Researchers have developed models to predict El Niño events using delayed observations of the Niño-3.4 index. By analyzing data up to July 2026, they found that incorporating delayed information significantly improves forecasts compared to simpler methods. While increasing model complexity like multilayer perceptrons or recurrent neural networks (GRU, LSTM) did not yield further gains, a simple SINDy recurrence and shallow recurrent architectures proved effective. The study suggests that the representation of past information is more crucial than model complexity for predicting El Niño's evolution. AI
