The Full Event Interpretation is an algorithm which applies supervised learning to the task of reconstructing tag-side B mesons at Belle II. In a hierarchal manner, the algorithm trains of order 200 Boosted Decision Trees, which are each tasked with the identification of individual particle decay channels within the decay chains of B mesons. This seminar presents the algorithm and recent efforts to quantify its performance on the Belle legacy dataset and the first Belle II data. In addition, a recent first analysis using the algorithm to search for B+→l+ nu gamma decays is presented.
