How To Install lua-torch-optim on Ubuntu 18.04

In this tutorial we learn how to install lua-torch-optim on Ubuntu 18.04. lua-torch-optim is Numeric Optimization Package for Torch Framework

Introduction

In this tutorial we learn how to install lua-torch-optim on Ubuntu 18.04.

What is lua-torch-optim

lua-torch-optim is:

This package contains several optimization routines and a logger for Torch.

The following algorithms are provided:

  • Stochastic Gradient Descent
  • Averaged Stochastic Gradient Descent
  • L-BFGS
  • Congugate Gradients
  • AdaDelta
  • AdaGrad
  • Adam
  • AdaMax
  • FISTA with backtracking line search
  • Nesterov’s Accelerated Gradient method
  • RMSprop
  • Rprop
  • CMAES All these algorithms are designed to support batch optimization as well as stochastic optimization. It’s up to the user to construct an objective function that represents the batch, mini-batch, or single sample on which to evaluate the objective.

This package provides also logging and live plotting capabilities via the optim.Logger() function. Live logging is essential to monitor the network accuracy and cost function during training and testing, for spotting under- and over-fitting, for early stopping or just for monitoring the health of the current optimisation task.

There are three methods to install lua-torch-optim on Ubuntu 18.04. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
