Evidencepartial
On the 78-task MMEB-v2 benchmark, PLUME outperforms strong explicit-CoT UME baselines
Implicationpartial
Explicitly stated in the abstract with a specific benchmark reference.
Verificationpartial
partial
Evidencepartial
reducing reasoning from hundreds of generated tokens to fewer than 10 latent steps, delivering over 30x faster inference.
Implicationpartial
Explicitly stated in the abstract with clear numeric metrics.
Verificationpartial
partial
Evidencepartial
We propose PLUME, a latent reasoning framework that advances UME by replacing verbalized CoT with a short autoregressive rollout of continuous latent states.
Implicationpartial
Directly stated in the abstract as the core method.
Verificationpartial
partial
Evidencepartial
PLUME further introduces a semantic-anchor-guided transition adapter that steers latent rollout along different reasoning trajectories under the same fixed computation budget.
Implicationpartial
Directly stated in the abstract as a key technical component.
Verificationpartial
partial
Evidencepartial
PLUME adopts a progressive explicit-to-latent curriculum that uses verbalized reasoning only as a temporary training scaffold and gradually transfers this behavior into hidden-state computation, eliminating explicit CoT at inference.
Implicationpartial
Directly stated in the abstract as a key training method.
Verificationpartial
partial
Evidencepartial
PLUME is especially well suited to retrieval settings where relevant evidence is dense, structurally complex, and difficult to organize through verbalized intermediate rationales, such as video and visual document retrieval.
Implicationpartial
Directly stated in the abstract as a specific application strength.
Verificationpartial
partial
Evidencepartial
PLUME may have limitations if extended to tasks that inherently require explicit intermediate reasoning steps, or if the latent steps are insufficient for complex queries.
Implicationpartial
Explicitly stated in the analysis excerpt under 'caveats'.
Verificationpartial
partial
Evidencepartial
explicit CoT incurs substantial inference overhead and can compress rich multimodal evidence into a narrow textual bottleneck.
Implicationpartial
Directly stated in the abstract as a motivation for the work.
