Goal:PCA aims to find a new set of orthogonal variables that capture the maximum amount of variance in the data, while SVD aims to find a decomposition of a matrix into singular values and associated singular vectors. Use of the Data:PCA is an unsupervised learning technique that can be us...
The use of principal component analysis (PCA) was also evaluated together with the k-means model. Several supervised and unsupervised learning metrics were evaluated. The SOM model with the Gaussian neighborhood function provided the best results, with an F1-score of 0.91 and a more defined ...
Let’s understand the main methods of using machine learning in SEO and how they are used today. 1. Support Vector Machines Classification is a process that significantly facilitates segmentation. In other words, support-vector machines (SVM) are a set of prediction algorithms that classify custo...
PCA Use Cases Example 1: Improve Algorithm Runtime KNN is a popular machine learning classifier, however its performance can be slow. In the next example, we produced a classification dataset of 1M records with 200 features. Only 5 of them informative. ...

Digital learning environments create a dynamic and engaging learning and teaching context that promotes a deeper understanding of complex concepts, eases the teaching process and fosters a passion for learning. Moreover, integrating interactive materials into pilot courses can assist teachers in better ass...

We first examined the impact of SMOTE on the data structure, beginning with the cannabis variable as illustrated in Fig.1, and extended this analysis to other dependent variables. Principal Component Analysis (PCA) was applied to both the original and SMOTE-enhanced datasets, with a comparison of...
