Machine Learning Applied to the Detection of Mycotoxin in Food: A Review

no code implementations23 Apr 2024 Alan Inglis, Andrew Parnell, Natarajan Subramani, Fiona Doohan

Mycotoxins, toxic secondary metabolites produced by certain fungi, pose significant threats to global food safety and public health.

SERT: A Transfomer Based Model for Spatio-Temporal Sensor Data with Missing Values for Environmental Monitoring

1 code implementation5 Jun 2023 Amin Shoari Nejad, Rocío Alaiz-Rodríguez, Gerard D. McCarthy, Brian Kelleher, Anthony Grey, Andrew Parnell

We propose two models that are capable of performing multivariate spatio-temporal forecasting while handling missing data naturally without the need for imputation.
