3 Must-Ask Questions Before Choosing That Machine Learning Algorithm!

You know that you want to build a predictive model. You've framed your problem in terms of classification or regression. You've prepared some training data (which took an age). Now there's just the small matter of choosing an appropriate algorithm.

You've heard or experienced first hand that Random Forests, Elastic Net Regression or Deep Belief Networks are "the business" and so you're going to use one of these (you've probably already verified that these algorithms are appropriate to…

Iterative Algorithm for Linear Regression

I am trying to solve the regression Y=AX where Y is the response, X the input, and A the regression coefficients. I came up with the following iterative algorithm:

Ak+1 = cYU + Ak (I-cXU),


where:



  • c is an arbitrary constant
  • U is an arbitrary matrix such that YU has same dimension as A. For instance U = transposed(X)…
