Appropriate Problems For Decision Tree Learning

What are appropriate problems for Decision tree learning? Although a variety of decision tree learning methods have been developed with somewhat differing capabilities and requirements, decision tree learning is generally best suited to problems with the following characteristics: 1. Instances are represented by attribute-value pairs. “Instances are described by a fixed set of attributes (e.g., …

Decision Tree Representation in Machine Learning

What are decision tree and decision tree learning? Explain the representation of the decision tree with an example. Decision Trees is one of the most widely used Classification Algorithm Features of Decision Tree Learning Method for approximating discrete-valued functions (including boolean) Learned functions are represented as decision trees (or if-then-else rules) Expressive hypotheses space, including …

List then Eliminate Algorithm Machine Learning

Consistent Hypothesis, Version Space and List then Eliminate Algorithm Consistent Hypothesis The idea: output a description of the set of all hypotheses consistent with the training examples (correctly classify training examples). Version Space: a representation of the set of hypotheses that are consistent with D an explicit list of hypotheses (List-Then-Eliminate) a compact representation of …

AO* Search (And-Or) Graph – Artificial Intelligence

AO* Search (And-Or) Graph, Advantages and Disadvantages – Artificial Intelligence – Artificial Intelligence The Depth-first search and Breadth-first search given earlier for OR trees or graphs can be easily adopted by AND-OR graph. The main difference lies in the way termination conditions are determined since all goals following an AND node must be realized; whereas …

A Star Search Algorithm – Artificial Intelligence

A Star ( A*) Search Algorithm, Advantages and Disadvantages – Artificial Intelligence – Artificial Intelligence A* is a cornerstone name of many AI systems and has been used since it was developed in 1968 by Peter Hart; Nils Nilsson and Bertram Raphael. It is the combination of Dijkstra’s algorithm and the Best first search. It …
