Extremely large computation time in a small non convex problem
回答済みI am trying to solve a principal components problem in Gurobi. This problem is defined as: $$ max_w(w^tX^tXw) \quad s.t. \quad \|w\|_2=1 $$ I have programmed the following function that solves this...

How to add L1 norm as a constraint in PCA
回答済みI am trying to solve the PCA problem adding an extra \(L_1\) constraint into it. Given a data matrix \(X\), my objective function to solve is \[max_w{w^tX^tXw} \quad s.t. \quad \|w\|_2=1, \quad \|...

Principal component analysis in Gurobi as a non convex problem. Inaccurate solution
回答済みI am programming PCA in Gurobi python as a non convex optimization problem. I know that PCA has an analytical solution much easier to calculate but I am interested in programming this as a first st...

Solving linnear regression in Gurobi python
回答済みI am new to gurobi and decided to solve a well known problem as regression. I found this notebook https://gurobi.github.io/modeling-examples/linear_regression/l0_regression.html where an L0 penaliz...
