Naive-Bayes Classifier in C++

This is an implementation of the Naive-Bayes Classifier in C++.

Running

Compile and run the classifier.cpp file.

$ g++ -o classifier classifier.cpp
$ ./classifier

Dataset Info

I used a custom dataset that has faces represented in txt files. Check out facedatatrain.txt file to understand the data.

datatrain directory contains the training files and dataset contains the testing ones.

NOTE: Code was written specifically for this dataset and will require significant changes before running on some other dataset.

Results

Accuracy: 89.3333%

Confusion Matrix

	Predicted Face	Predicted Non-Face
Actual Face	68	5
Actual Non-Face	11	66

Precision: 86.076%

Recall: 93.1507%

F-measure: 89.4737%
