Struct GradientDirection

Direction and characteristics of gradient flow

Fields

step: usize

norm_delta: f64

Signed change in gradient norm vs. the previous recorded step (norm(step) - norm(step - 1); 0.0 on the first step, where there is no previous value to compare against). Positive means the norm grew, negative means it shrank. This is a real, computed trend indicator – not a per-parameter gradient direction vector: GradientHistory retains only reduced per-step statistics (norm/mean/std), so a true high-dimensional direction is not available here. Previously misnamed direction_vector and set to vec![norm], which duplicated magnitude rather than carrying any directional information.

magnitude: f64

consistency_score: f64
