Distributed and Controllable Mobile Text-to-Image Generation With User Preference Guarantee
Bibliographic record
Abstract
In this paper, we investigate controllable mobile text-to-image generation at scale, considering diverse user preferences. In particular, we observe that, by incorporating visual conditions (e.g.,Canny maps and depth maps) as supplementary inputs alongside text prompts, fine-grained and controllable image generation could be achieved. To this end, we propose a system design for distributed and controllable mobile text-to-image generation by leveraging edge computing. This system can satisfy diverse user-specified quality preferences at reduced transmission cost through effective cooperation of mobile and edge computing. In particular, the proposed system consists of aVisual Condition Engineeringmodule and aDistributed Denoising Controlmodule. Since extensive profiling reveals that different visual conditions affect both generation quality and sensitivity to image encoding parameters, the first module selects the optimal configuration of user-specific visual condition on mobile devices. Key to this module is a Pareto Frontier-based model which subtly balances user-preferred generation quality and transmission efficiency. The second module enables collaborative generation by adaptively distributing denoising tasks between mobile devices and the edge server, according to their available computing resources. At the core of this module is an efficient deep reinforcement learning algorithm designed to optimize the dynamic distribution of denoising tasks. By integrating the deep diffusion model, this algorithm achieves superior action space exploration capabilities while maintaining fast convergence and reliable execution, thereby facilitating enhanced adaptability under variable computing resource scenarios. Extensive experimental results reveal that, the designed system can achieve a reduction in transmission cost by over 90% and enhance user satisfaction by up to 18%, with consistent performance across various diffusion models under diverse resource constraints.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
