Gaussian kernel is a popular kernel function often used in various computational biology and their applications to measure the similarity between two samples in a dataset. It can be used not only in the unsupervised situation but also in the supervised case. However, the scalar parameter belta (β) in Gaussian kernel function as shown in the following equation significantly affects the final results. This online data-driven tool is used to calculate the optimal belta (β) parameter based on the given dataset.
