Efficient3D: A Unified Framework for Adaptive and Debiased Token Reduction in 3D MLLMs

Researchers have developed Efficient3D, a framework that accelerates 3D Multimodal Large Language Models (MLLMs) while maintaining accuracy through adaptive token pruning. The system uses a Debiased Visual Token Importance Estimator and Adaptive Token Rebalancing to reduce computational overhead without sacrificing performance, showing +2.57% CIDEr improvement on benchmarks.
