Deep dives

Generative Interactive Environment Learning

The core concept of this research focuses on creating a generative interactive environment that learns solely from video data, allowing users to interact with generated scenes as if they were real. By utilizing a vector quantization (VQ) model to discretize video frames, the approach enables the model to predict tokens that capture the essence of various environments and their dynamics. This learning process emphasizes the development of a consistent action space, aiding in predicting subsequent frames by ensuring that the model can adapt its responses based on the distance and speed of moving objects. The design allows users to engage with the model actively, offering a unique opportunity to influence the outcome of generated sequences and experience a blend of creativity and interactivity.
