Abstract: This letter investigates channel estimation for ultra-massive multiple-input multiple-output (MIMO) communications. We propose a joint low-rank and sparse Bayesian estimation (LRSBE) ...

Abstract: Streaming graph signal (GS) estimation is common in various network systems. Several graph filter algorithms have been proposed for streaming GS estimation, but they still fail to reach ...

Performs recursive feature elimination to find optimal feature subset. Tracks performance at each step and identifies best configuration.

头部姿态估计是计算机视觉中的一个具有挑战性的问题，因为它需要完成多个步骤。 首先，我们需要在画面中定位人脸，然后识别出各种面部特征点。 如今，当人脸正对摄像头时，识别人脸似乎是一个简单的任务。但问题在于，当人脸处于某个角度时，由于 ...
