Learn about dimensionality reduction in machine learning, including its key techniques, real-world applications, benefits, and challenges.
Dimensionality reduction is a useful way to prevent overfitting and to solveclassification and regressionproblems. This process is also useful for preserving the most relevant information while reducing the number of features in a data set. Dimensionality reduction removes irrelevant features from the data...
Thus, dimensionality reduction is an ubiquituous problem and together with multivariate data visualization a topic of interdisciplinary research interest for more than three decades. Recently, high economic interest applications, e.g., data mining and knowledge discovery applications, give renewed strong ...
In this article, we looked at the simplified version of Dimensionality Reduction covering its importance, benefits, the commonly methods and the discretion as to when to choose a particular technique. In future post, I would write about the PCA and Factor analysis in more detail....

Electric load forecasting is crucial in the planning and operating electric power companies. It has evolved from statistical methods to artificial intelligence-based techniques that use machine learning models. In this study, we investigate short-term lo
dimensionality reduction techniques are essential. These methods help reduce the number of features without losing much information, improving or maintaining model performance. This guide explores the concept of dimensionality reduction, its importance, and 12 practical techniques, each with Python implementat...

1. Size and Dimensionality Consider the Size: The ideal dataset for clustering and dimensionality reduction should be sufficiently large to demonstrate the benefits of dimensionality reduction. Small datasets may not showcase the advantages of reducing feature dimensions effectively. High-Dimensional Data:...
(SNP) arrays to identifying associations between loci and traits. Even though GWAS are proved to be useful3, there are some drawbacks as well. GWAS identifies loci so that each locus is statically significant (on its own). However, complex diseases are extremely polygenic and it therefore ...
