About me

I am interested in creating data-efficient AI models for various computer vision/robotics perception tasks by pre-wiring deep learning with generic innate knowledge priors. This eliminates the need to collect and annotate large datasets, as built-in knowledge no longer has to be learned. My work exhibits leading performance while reducing data demand substantially, particularly in processing images and point clouds.
