The core of WiMi's Trimmed K-Means algorithm is the symmetry and asymmetry of the blockchain. Symmetry, which means that a complete record of transactions is kept at each node, ensures ...

In the proposed algorithm, they extend the K-Means clustering process to calculate a weight for each dimension in each cluster and use the weight values to identify the subsets of important ...

The k-means algorithm is often used in clustering applications but its usage requires a complete data matrix. Missing data, however, are common in many applications. Mainstream approaches to ...
