  • Why VGGT Stays Stable Under Sparsty Unlike Later Models

    An optimization-first analysis of why VGGT's simpler architecture produces more geometrically consistent 3D reconstructions from few images than its higher-capacity successors — examining training dynamics, basin formation, gradient alignment, and the cost of abandoning a shared backbone.
  • Neural Implicit Scene Reconstruction from WiFi CSI Observations

    A comprehensive feasibility study on using WiFi Channel State Information for dense 3D geometry reconstruction via neural implicit representations — covering the RF perception lineage, neural rendering, non-visual NeRF analogues, dataset gaps, proposed architecture, and a research roadmap.

  • What a Scary World This Is Without My Veil

    This isn’t a crisis of belief—it’s the mourning of it.
  • Notes from Probabilistic Robotics

    Probabilistic Robotics by Sebastian Thrun aimed to teach me how to model uncertainty in robot perception and control using probabilistic techniques.
  • Notes from Intro to RL

    This is a summary from my understanding of reinforcement learning, based on the book Reinforcement Learning: An Introduction by Sutton and Barto, and supplemented with the YouTube series.
