WebMay 28, 2024 · Q6. Explain the difference between the CART and ID3 Algorithms. The CART algorithm produces only binary Trees: non-leaf nodes always have two children (i.e., questions only have yes/no answers). On the contrary, other Tree algorithms, such as ID3, can produce Decision Trees with nodes having more than two children. Q7.
WebThe basic algorithm used in decision trees is known as the ID3 (by Quinlan) algorithm. The ID3 algorithm builds decision trees using a top-down, greedy approach. Briefly, the … WebDecision trees perform greedy search of best splits at each node. This is particularly true for CART based implementation which tests all possible splits. For a continuous variable, …
Greedy algorithms can be characterized as being 'short sighted', and also as 'non-recoverable'. They are ideal only for problems that have an 'optimal substructure'. Despite this, for many simple problems, the best-suited algorithms are greedy. It is important, however, to note that the greedy algorithm can be … See more A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a … See more Greedy algorithms have a long history of study in combinatorial optimization and theoretical computer science.
