"It is a strategy of turning the higher dimensions dataset into fewer dimensions dataset while guaranteeing that it gives similar information," says one definition. These methods are commonly used in machine learning to develop a more accurate predictive model when tackling classification problems.
For instance, we may combine Dum Dums and Blow Pops to examine all lollipops at once. In both of these cases, dimensionality reduction can aid. Dimensionality reduction can be accomplished in two ways: Selection of features: From the initial feature set, we select a subset of features.
It cuts down on the amount of time and storage space needed. The reduction of multicollinearity improves the interpretation of machine learning model parameters. When data is reduced to very low dimensions, such as 2D or 3D, it becomes easier to visualise. Reduce the number of variables in your space.
Depending on the method, dimensionality reduction might be linear or non-linear. The principal linear approach, often known as Principal Component Analysis, or PCA, is explored further down.
It's one of the most widely used programmes for exploratory data analysis and predictive modelling. The variance of each characteristic is taken into account by PCA since the high attribute indicates a good separation between the classes and so minimises dimensionality.
This one is one of the best online free source to study the coding or any particular course.
Course is nice but where is the link for installation of Anaconda
Course is good understandable but I am not able to download resources (one star less only for this not able to download resources)
I am impresses by the way of teaching, what a magical teaching skill he has.
good content with free of cost
Course content and explanation method is just awesome. I like the way they presenting and specially at the end of each video content they feeding next intro content which makes motivated, excited .
The courses are very useful and encourage learning. I highly appreciate that and thank the learnvern team very much indeed for the great and nice job.

The course is explained in an excellent manner with easy interpretations and simple examples. Thank you very much Sir .Really Learnvern is doing great job offering help to many Indians.
