Machine Learning is a type of Artificial Intelligence that teaches machines to learn from past experiences or provided data. Different algorithms like KNN, decision trees, and support vector machines are used in machine learning to make predictions or cluster data. The main types are Supervised, which makes predictions, and Unsupervised, which groups data. Deep Learning, a part of machine learning, is about studying neural networks to make the machine smarter. The goal of the article was to explore how machine learning algorithms are used across various fields. The researchers introduced different machine learning algorithms and discussed their applications in areas like decision making and data analysis, showing how these methods can help us solve problems and make better decisions based on data patterns.
