WebIntroduction. Glioblastoma (GBM) is the most common primary malignant tumor of the central nervous system in adults, with survival rates less than 15 months after trimodality therapy. 1 However, individual heterogeneity in the survival rates is undoubtedly observed in light of several prognostic factors that have been established in the recent years. . … WebInstead of level-wise growth, Light GBM prefers leaf-wise growth of the nodes of the tree. Further, in light GBM, the primary node is split into two secondary nodes and later it chooses one secondary node to be split. This split of a secondary node depends upon which between two nodes has a higher loss.
