WebBestFirst: Searches the space of attribute subsets by greedy hillclimbing augmented with a backtracking facility. Setting the number of consecutive non-improving nodes allowed controls the level of backtracking done. Best first may start with the empty set of attributes and search forward, or start with the full set of attributes and search backward, or start … WebWe show that ID3/C4.5 generalizes poorly on these tasks if allowed to use all available attributes. We examine five greedy hillclimbing procedures that search for attribute …
WebThe selection of attribute g stands for the greedy component of our approach, whilst the initial at-tributes in step 1 and the attribute f account for our ‘humanlikeness as frequency’ assumption. The overall effect attempted is the following: - Highly frequent attributes are always selected.
