System for Recognition and Evaluation of
Handwritten Arithmetic Expressions

Abstract

Recognition of mathematical expressions today is a very interesting area of application of deep learning. The problem is quite complex and requires a complex system to solve it. The problem becomes even more complex if arithmetic expressions are handwritten. The use of convolutional neural networks yields satisfactory results but leaves some room for improvement. In this paper, a simplified variant of the above problem is solved by using an approach that consists of extraction and classification of individual symbols using convolutional neural networks followed by syntactic parsing of the expression taking into account the symbol positions.
