If you are using sigmoid activation functions, rescale your data to values between 0-and-1. If you’re using the Hyperbolic Tangent (tanh), rescale to values between -1 and 1. This applies to inputs (x) and outputs (y). For example, if you have a sigmoid on the output layer to p...
In order to understand the structure of a given undirected weighted graph \(G = (V, E, d)\) a crucial step is to define a representation map \(R : V \rightarrow {{\,\mathrm{\mathbb {R}}\,}}^k\) for some \(k \in \mathbb {N}\), so that the Euclidean distance between R...

[76] used K-means clustering to understand the similarity and relationship among Hedychium species, successfully classifying samples into four major clusters. Supervised learning methods: (1) Support Vector Machine (SVM): SVM can be used for both classification and regression tasks, by changing the...
When setting up a predictive model, the first step should always be to understand the data. Although scanning raw data and calculating basic statistics can lead to some insights, nothing beats a chart. However, fitting multiple dimensions of data into a simple chart is always a challenge (dimen...
