Linear equations are valuable for real-world modeling phenomena involving at least one variable. However, verifying if the procedure followed by a human for solving a linear equation was done correctly is still a complicated matter. In this paper, we propose a methodology for the automatic character recognition and revision of the solving procedure of linear equations with one unknown. First, a camera is used to acquire an image of the handwritten solving procedure. Then, the image is pre-processed, and each character and equation lines are segmented. Subsequently, a convolutional neural network (CNN) is used to conduct the character recognition stage. Finally, a comparison rule is applied to revise the solving procedure. The character recognition was verified on a 2800 image data set (2100 for training and 700 for testing), including the ten digits and four symbols: ×, +, -, /. The revision procedure was tested on a data set with 140 handwritten equations (125 for training and 15 for testing). The results revealed that we recognized handwritten characters with an accuracy of 99%, which is similar to the state-of-the-art. Moreover, our proposal revised the solving procedure with an efficiency of 86.66%. 相似文献

In recent years, questions of ‘character’ have become increasingly prominent in a range of policy contexts, from education to social welfare and from business to healthcare. What unites these various contemporary paens is an assumption that building ‘character’ is a crucial component of ethics and that it holds the key to establishing and maintaining virtuous conduct; moreover, that the cultivation of ‘character’ is at best under-valued and at worst actively undermined and denigrated in any number of contemporary economic and organizational practices. In this paper, we seek to interrogate key aspects of this upsurge of interest in ‘character’ as it has been articulated in particular recent and on-going debates about the reform of organizational life. We argue that this ‘turn’ suffers precisely from an abstraction and lack of contextual specificity – not simply in relation to questions of ‘character formation,’ but also in regard to matters of organization, and indeed the relationship of the one to the other – that severely curtails both its ethical reach and explanatory power. 相似文献
