TEOChat: Large Language and Vision Assistant for Temporal Earth Observation Data

If you like our project, please give us a star ⭐ on Github for the latest updates.

😮 Highlights

TEOChat is the first language and vision assistant that can engage in conversation about sequences of temporal earth observation imagery, and exhibits impressive performance on multiple temporal instruction-following tasks.

📚 TEOChatlas: A new instruction-following dataset for temporal EO data

We introduce a new instruction-following dataset for temporal EO data called TEOChatlas which we use to train TEOChat. TEOChatlas contains 554,071 examples spanning dozens of temporal instruction-following tasks.

🤖 TEOChat: A new vision-language model for temporal EO data

We design TEOChat to use a LLaVA-style architecture, combining a temporally shared vision encoder with a LLaMA 2 LLM connected through an MLP vision-language projector

🤗 Demo

Gradio Web UI

We provide an online demo in Huggingface Spaces.

You can also run the demo locally by running the following command:

python videollava/serve/teochat_demo.py
