ClassifierToolbox : A Matlab toolbox for classifier.


Authors: Hiroyuki Kasai

Last page update: Seo. 11, 2017

Latest library version: 1.0.7 (see Release notes for more info)

Introduction

This package provides various tools for classification, e.g., image classification, face recogntion, and related applicaitons.

First to do: configure path

Run run_me_first for path configurations.

%% First run the setup script
run_me_first; 

Second to do: download datasets and external libraries

Run download for downloading datasets and external libraries.

%% Run the downloading script
download; 
  • If your computer is behind a proxy server, please configure your Matlab setting. See this.

Usage example: ORL face dateset demo: 3 steps!

Now, just execute demo for demonstration of this package.

%% Execute the demonstration script
demo; 

The "demo.m" file contains below.

%% load data
load('./dataset/AR_Face_img_60x43.mat');

%% set option
options.verbose = true;

%% LSR
[accuracy_lsr, ~, ~] = lsr(TrainSet, TestSet, train_num, test_num, class_num, 0.001, options);

%% LRC
accuracy_lrc = lrc(TrainSet, TestSet, test_num, class_num, options);

%% show recognition accuracy
fprintf('# LSR: Accuracy = %5.5f\n', accuracy_lsr);
fprintf('# LRC: Accuracy = %5.5f\n', accuracy_lrc);

Let take a closer look at the code above bit by bit. The procedure has only 3 steps!

Step 1: Load data

First, we load datasets including train set and test set.

load('./dataset/AR_Face_img_60x43.mat');

Step 2: Perform solver

Now, you can perform optimization solvers, i.e., LSR and LRC with appropriate paramters.

%% LSR
[accuracy_lsr, ~, ~] = lsr(TrainSet, TestSet, train_num, test_num, class_num, 0.001, options);

%% LRC
accuracy_lrc = lrc(TrainSet, TestSet, test_num, class_num, options);

Step 3: Show recognition accuracy

Finally, the final recognition accuracis are shown.

fprintf('# LSR: Accuracy = %5.5f\n', accuracy_lsr);
fprintf('# LRC: Accuracy = %5.5f\n', accuracy_lrc);

That's it!
