Suppose a new user’s data that comes in, which is stored in the vector r. Your colleague, a computer scientist, wants to apply an ‘algorithm’ on their ‘computer’ to extract extra information from r. They propose something called ‘deep heart rate parameters’ by solving for z in the problem: r = [H I] z (a) What is the dimensionality of I in this expression. (b) You tell them this idea does not convey any value and is conceptually problematic. Why? Use at most 3 sentences with linear algebraic concepts.
