Generating experimental toxicity data is\, however\, re source-intensive and time-consuming. Computational methods are fast and co st-efficient alternatives\, but the low accuracy and narrow applicability domains have made their adaptation slow. In this presentation\, we will le arn the basics of chemical hazard assessment\, talk briefly about cheminfo rmatics\, and finally build intuition for why transformers are suitable mo dels for capturing the complex chemical and biological interactions necess ary for accurate toxicity prediction. Finally\, we will look at some resul ts from our recent publication\, demonstrating how transformers capture to xicity-specific features directly from the chemical structures themselves. \n LOCATION:https://researchseminars.org/talk/gbgphd/4/ END:VEVENT END:VCALENDAR
