Argmin in parameter estimation

The only other difference between the functions you named are the way they structure input and output. Minimize will return the same information as ArgMin, but ... (u) ∈ argmin. ˆy∈[k] u j.

This function returns the index of the minimum element of a specified collection itr . argmin(A; dims) -> indices. This function returns the ... argmin offers abstractions over basic Vec s, ndarray and nalgebra types. For performance reasons, the latter two should be preferred. Which one to use is a ... When we use axis=0 argument in the argmin() function, it means that we want to find the indices of the minimum elements along each column of the array. In ... proxγgT (z) = argmin q. {gT (q) + 1. 2γ kq − zk2}. = argmin q. {g(Tq) + 1. 2γ kq − zk2} might be much more expensive (if g separable). • however, if T diagonal ... ˆx = arg min x.
