# GN-BAE-VLN-CE

GN-BAE-VLN-CE is a companion checkpoint for [GN0](https://github.com/TeleHuman/GN0), prepared for Vision-and-Language Navigation in Continuous Environments (VLN-CE) style workflows.

GN0 is a unified research framework for **Generation**, **Evaluation**, and **Policy Learning** in Vision-and-Language Navigation. It connects 3D Gaussian Splatting-based scene construction, high-fidelity embodied simulation, and navigation policy evaluation in visually grounded indoor environments.

This repository provides a GN-BAE checkpoint variant intended to be used with GN0-related VLN-CE / GN-Bench evaluation code.

## Intended Use

This model is intended for research on embodied AI and Vision-and-Language Navigation, especially experiments that use GN0 together with VLN-CE style navigation agents or evaluation pipelines.

Use this checkpoint together with the GN0 codebase:

- Code: https://github.com/TeleHuman/GN0
- Project page: https://telehuman-gn0.github.io/
- Paper: https://arxiv.org/abs/2606.03682
- Main GN-BAE checkpoint: https://huggingface.co/TeleEmbodied/GN-BAE

## GN0 Context

GN0 consists of three connected components:

| Component | Description |
| --- | --- |
| GN-Matrix | Large-scale 3DGS navigation data with dynamic human avatars. |
| GN-Bench | Interactive benchmark and simulator for high-fidelity VLN evaluation. |
| GN-BAE | Navigation foundation model for map-based and map-free policy learning. |

GN-BAE-VLN-CE is released as part of this GN0 model ecosystem.

## Usage

Please follow the setup instructions in the GN0 repository. A typical workspace includes `VLN_CE`, `GN-Bench-Tools`, datasets, and model checkpoints:

```text
GN0
├── data
│   ├── datasets
│   │   └── GN_Matrix
│   │       └── InteriorGS_episode
│   └── scene_datasets
│       └── InteriorGS
├── GN-Bench-Tools
├── model_zoo
│   └── bae
├── VLN_CE
├── run.py
└── eval_bae_InteriorGS.sh
```

Place or reference this checkpoint according to the model path expected by your VLN-CE / GN0 evaluation script.

For the GN-Bench InteriorGS evaluation workflow, GN0 shows the following command pattern:

```bash
zsh eval_bae_InteriorGS.sh \
  --model-path model_zoo/bae \
  --chunks 1 \
  --procs-per-gpu 1 \
  --save-path tmp/bae_eval
```

Monitor evaluation progress:

```bash
watch -n 1 python analyze_results.py --path tmp/bae_eval
```

## Evaluation

GN0 reports standard VLN metrics from JSON evaluation logs:

| Metric | Meaning |
| --- | --- |
| TL | Average trajectory length |
| NE ↓ | Navigation error |
| OS ↑ | Oracle success |
| SR ↑ | Success rate |
| SPL ↑ | Success weighted by path length |

Please refer to the GN0 repository for dataset preparation, simulator setup, and full evaluation details.
