Bellman's "curse of dimensionality" applies to many widely-used data analysis methods in high-dimensional spaces. One way to address this problem is by array permuting methods, involving now/column reordering. Such methods are closely related to dimensionality reduction methods such as principal ...
It requires only the maintenance of a low-dimensional embedding. Then, the clustering solution is found by applying the bisection method to the similarity matrix. In addition to the above, we propose an improvement to LSH that is beneficial for its use on high-dimensional data. This improvement...

It performs very well on high dimensional data, discovering clusters that cannot be found by known algorithms. It also identifies outliers in the data as a by-product of the cluster formation process. A validity measure that depends on the main clustering criterion is also proposed to tune the...

learning, where the goal is to find meaningful and or useful groups in the data18. A survey of clustering algorithms can be found in Xu and colleagues19and of clustering in high-dimensional data in Kriegelet al.20. It is this analysis that we combine with the more traditional supervised ...
Support Vector Machines(SVM): Maps data to a high-dimensional feature space to find optimal hyperplanes for classification. k-Nearest Neighbors (k-NN): Assigns a class to an instance based on the classes of its k nearest neighbors. 2. Regression ...
While this approach works well with low- to medium-dimensional datasets, it is difficult to apply to large high-dimensional datasets, especially if the clusters are not clearly separated and the dataset also contains noise (data that does not belong to any cluster). In this case, more sophisti...
High Clustering In subject area: Computer Science High clustering refers to the process of grouping high-dimensional datasets with noise using density-based spatial clustering techniques, which requires further investigation in the field of computer science.
