Further, there are a series of distance metrics that can be applied to calculate point-to-point distances. In this research, the K-means clustering algorithm is evaluated with three different mathematical metric

LSTM layers have three sets of parameters. The first set, kernel weights, is associated with the hidden state. These weights are:Whf,Whu,Whc, andWho. The second set is related to the input, which is named recurrent-kernel weights. This set consists ofWxf,Wxu,Wxc, andWxo. The last set...
[21] discovered a common invariance based on the assumption that different distance metrics would result in similar clustering assignments on the manifold. Based on such a common invariance, a deep clustering method is designed by minimizing the discrepancy between pairwise sample assignments for each...
By default, kmeans uses the squared Euclidean distance (see 'Distance' metrics). D— Distances from each point to every centroid numeric matrix Distances from each point to every centroid, returned as a numeric matrix. D is an n-by-k matrix, where element (j,m) is the distance from ...
In reality, there are many different scoring methods depending on what metrics matter most in a model. Usually one method is chosen as the standard but for the purpose of this analysis I have used two. The Silhouette Coefficient is calculated using the mean intra-cluster distance (a) and ...
Another thing we have to define properly is the distance function. Sometimes that’s a straightforward task, a logical one given the nature of data. For points in space, Euclidean distance is an obvious solution, but it may be tricky for features of different ‘units’, for discrete variables...
Due to the utilization of the Euclidean distance measure for clustering, the proposed KCGWO has not completely distinguished all of the clusters in the data. In order to prove the performance of the proposed KCGWO, two additional metrics, such as Mean Absolute Error (MAE) and Mean Squared ...
