中文简介:
从结构图像中转录内容,例如从乐谱中写笔记,是一项具有挑战性的任务,因为不仅应该识别内容对象,而且还应该保留内部结构。现有的图像识别方法主要针对内容简单的图像(例如,带有字符的文本行),但无法识别内容更复杂的图像(如结构化代码),这些图像通常遵循细粒度语法。为此在本文中,我们提出了一个分层聚光灯转录网络(STN)框架,然后是一个两阶段的“从哪里到什么”解决方案。具体来说,我们首先通过一种新的聚光灯机制来决定“从哪里看”,以根据原始图像的结构聚焦于原始图像的不同区域。然后,我们决定“通过开发一个具有聚光灯区域的基于GRU的网络来相应地转录内容,来写什么”。此外,我们在STN的基础上提出了两种实现,即STNM和STNR,其中聚光灯移动分别遵循马尔可夫属性和递归建模。我们还设计了一种增强方法,通过自我改进聚光灯来完善我们的STN框架机械装置我们在许多结构图像数据集上进行了广泛的实验,结果清楚地证明了STN框架的有效性。
课程简介: I use the tagline “Data for Good” to state paronomastically how we as a community should be promoting data science, especially in training future generations of data scientists. First, we should use data science for the good of humanity and society. Data science should be used to better people’s lives. Data science should be used to improve relationships among people, organizations, and institutions. Data science, in collaboration with other disciplines, should be used to help tackle societal grand challenges such as climate change, education, energy, environment, healthcare, inequality, and social justice. Second, we should use data in a good manner. The acronym FATES suggests what “good” means. Fairness means that the models we build are used to make unbiased decisions or predictions. Accountability means to determine and assign responsibility—to someone or to something—for a judgment made by a machine. Transparency means being open and clear to the end user about how an outcome, e.g., a classification, a decision, or a prediction, is made. Ethics for data science means paying attention to both the ethical and privacy-preserving collection and use of data as well as the ethical decisions that the automated systems we build will make. Safety and security (yes, two words for one “S”) means ensuring that the systems we build are safe (do no harm) and secure (guard against malicious behavior).
