Machine LearningSupervised Machine LearningData AnalysisLearning AlgorithmsSupervised Machine Learning (SML) is the search for algorithms that reason from remotely provided examples to create general hypotheses, which at that point makSocial Science Electronic Publishing...
This type of data is most often used in supervised learning and it can typically be processed very quickly, even with incredibly large volumes. Unstructured data –According to industry leaders more than 80% of the data in the world is unstructured and the amount of data is growing ...
To evaluate the performance of supervised learning models, various metrics are used, including accuracy, precision, recall, F1 score, and ROC-AUC. Cross-validation techniques, such as k-fold cross-validation, can help estimate the model's generalization performance. Unsupervised Learning Evaluating uns...

K-nearest neighbors (kNN) is a supervised learning algorithm that can be used to solve both classification and regression tasks. The main idea behind this algorithm is that the value or class of a data point is determined by the data points around it. ...
For those eager to understand the basics of machine learning, here is a quick tour of the top 10 machine learning algorithms used by data scientists. 1. Linear RegressionLinear regression is perhaps one of the most well-known algorithms in statistics and machine learning. Commonly used in ...
Different algorithms analyze data in different ways. They’re often grouped by the machine learning techniques that they’re used for: supervised learning, unsupervised learning, and reinforcement learning. The most commonly used algorithms use regression and classification to predict target categories, fi...
