Want to keep learning? … WebI have a dataset, X, with n rows and d columns. I want to take the dot product with each row to the transpose of itself. In R code this would be x %*% t(x), and this gives a d by d matrix.. I then truncate the values in the matrix using a function: Where tau is a d by d matrix.. trunc_operator = function(x, tau){ x = ifelse(abs(x) > tau, tau*sign(x), x) return(x) }
