Previous to data fusion it is important to establish the relative importance (weights) of each variable (chemical space coordinates, i.e., t-SNE coordinates) to describe the studied data (chemical structures associated with DILI reports). For this reason, we propose a simple metric, Quadrant weight (QW) -Equation , that allows uncovering specific regions on the chemical spaces (2D plot coordinates) that are enriched with compounds associated with DILI events:
