Decoding Input-Adaptive Generative Dynamics in Diffusion Models
This paper introduces a novel approach to diffusion models, moving beyond fixed denoising trajectories to embrace input-adaptive generative dynamics. The proposed framework, Adaptively Controllable Diffusion (AC-Diff), dynamically adjusts the diffusion horizon and noise schedule based on individual sample requirements. By training the diffusion backbone with an adaptive sampling strategy, AC-Diff achieves consistent performance across varying input-adaptive trajectories. Experiments on conditional image generation, specifically CIFAR-10, demonstrate that AC-Diff maintains high generation quality while significantly reducing the average number of sampling steps. These results provide compelling evidence that diffusion processes greatly benefit from dynamic, input-adaptive generative dynamics rather than static, fixed trajectories, offering a more efficient and adaptable solution for complex generation tasks.

Introduction
The introduction highlights the limitations of conventional diffusion models, which use a fixed denoising trajectory for all samples, regardless of their complexity. It proposes the concept of input-adaptive generative dynamics where the generation process adjusts to individual input requirements. The paper aims to develop a framework that allows diffusion dynamics to vary across inputs, optimizing efficiency and quality.
Methodology
This section details the Adaptively Controllable Diffusion (AC-Diff) framework. It includes mechanisms for conditional diffusion horizon estimation (CTS Module) to predict the required diffusion length per sample, and adaptive noise dynamics (AHNS Module) to adjust the noise schedule. The model is trained with an adaptive sampling strategy, exposing the network to varying diffusion trajectories to ensure robustness.
Experiments
Experiments on conditional image generation using CIFAR-10 demonstrate AC-Diff's effectiveness. Evaluation metrics include FID, CLIP-based scores (CS-t2i, CS-i2i), and CLIP Aesthetic Score, alongside efficiency metrics like Average Diffusion Time-Steps. Results show competitive generation quality with significantly fewer sampling steps, validating the benefits of input-adaptive dynamics. Ablation studies further confirm the contributions of conditional training and adaptive scheduling.
Conclusion
The paper concludes that input-adaptive generative dynamics improve sampling efficiency while maintaining high generation quality for conditional image generation. By dynamically adjusting the diffusion horizon and noise schedule, AC-Diff avoids unnecessary steps, especially for simpler samples. Future work will extend this approach to more complex datasets and broader conditional generation tasks.
Enterprise Process Flow
Conventional diffusion models use a single fixed trajectory for all samples, leading to inefficiency for simpler tasks. AC-Diff introduces input-adaptive trajectories that dynamically adjust the diffusion horizon and noise schedule per input, optimizing for varying complexity.

Significant Reduction in Sampling Steps
AC-Diff achieves significant efficiency improvements by dynamically adjusting the diffusion trajectory length, reducing the average number of sampling steps from 1000 (DDPM* cond f.&r.) to 141 while maintaining generation quality. This represents a substantial gain in computational efficiency for enterprise applications.

Impact of Adaptive Noise Scheduling
The study highlights the importance of adaptive noise scheduling. Compared to a fixed downsampled schedule, the proposed Adaptive-β strategy significantly improves generation quality (lower FID, higher C-Aes.), demonstrating the necessity of adjusting noise dynamics according to the adaptive trajectory for optimal results.

Benefits of Conditional Training in Diffusion Models
The research rigorously demonstrates that integrating conditional information directly during both training and generation (e.g., DDPM* cond f.&r.) significantly enhances model performance and stability. This contrasts with approaches that inject conditions only during generation (e.g., DDPM cond r.), which show limited improvements and can lead to unstable results.
By allowing the model to learn conditional guidance throughout the training process, it better exploits provided text prompts and structural cues. This leads to more stable conditional alignment and superior visual quality, proving that a holistic conditional training strategy is crucial for building robust and high-performing generative AI systems in an enterprise context.
