Prakhar Kaushik

My research bridges cognitive AI and NeuroAI with 3D vision, computer graphics, continual learning, interpretability, and reasoning. I study structured, compositional understanding of the world and the models we build, aiming to make artificial visual and perceptual intelligence more human-like. I am a PhD candidate in Computer Science at Johns Hopkins University, advised by Alan Yuille.

My work advances 3D part-based representation learning, bringing machine perception closer to how humans understand objects through their parts and relationships. This perspective connects my work on efficient 3D representations, unsupervised domain adaptation for 3D pose, joint part segmentation and naming, and scene understanding. My graphics work extends to editable animal fur reconstruction.

In continual learning, my contributions include formalizing catastrophic remembering and developing Share for almost strict continual learning. My work on adapter recycling explores how learned structure can be reused for efficient adaptation and inference.

In interpretable AI and the physics of AI, my work exposes stark failures of feedforward 3D reconstruction models, including hallucinated geometry from unrelated images or random noise. The Universal Weight Subspace Hypothesis provides evidence of shared low-dimensional weight structure across independently trained networks, with implications for efficient learning, inference, and continual adaptation.

Much of this work is first-authored or co-first-authored. Independent thinking, novelty, creativity, and ethical research guide my work.

I welcome researchers interested in connecting cognitive principles and the physics of learning with practical advances in 3D vision, graphics, and continual learning. Get in touch.
