An important machine learning method for dimensionality reduction is called Principal Component Analysis. It is a method that uses simple matrix operations from linear algebra and statistics to calculate a projection of the original data into the same number or fewer dimensions. In this tutorial, you will discover the Principal Component Analysis machine learning method for dimensionality.

Ori Cohen has done his PhD in computer science in the fields of machine learning, brain-computer-interface and neurobiology. References: [1] building AE in keras [2] PCA in 3 steps using Iris [3] CSC 411: Lecture 14: Principal Components Analysis & Autoencoders, page 16. [4] A Tutorial on Autoencoders for Deep Learning In the following graph, you can see that first Principal Component (PC) accounts for 70%, second PC accounts for 20% and so on. The variance explained by components decline with each component. If we retail first two PCs, then the cumulative information retained is 70% + 20% = 90% which meets our 80% criterion PCA is the most widely used tool in exploratory data analysis and in machine learning for predictive models. Moreover, PCA is an unsupervised statistical technique used to examine the interrelations among a set of variables. It is also known as a general factor analysis where regression determines a line of best fit PCA using Python (scikit-learn) My last tutorial went over Logistic Regression using Python. One of the things learned was that you can speed up the fitting of a machine learning algorithm by changing the optimization algorithm. A more common way of speeding up a machine learning algorithm is by using Principal Component Analysis (PCA) Understanding the Dimensionality Reduction in ML ML (Machine Learning) algorithms are tested with some data which can be called a feature set at the time of development & testing.
