what number is a dimension is pca linear how many dimensions does it take to convert a vector to a vector which number must be linear how to reduce an 8 dimension vector to 3 dimensions how can you reduce a number of variables to three how many variables in an pca vector how are the dimensions of variables reduced how many variables must be to reduce a vector how many variables can be reduced to one how many dimensions can be reduced to what does pca stand for in math can dimensions and dimensions be reduced how is eight dimensions reduced how to reduce dimensions what does it mean when two variables are linear in pca how many dimensions can a linear vector of 3 be reduced to? what is the math for pca? how many dimensions are in a vector how can 8 dimensions be reduced to 3?
