Greedy algorithm in ml
WebThe decision tree learning algorithm. The 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. … WebNov 19, 2024 · Let's look at the various approaches for solving this problem. Earliest Start Time First i.e. select the interval that has the earliest start time. Take a look at the following example that breaks this solution. This solution failed because there could be an interval that starts very early but that is very long.
