正如摩根士丹利电信设备分析师斯科特科尔曼所言，4G是一种“全IP、端到端的、设备未知的应用平台，第三方开发商可采用它写入应用开放式系统”。对于4G的定位，他还指出：“对于我们在移动互联的世界中主要使用的各项服务——如浏览网页或收发邮件，现有的3G网络已基本足够，但4G将会把应用和服务体验推上更高的水平。”

Commercial buildings use 73% of all electricity consumed in the United States [30], and numerous studies suggest that there is a signi cant unrealized opportunity for savings [69, 72, 81]. One of the many reasons this problem persists in the face of nancial incentives is that owners and operators have very poor visibility into the operation of their buildings. Making changes to operations often requires expensive consultants, and the technological capacity for change is unnecessarily limited. Our thesis is that some of these issues are not simply failures of incentives and organization but failures of technology and imagination: with a better software framework, many aspects of building operation would be improved by innovative software applications.

In the knowledge-tracing model, error metrics are used to guide parameter estimation towards values that accurately represent students' dynamic cognitive state. We compare several metrics, including log likelihood (LL), root mean squared error (RMSE), and area under the receiver operating characteristic curve (AUC), to evaluate which metric is most suited for this purpose. LL is commonly used as an error metric in Expectation Maximization (EM) to perform parameter estimation. RMSE and AUC have been suggested but have not been explored in depth. In order to examine the e ectiveness of using each metric, we measure the cor- relations between the values calculated by each and the distances from the corresponding points to the ground truth. Additionally, we examine how each metric compares to the others. Our ndings show that RMSE is signi cantly better than LL and AUC. With more knowledge of e ective error metrics for estimating parameters in the knowledge-tracing model, we hope that better parameter searching algorithms can be created.
