The MNIST database of handwritten digits, has a training set of 60,000 examples, and a test set of 10,000 examples. It is a subset of a larger set available from NIST. The digits have been size-normalized and centered in a fixed-size image (28x28)
It is a good database for people who want to try learning techniques and pattern recognition methods on real-world data while spending minimal efforts on preprocessing and formatting.
About the Loader
This is a short C++ programm to parse the MNIST Dataset.
(which is one of the most popular datasets to train neural networks)
- All four MNIST data files are needed (training images + labels / test images + labels)
- Path to those files is passed in the constructor
- The class has two members (trainingData & testData) that hold the 60.000 & 10.000 digits
- The pixel data of each digit is stored in a two dimensional vector (rows / columns)
- Printout function, to verify that the digits + labels are parsed correctly
