SimPOTrans adopts a two-stage RL post-training pipeline: the first stage lets the model produce behavior conducive to simultaneous interpretation under partial speech input, and the second stage further strengthens its adaptive capability.

UnverifiedMainstream code large models all adopt a two-stage strategy of "pretraining + instruction fine-tuning," with the second stage using alignment techniques such as RLHF or DPO.77% similarUnverifiedSimPOTrans is a reinforcement-learning-based framework that adapts a model originally built for offline speech translation into a conversational simultaneous interpretation model.73% similarUnverifiedThe reason SimPOTrans can control the trade-off solely by adjusting chunk size is that RL post-training has already taught the model to make reasonable decisions when information is incomplete.73% similarVerifiedEach RL training step requires running inference (generating rollouts) and backpropagation (updating weights) simultaneously, making the compute requirements far higher than ordinary fine-tuning.70% similarUnverifiedIn ChatGPT's training, the pre-training phase uses unsupervised learning for next-token prediction, the instruction fine-tuning phase introduces supervised learning, and finally RLHF is used to align the model's outputs.66% similar
