• B+ Tree

A B+ Tree is a self-balancing, multi-level indexing data structurecommonlyusedindatabasemanagementsystems and file systems. It is an extension of the B-Tree and is optimized for systems that read and write large blocks of data.InaB+Tree,allactualdatarecordsarestoredinthe leafnodes,whileinternalnodesonlystorekeysthatactas guidesforsearching.

Theleafnodesarelinkedsequentially,whichmakesrange queries and ordered traversal highly efficient. B+ Trees maintainbalancebyensuringthatallleafnodesremainat the same depth, thereby providing logarithmic time complexity for search, insertion, and deletion operations. Due to these properties, B+ Trees are widely used for indexinginrelationaldatabases.

A separate Decision Tree is trained on each subset.

Additionally, Random Forest introduces randomness by selecting a random subset of features for splitting at each node. The final prediction is obtained by aggregating the outputsofallindividualtrees,eitherthroughmajorityvoting (for classification) or averaging (for regression).
