A Comparison Between Long Short-Term Memory and Hidden Markov Model to Predict Maize Production in Nigeria
Due to population increase and import constraints, maize, a key cereal crop in Africa, is experiencing a boom in demand. Given this, the study's focus is on determining how maize output in Nigeria interacts with various climatic factors, particularly rainfall and temperature. The Hidden Markov Model (HMM) and the Long Short-Term Memory neural network (LSTM) are compared in this context to assess their performance. A variety of performance indicators, such as correlation, Mean Absolute Percentage Error (MAPE), Standard Error of the Mean (SEM), and Mean Square Error (MSE), are used to evaluate the models. The outcomes show that the HMM performs better than the LSTM, with an RMSE of 1.21 and a MAPE of 12.98 demonstrating greater performance. Based on this result, the HMM is then used to forecast maize yield while taking the effects of temperature and rainfall into account. The estimates highlight the possibility for increasing local output by demonstrating a favourable environment for maize planting in Nigeria. In order to help the Nigerian government in its efforts to increase maize production domestically, these studies offer useful insights.
