project applications. In this paper, we only discuss the space-time complexity and parallelism of various algorithms.Evaluation criteriaThe application of machine learning algorithms is usually taken offline after the model is trained. Put it on the line to predict. for server clusters. It is possible that training and prediction occur on the same device. But in

specific flow of the Lle algorithm is as follows (source: machine Learning Zhou Zhihua version)　　　　Lle Algorithm Summary:Key Benefits:1) can learn the local linear low-dimensional manifold of any dimension2) The algorithm comes down to the sparse matrix feature decomposition, the computational complexity is relatively small, the realization is easy.3) can deal with non-linear data, can be non-linear dimens

-domains, such as "machine learning", "Data mining", "Pattern recognition", "Natural language processing" and so on. These sub-areas may have intersections, but the focus is often different. For example, "machine learning" is more focused on algorithmic aspects. In general, "artificial intelligence" is a subject area,

classification problem, conversely, if y is a continuous real number, this is a regression problem.Given a set of sample characteristics S={x∈rd}, we do not have a corresponding y, but want to explore the set of samples in the D-dimensional distribution, such as the analysis of which samples are closer, which samples are far away, this is a clustering problem.If we want to use the subspace with lower dimensionality to represent the original high-dimensional feature space, then this is the dimen

1. Integrated Learning OverviewIntegrated learning algorithm can be said to be the most popular machine learning algorithms, participated in the Kaggle contest students should have a taste of the powerful integration algorithm. The integration algorithm itself is not a separ
