Two methods of machine learning--supervised learning and unsupervised learning (popular understanding) _ Machine Learning

Objective Machine learning is divided into: supervised learning, unsupervised learning, semi-supervised learning (can also be used Hinton said reinforcement learning) and so on. Here, t

Machine Learning--unsupervised Learning (non-supervised learning of machines learning)

Earlier, we mentioned supervised learning, which corresponds to non-supervised learning in machine learning. The problem with unsupervised learning is that in untagged data, you try to find a hidden structure. Because the examples

Definition of machine learning and supervised learning and unsupervised learning

. It is used to organize clusters of large computers. The second application is the analysis of social networks. There is also market segmentation. Many companies have large databases that store consumer information. So, you can retrieve these customer data sets, automatically discover the market classification, and automatically divide the customer into different market segments so that you can automatically and effectively sell or sell together in different segments of the market. Finally,

Python machine learning and practice Coding unsupervised learning classical model data clustering and feature reduction

used to evaluate the data itself with the correct category information using the ARI Ari indicator is similar to the method of calculating accuracy in the classification problem, while also taking into account the problem that the cluster cannot match the classification mark one by one② if the data being used for evaluation does not have a category, then we are accustomed to using contour coefficients to measure the quality of the clustering results. The contour factor also takes into account t
