  "title": "Phase-HDC: Replacing Optimizer History with Gradient Thresholds in Discrete Phase Learning",
  "summary": "Phase-HDC replaces the optimizer's gradient history (Adam moments) with a memoryless rule that moves each low-bit angle at most one step against the current gradient's sign only when the gradient exceeds a threshold. The cost is an average loss of roughly five accuracy points versus float32 Adam, and the savings are reported as logical state counts rather than measured hardware memory. The method applies only to hyperdimensional classifiers with low-bit quantized phase parameters, and it can fail where the five-point accuracy gap is unacceptable or where the model family itself does not fit the task.",
  "rationale": "The storage reduction is substantial but the technique is restricted to discrete phase-memory HDC models, a model family the reader does not currently operate, and the accuracy penalty against full-precision Adam limits its production value outside that niche.",
