[1, 2] Core Definition and Principles * Reconstructive Compression: Unlike a standard summary that discards internal structure to save raw space, a holographic kernel discards extraneous material to preserve the underlying structural relationships. [1, 2] * The Analogy: Where standard lossy compression acts like a summarized book jacket, a holographic kernel acts like a hologram where every small piece of the plate retains a lower-resolution view of the entire image. [1, 2] * Distinctions: The term spans multiple domains—including theoretical semantic frameworks, optical Fourier holography, and diffraction-informed deep learning where sequential kernel sizes process wave-fields while retaining spatial and frequency data. [1, 2, 3] If you're interested, we can explore: * How holographic kernels apply to semantic economy and AI memory * Their role in optical and digital holography (like CNNs or lensless microscopy) Let me know which angle you'd like to focus on.
