Abstract
Handwritten Character Recognition in Indian scripts is a complex problem compared to printed characters. This paper concerns the handwritten isolated Devanagari characters, mainly consonants of 36 classes. The dataset for Devanagari Characters available at UCI library is chosen for this work which consists of 72,000 images for classification. CNN, Alexnet, LeNet and modified LeNet, are used for classification of this dataset. While CNN achieved an accuracy of 98.63% for the training data and 97.71% for unseen data, Alexnet has shown an accuracy of 98.71% accuracy for unseen data and 96.78% for training data. Experiments on LeNet and Modified LeNet have compromised the results with 87.76% maximum. Deep Learning algorithms were analysed with different training and testing data split (80:20, 70:30 and 90:10) with varying combinations of epochs (40, 50, 150).
