آموزش یادگیری ماشین 18 - چطور با استفاده از ‫PCA بُعد ویژگی ها (‫featureها) رو کاهش بدیم؟

Part 18 of the Machine Learning Course from Basic to Advanced . One of the fundamental problems in the field of Machine Learning is the high dimension of the feature vector. To solve this problem, it is necessary to reduce the dimension of the data before the training process. Why? Because this both speeds up the calculations and eliminates data that is redundant and does not provide us with much information. The Principle Component Analysis (PCA) algorithm helps us do this more easily. By finding the principal components of the information, this algorithm tries to find the features that provide us with the most variance and at the same time have the least dimensionality reduction error. In this session, we will learn together why this is necessary and where it can be done? Then we will learn how this algorithm works and finally we will implement it using the sklearn library. .
