Source-bound correction: Join wrapped printed heading text using adjacent source lines; original heading start coordinates are unchanged.
Section-by-section lengths and source pages
The title/abstract/front matter precede the first numbered heading. A span ends at the next detected top-level heading, not at the last sentence; end-page whitespace is included. References and statements are listed separately. These are not measurements of text-only or artwork area.

Argument and organization
- 1 Introduction; 2 Setup; 3 Dynamics
Defines the Gaussian model and converts joint function/direction learning into coupled spectral dynamics.
- 4 Convergence; 5 Kernel Implementation
Contrasts fixed-profile and joint learning, gives a three-phase proof sketch and builds a finite-dimensional realization.
- 6 Numerical Experiments; 7 Outlook
Separates idealized ODE simulations from finite-sample empirical dynamics and leaves sample complexity open.
Problem, claim and contribution
The opening makes joint learning of direction and profile the object of study, with negative initial correlation motivating the fixed-versus-adaptive comparison.
Abstract and Introduction, p.1; Section 4.1, p.4 · Main paper
Argument and section order
A numbered fast–slow–convergence explanation follows the formal theorem and precedes practical implementation.
Section 4.3, p.6 · Main paper
Figures, captions and visual explanation
The idealized figure pairs phase portraits with time traces; the empirical figure plots every seed in two sign groups, explicitly avoiding averages that would smear transition times.
Figures 1-2, pp.7-8 · Main paper
Tables, comparisons and evidence
The finite-data caption supplies sample size, dimension, truncation and seed count, while the text discloses controlled initialization rather than presenting it as unmodified random initialization.
Section 6 and Figure 2, p.8 · Main paper
Appendix and reproducibility
The deferred derivation restates the gradient-flow system and connects the function-space gradient to the coefficient equations used in the main argument.
Appendix A.2, p.12 · Main paper
Clarity and writing conventions
The conclusion states that sample complexity and discrete finite-data guarantees remain future work, separating qualitative numerical agreement from the population theorem.
Conclusion and Outlook, p.9 · Main paper
What to reuse—and what not to infer
Transferable lesson: Choose a display that preserves the theoretical phenomenon and explain why a familiar summary statistic would obscure it.
Boundary: The guarantee concerns idealized population gradient flow under the stated Gaussian and regularity assumptions, not a finite-sample learning bound; this scan does not validate proofs.
Apply this lesson using the argument and evidence worksheet.
