Dimensionality reduction in Machine Learning

The complexity of any classification or regression algorithm depends on the number of inputs to the model. This determines the time and space complexity and the necessary number of training examples to train such a classification or regression algorithm. In this article, we discuss what is dimensionality reduction, how dimensionality reduction is implemented, and the …

Approaches to Artificial Intelligence

Approaches to Artificial Intelligence Turing Test and Rational Agent Approaches According to latest research, definitions of artificial intelligence vary along main dimensions thought processes and reasoning, and behavior. Thus views of Al fall into four categories Thinking Humanly (The Cognitive approach) Acting Humanly (The Turing Test approach) Thinking Rationally (The Laws of Thought approach) Acting …

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., …
