Gridded pixel and voxel representations form the backbone of visual computing, but they struggle to scale efficiently to large, high-dimensional data, such as volumetric medical scans and complex scientific simulations. Consequently, continuous, non gridded models such as implicit neural representations (INRs) and Gaussian splatting have gained significant research traction over the past five years. However, their use has largely been confined to signal reconstruction rather than acting as foundational data types for downstream analysis. In this talk, I will present our recent work on elevating continuous models beyond mere signal representation. First, I will discuss how injecting learned priors into INRs via strategic parameter initialization enables powerful new capabilities, including rapid, amortized fitting to novel signals and even semantic segmentation. Second, I will briefly outline our recent efforts in performing visual recognition tasks directly on 2D Gaussian image representations. Finally, I will highlight interesting future directions in this “learning through fitting” paradigm of visual computing.
