Intermittent daily rainfall requires temporal pattern extraction and correction of newly observed prediction errors. This paper presents an event-triggered convolutional neural network--long short-term memory model with prediction-error closed-loop feedback (ECF-CNN-LSTM) for seasonal one-day-ahead rainfall forecasting. A 30-day window supplies 31 causal rainfall-history and calendar features. A binary gate controls a zero-initialized, bounded residual and learns from the expected prediction errors of its inactive and active alternatives. A separate chronological controller uses each newly observed error to adjust subsequent forecasts. The single-series Tengzhou, Shandong dataset contains 97... More >
