Rapid identification of the leakage source enables timely mitigation, while accurate estimation of the emission strength helps assess the severity of the incident. This study presents a multi-task learning (MTL) framework for source term estimation (STE) that simultaneously predicts source location and time-varying emission strength. Three representative deep learning architectures, a Deep Feedforward Neural Network (DFNN), a Long Short-Term Memory (LSTM) network, and a Transformer, are compared under both constant and dynamic release scenarios. This work provides the first systematic evaluation of these distinct architectures within an MTL framework for STE, demonstrating the advantages of temporal feature learning for inverse modeling applications. A realistic and large-scale dataset is generated using computational fluid dynamics (CFD) and the response factor method (RFM) to simulate dispersion. Optuna-based hyperparameter optimization is employed to ensure reliable model comparison. Results demonstrate that all three models achieve strong inversion performance.
