SOLVED: 1) Load the iris sample dataset into Python using a Pandasdataframe. Perform a PCA using the Scikit Decomposition component,and provide the percentage of variance explained by each of thePrincipal Components. Compare this to the percentage of varianceexplained by each of the original features. What do youobserve?2) Use Matplotlib to plot a projection of each feature onto the1st Principal Component from the above problem against theoriginal feature itself. Which pair of features show a cl

Principal Component Analysis (PCA) is a dimensionality reduction method that reprojects data into a new coordinate system, where each axis - called a principal component - captures the maximum possible variance, preserving the most important information in the dataset. To compute PCA, we first calculate the covariance matrix of the data, which measures how features vary together. Then, we perform an eigenvalue decomposition on this matrix. Each eigenvalue indicates how much variance a particular
