JCAM Highlights — “Stochastic gradient algorithms from ODE splitting perspective”

JCAM requirement: 3–5 bullets, max 85 characters each (plain text, no math symbols).

Highlights (char-count verified 2026-03-18)

# Plain-text highlight Chars
1 SGD reinterpreted as Lie-Trotter operator splitting of gradient-flow ODE 72 ✓
2 Higher-order local ODE solvers yield step-size-robust splitting optimisation 76 ✓
3 Kaczmarz method is the exact unit-batch splitting limit for linear least squares 80 ✓
4 Lie-Trotter ISTA: zero asymptotic bias; Strang-ISTA has O(h²λ²) bias floor 75 ✓
5 Strang-ISTA support conjectured: j in supp iff |d_j|>λ/2; numerically confirmed 82 ✓

Note: H5 updated to Conjecture C version (18 мар); replaces old “Bias floor scaling…” bullet.

⚠️ Fix required in main_jcam.tex before JCAM submission

Highlight #4 in current tex file is 88 chars plain-text → EXCEEDS 85. Fix:

Current (88 chars plain-text):

\item Lie--Trotter ISTA has zero asymptotic bias; Strang-ISTA incurs $O(h^2\lambda^2)$ bias floor

Replace with (75 chars):

\item Lie--Trotter ISTA: zero asymptotic bias; Strang-ISTA has $O(h^2\lambda^2)$ bias floor
