How to visualize multidimensional data

#1

how we come to know that on this dataset linear regression should be applied or any other algorithm for better accuracy.
Like in 1-dimensional dataset we can plot and see straight line and similarly in 2-dimensional dataset linear plan can be passed so my question is how can we visualize in multidimensional data??
and how we come to know that we should apply linear regression on this dataset?

hey @anuj_singla8 ,
To visualize multi dimensional data , there are various techniques. Like TSNE , UMAP , etc.
But , understand one thing , while choosing an algorithm you first need to understand the algorithm.
Linear regression doesn’t works every time, there are multiple things to be checked first.

This thing you will only learn by practice on more and more datasets, understand the things , data and all.
