Machine Learning and Central Banking
当然，机器学习 (ML) 现在无处不在。几十年来，时间序列分析视角一直与 ML 相匹配（简约预测模型允许错误指定；样本外评估；集合平均等），因此即使存在许多差异，也存在许多重叠领域。有趣的是，ML 在中央银行环境中变得特别有用。例如，费城联邦储备银行现在明确招募和聘用“机器学习经济学家”。目前他们有三个，他们正在寻找第四个！在这方面，特别有趣的是，《计量经济学杂志》正在征集关于“经济政策机器学习”的特别专题论文，客座编辑来自各种领先的中央银行和大学。请参阅 https://www.bankofengland.co.uk/events/2022/october/call-for-papers-m

Wi Vi: Using wifi signals to sense human presence and activity
摘要：Wi-Fi 信号通常是发射器和接收器之间的信息载体。在本文中，我们展示了 Wi-Fi 还可以扩展我们的感官，使我们能够透过墙壁和关门看到移动的物体。特别是，我们可以利用这种信号来识别封闭房间内的人数及其相对位置。我们还可以识别墙后的简单手势，并结合一系列手势将信息传达给无线接收器，而无需携带任何传输设备。本文介绍了两个主要创新。首先，它展示了如何使用 MIMO 干扰消除来消除静态物体的反射并将接收器聚焦在移动目标上。其次，它展示了如何通过将人体的运动视为天线阵列并跟踪由此产生的射频波束来跟踪人体。我们通过构建来证明我们设计的有效性。论文链接：http://people.csail.mit
