Google has also released pretrained general-purpose BERT models that have been trained on a large corpus of unlabelled text including Wikipedia.
分类:样本属于两个或更多类,我们想从已经标记的数据中学习如何预测未标记数据的类别。
Classification: Samples belong to two or more classes and we want to learn from already labeled data how to predict the class of unlabeled data.
年,伊利诺伊大学的研究人员在大学校园内留下了297个未标记的USB闪存盘,看看会发生什么。
Introduction In 2016, researchers from the University of Illinois left 297 unlabelled USB flash drives around the university campus to see what would happen.
因此与标签处理相关的成本可能使得完全标注的训练集不可行,而获取未标记的数据相对便宜。
The cost associated with the labeling process thus may render large, fully labeled training sets infeasible, whereas acquisition of unlabeled data is relatively inexpensive.
在此框架下,需要一个机器学习系统来发现未标记数据中的隐藏结构。
In this framework, a machine learning system is required to discover hidden structure within unlabelled data.
For example, social media applications, such as Twitter, Instagram and SnapChat, all have large amounts of unlabeled data.
使用来自三种不同真实世界任务的文本获得的实验结果表明,使用未标记的数据可将分类错误减少多达30%。
Experimental results, obtained using text from three different real-world tasks, show that the use of unlabeled data reduces classification error by up to 30%.

将未标记为dynamic的类视为密封的,这意味着无法向该类的实例添加属性。
Classes that are not marked as dynamic are considered sealed, which means that properties cannot be added to instances of the class.
然后刻录机将读取这些标记,检查标记区域的反射强度与未标记区域的反射强度的对比情况。
The burner will then read over these marks, checking for the intensity of reflection in marked areas as compared to unmarked areas.
通过目前的设置,使用100个标签样本和47000个未标记的样本,分类误差约为3%。
With the current setting, the classification loss is about 3% using 100 labeled samples and 47,000 unlabeled ones.
在一些国家办事处,没有详细的资产存货清单,资产并未标记独特的资产识别号码。
In some country offices there was no detailed inventory listing of assets, and assets had not been tagged with unique asset identification numbers.
现有哪些国家措施可以防止制造、储存、转让和持有未标记或未适当标记的:.
What national measures exist to prevent the manufacture, stockpiling, transfer and possession of unmarked or inadequately marked.
Train a classifier with semi-supervised learning(where the classifier learns from both labeled and unlabeled data… and with GANs, also learns from completely imaginary data).
ImageNet has taken years and thousands of hours to create, while we typically only need unlabelled data of each domain for creating domain-invariant representations.
