Visualization of the 30th decision tree from a USMILE customized classifier; each classifier contains 100 decision trees, with 400 classifiers trained in total. Each split evaluates a single color feature against a threshold, branching into two possible paths: a default direction (blue) and an alternative direction (red). Two example regions of the tree are shown, where “iy,” “zy,” “yj,” “yh,” “yk,” “yw1,” and “yw2” correspond to the i_LSST − y_LSST, z_LSST − y_LSST, y_LSST − J_VHS, y_LSST − H_VHS, y_LSST − K_S,VHS, y_LSST − W1_CatWISE, and y_LSST − W2_CatWISE colors, respectively. The resulting log-odds scores of the leaf nodes are then combined to yield the final classification probability.
