许多利用移动设备中的传感器的应用以及应用机器学习以提供新颖的服务。然而,诸如不同的用户,设备,环境和超参数之类的各种因素影响了这种应用的性能,从而使域移位(即,来自训练源数据集的目标用户的分发偏移)是一个重要问题。虽然最近的域适应技术试图解决这个问题,但各种因素之间的复杂相互作用通常会限制其有效性。我们认为,准确估算未训练的域中的性能可能会显着降低性能不确定性。我们呈现Dapper(域适配性能估计器),其估计目标域中的适应性能,只有未标记的目标数据。我们的直觉是目标数据上模型的输出提供了模型在目标域中的实际性能的线索。 Dapper不需要昂贵的标签成本,也不需要在部署后涉及额外的培训。与四个基线相比,我们与四个真实世界传感数据集进行了评估,表明,估计精度平均17%平均占据了基线的表现。此外,我们的On-Device实验表明,与基线相比,Dapper达到了多达216倍的计算开销。

Climate change has increased the intensity, frequency, and duration of extreme weather events and natural disasters across the world. While the increased data on natural disasters improves the scope of machine learning (ML) in this field, progress is relatively slow. One bottleneck is the lack of benchmark datasets that would allow ML researchers to quantify their progress against a standard metric. The objective of this short paper is to explore the state of benchmark datasets for ML tasks related to natural disasters, categorizing them according to the disaster management cycle. We compile a list of existing benchmark datasets introduced in the past five years. We propose a web platform - NADBenchmarks - where researchers can search for benchmark datasets for natural disasters, and we develop a preliminary version of such a platform using our compiled list. This paper is intended to aid researchers in finding benchmark datasets to train their ML models on, and provide general directions for topics where they can contribute new benchmark datasets.

最近显示出一种仅通过神经元的尖峰实现的计算系统,即语法,即进行简单的英语句子的依赖性解析。我们解决了这项工作所留下的两个最重要的问题:选区(句子的关键部分,例如动词短语)和处理依赖句子的处理,尤其是中央句子。我们表明,语言的这两个方面也可以由神经元和突触以与已知或被广泛相信的语言器官的结构和功能兼容的方式来实现。令人惊讶的是,我们实施中心嵌入的方式指出了无上下文语言的新表征。
