Group 4: Multi-Token Entropy Decoding (MED) - The researchers developed an adaptive multi-token decoder called MED, which only performs parallel decoding when the conditional entropy of the additional positions is below a set threshold, thus controlling the deviation from single-token decoding [10][24]. - Experimental results show that the MED method can achieve a 2-3 times reduction in function calls while maintaining performance [11][26]. Group 5: Post-Training Capabilities - The study highlights that MDLM's in-filling capabilities unlock new sampling and post-training mechanisms, allowing for effective post-training without the need for complex prompt designs or additional models [22][23]. - By sampling reasoning trajectories from the posterior distribution, researchers can enhance the model's performance on reasoning tasks [22][23][33].
