MathWriting
收藏资源简介:
MathWriting数据集是迄今为止最大的在线手写数学表达式数据集,由谷歌研究院创建。该数据集包含23万个人工编写的样本和额外的40万个合成样本,不仅适用于在线HME识别,还可通过光栅化用于离线ME识别。数据集涵盖了244个数学符号和10个语法标记,支持多种结构,如矩阵。创建过程中,数据主要通过内部Android应用收集,使用数字笔或触摸屏在设备屏幕上复制数学表达式。MathWriting数据集的应用领域广泛,旨在解决手写数学表达式识别的问题,推动相关技术的发展。
The MathWriting dataset, created by Google Research, is the largest online handwritten mathematical expression (HME) dataset to date. It contains 230,000 manually authored samples plus an additional 400,000 synthetic samples, and is applicable not only to online HME recognition but also to offline ME recognition through rasterization. The dataset covers 244 mathematical symbols and 10 grammatical markers, and supports diverse structures including matrices. During its development, the data was primarily collected via an internal Android application, where users copied mathematical expressions on device screens using digital pens or touchscreens. The MathWriting dataset has a wide range of application scenarios, aiming to solve the problem of handwritten mathematical expression recognition and advance the development of relevant technologies.
