Adaptive Residual Weighted <i>K</i>-Nearest Neighbor Fingerprint Positioning Algorithm Based on Visible Light Communication

Adaptive Residual Weighted <i>K</i>-Nearest Neighbor Fingerprint Positioning Algorithm Based on Visible Light Communication

The weighted <i>K</i>-nearest neighbor (WKNN) algorithm is a commonly used fingerprint positioning, the difficulty of which lies in how to optimize the value of <i>K</i> to obtain the minimum positioning error. In this paper, we propose an adaptive residual weighted <i>...
