Hidden markov model with gaussian emissions
WebWe propose a method for reducing the non-stationary noise in signal time series of Sentinel data, based on a hidden Markov model. Our method is applied on interferometric coherence from Sentinel-1 and the normalized difference vegetation index (NDVI) from Sentinel-2, for detecting the mowing events based on long short-term memory (LSTM). … WebSince it 2.1 Hidden Markov Models is a stationary distribution, p∞ has to be a solution of A discrete-time Hidden Markov Model λ can be viewed as a Markov model whose states …
