In this letter. we propose an indoor visible light positioning technique using a Modified Momentum Back-Propagation (MMBP) algorithm based on received signal strength (RSS) with sparse training data set. Unlike other neural network algorithms that require a large number of training data points to locate accurately. we have realized high-precision positioning for 100 test points with o... https://www.getpureroutine.com/hot-sale-ethical-nutrients-mega-magnesium-powder-citrus-450g-for-sale-save-big/
