultural norms that we implicitly and explicitly use when making decisions. In a value-aligned system, however, system behavior and objectives are aligned with expected human sociocultural norms. Creating a value-aligned system, however, can be difficult as sources of explicit value information are scarce. In this tutorial, I will discuss how large language models, specifically GPT-4o, can be used to perform practical value…

September 12, 202412:15 pm Speaker:Brent Harrison, Computer Science, University of Kentucky Where:327 McVey Hall(Zoom link: https://uky.zoom.us/j/82467171189) Title:A Gentle Introduction to Modern Machine Learning Abstract: Machine learning has rapidly grown over the last few years. Currently, there are many elements of our social and work lives that utilize, in some way, a machine learning system. To better utilize these systems, it is important to understand how these systems work. In this talk, I will provide an overview of machine learning systems to provide a foundation that the other talks in this series can build on. I will focus on high-level details of how these systems work, how they're often used in practice, and their data requirements. Click here to see the complete list of speakers.

Hardymon Theatre(Zoom link: https://uky.zoom.us/s/84474671604) Title:Cosmology via big data in Astrophysics  Abstract: State-of-the-art observational surveys such as the one carried out by the EUCLID mission, BOSS, DES and forthcoming ones like LSST, HETDEX among others, will cover of the order of 10000 square degrees on the sky, with the primary science goal to unravel the nature of the physics responsible for the current accelerated expansion of the universe. The unprecedented and rich data provided by these surveys will make it possible to investigate fundamental physics (e.g. inflation, neutrino properties) and astrophysics (e.g. biasing, galaxy formation). The success of future large-scale galaxy surveys evidently requires a correct interpretation…
