Statistical machine learning for improved detection and uncertainty quantification of pathogenic E. Coli in hydroponic irrigation water using impedimetric systems
Reuse of alternative water sources for irrigation is a sustainable approach that can reduce water gaps, while increasing food production. However, when growing fresh produce, this practice increases the risk of bacterial contamination. Thus, rapid and accurate identification of pathogenic organisms such as E. coli is crucial for resource management. Dr. Nikolay Bliznyuk, a University of Florida associate professor of statistics, presented a statistical machine learning framework his team developed to predict and quantify uncertainty about E. coli concentration, which lets scientists quantify uncertainty about the bacterial concentration in a solution sample.

How would Fisher use genomic information to determine the genetic contribution to continuous traits?
In 1918, Ronald Fisher developed theory to demonstrate that under the assumption of Mendelian inheritance, one could determine the genetic contribution to continuous traits. In the absence of genomic information, he used pedigree relationships between individuals to determine the covariance between their genotypic values. In most of the current genetic analyses that utilize genomic information, the pedigree relationships are replaced by genomic relationships. In this talk, Rohan Fernando presented an alternative approach to study the genomic contribution to continuous traits that does not require making many of the usual assumptions such as random mating and linkage equilibrium.

AI Modeling of Soil Carbon from Local to Global Scale
Dr. Sabine Grunwald, a UF/IFAS professor of pedometrics, landscape analysis and geographic information systems in the UF/IFAS soil, water and ecosystem sciences department, talked about the optimization of soil carbon sequestration and reduction of land-based greenhouse gas emissions that are critically important for soil health, food security, carbon quantification and crediting, and resilient and sustainable agro-ecosystems. Whether soil carbon acts as a sink or source for carbon depends on multiple environmental factors that vary across spatial scales (field, regional, and global scale). Data- and sensor-driven approaches using machine learning and deep learning AI (artificial intelligence) have emerged as powerful force to model soil carbon dynamics and patterns in dependence of global climate change, crop types, land use management, and site-specific conditions. In this presentation prominent AI models to predict soil organic carbon and various carbon pools in Florida, the U.S. and at global scale are presented. Critical discussion focused on model accuracy, actual vs. attainable (optimized) soil carbon, and spectral and spatial resolutions of sensors needed to support local land management as well as regionalized carbon accounting, policies, and marketing.

He also identified important opportunities for AI and machine learning in hydrology.
Data Ethics in AI Development and Implementation in Agriculture
Given legal limitations, defining data as a property that can be owned is a tricky and difficult process, especially for farmers. Big companies, with professional legal teams, have already created aggressive contractual terms to protect their rights and obligations. However, farmers, lacking related knowledge and skills, may not realize the problem or, even if they do, may not know how to react. Recent efforts indicate that interpreting data rights from contractual terms is challenging. In his presentation, Dr. Ziwen Yu, a UF/IFAS assistant professor of agricultural and biological engineering, explained key elements regarding the protection of data rights, leveraging data value, and recognizing emerging data-derivative markets.
