Ego3DLM checkpoints
Checkpoints and annotations for Ego3DLM: Ego-Human Motion Prediction with 3D-Aware LLM (ECCV 2026).
Code: github.com/jinyubae/Ego3DLM
Files
| Path | Size | Content |
|---|---|---|
stage3_grpo/stage3_grpo.ckpt |
1.94 GB | final Ego3DLM model (Stage III, GPT-2 medium) |
stage0_pqvae/stage0_pqvae.ckpt |
73 MB | motion PQ-VAE tokenizer (2 codebooks × 2048 codes of 32-D, temporal downsampling 4) |
evaluator/text_mot_match_trainset_only_len20/finest.tar |
246 MB | text–motion matching evaluator (trained on the train split, max. 20 words), used for R-precision, d_pg / d_pp and the GRPO matching reward |
annotations/ego3dlm_annotations.tar.gz |
6 MB | data splits, sample-id mapping, narrations, semantic scene QA, spatial (obstacle / free-space) labels, normalization statistics and instruction templates |
The checkpoints hold the model weights only (no optimizer state).
The annotation bundle does not contain the motion, video and 3D scene features. They are derived from Nymeria and are produced with the preprocessing code in the GitHub repository.
