 # AlphaNum Dataset
 
 ## Dataset Summary
-The AlphaNum dataset, created by Louis Rädisch, is a collection of handwritten characters and digits intended for the use in Optical Character Recognition (OCR) tasks. This dataset is a compilation from various sources and includes labels from 0-35, where 0-25 represent the letters A-Z and 26-35 represent the digits 0-9. The images from the MNIST dataset included have been color inverted.
+The AlphaNum dataset, created by Louis Rädisch, is a collection of handwritten grayscale characters and digits of the size 28x28 intended for the use in Optical Character Recognition (OCR) tasks. This dataset is a compilation from various sources and includes labels from 0-35, where 0-25 represent the letters A-Z and 26-35 represent the digits 0-9. The images from the MNIST dataset included have been color inverted.
+To bring together the different datasets, vision transformer Models have been fine tuned to further increase the accuracy of the data. For instance the  "A-Z handwritten alphabets" had no seperation between big and small letters.
