1. 人脸检测问题 在实际工程应用中，常常会面临非常复杂的工况。一方面算法准确度会受到很多因素影响，例如目标遮挡、光线变化、小尺寸人脸等等。另一方

Concentrate your bets: focus on select use cases and tackle barriers to adoption such as security, ROI, IT and operational technology integration. Package IoT solutions into scalable products that you then can roll out to customers. Don’t try alone: partnerships tend to be more effective with selective approach based on the use case; level: author: Kartikeya Bhardwaj, CA,USA; WeiChen(Carnegie Mellon University); Radu Marculescu(Texas at Austing) date: 2020 keyword: Federated Learning;

1. IQ Signals 1. Basic signal $$ basic \quad wave: v(t)=A*sin(2\pi ft+\phi)\ $$ 2. Simple Amplitude Modulation $$ simple\quad amplitude \quad modulation: v(t)=A(t)*sin(2\pi ft +\phi)\ $$ 3. Quadrature signals(正交信号) the amplitude of the “in-phase” signal =I: $I*cos(2\pi ft)$; the amplitude of the “90 degree” signal=Q: $Q*sin(2\pi ft)$ 4. Digital Modulation–Binary Phase Shift Keying $I(t)$ varies between [+1, -1];

人类的皮肤可以感知法向力和剪切力的细微变化(即自解耦)，并能够以更高的分辨率感知刺激（即超分辨）。换句话说，人类的指尖可以感受到压力和纹理，
