This study developed and validated a deep learning approach to predict weekly suicide counts at the state level in the US, using real-time online, social media, and health administrative data. A long short-term memory (LSTM) neural network model was built for each of four participating states (Utah, Louisiana, New York, and Colorado). The model accurately estimated state-specific suicide rates, outperforming autoregressive models using only historical death data. This approach offers the potential for more timely estimates of suicide trends, aiding suicide prevention planning and response.
