Schematic Diagram of the SimpleRNN cell. The basic ungated RNN formulation shown here is used to introduce the notation for recurrent state updates over time. In this work, SimpleRNN additionally serves as a baseline temporal model in the ablation study (Sect. 4.3), while the final MSP-SRC framework adopts a GRU unit as the recurrent module (Sect. 3.3.2).
