2026/05 - Trajectory Memory for Behavior Models

@jhawkins discusses a new idea for learning behavior models. It involved trajectory memory (a sequence of movements) instead of movements in a reference frame and could be modeled in the same column as morphology. We discuss questions and implications around this idea.
Jeff also discusses a new idea around shared learning, which involves broadcasting the input from the column at the fixation point to many other columns during learning.
