# Goals and Outcomes # Goals and Outcomes
# Research Methodology # Research Methodology
### **Slide 1: Research Motivation**
**Assertion:** Current methods for generating unstructured perturbations are limited in flexibility and generalizability.
- **Evidence:**
- Unstructured perturbations lack adaptability to various scenarios.
- Proposed approach leverages diffusion generative models for flexible perturbation generation.
**Visuals:**
- A flowchart contrasting traditional perturbation methods vs. diffusion models.
---
### **Slide 2: Diffusion Model Features**
**Assertion:** Frequency response data forms the foundation for feature creation in diffusion models.
- **Evidence:**
- Features discretize dynamics into a vector of magnitude and phase.
- Supports training without imparting unintended structure.
**Visuals:**
- Diagram from Figure 1 showing the discretization of frequency response.
---
### **Slide 3: Creating Frequency Features**
**Assertion:** Discretizing the frequency response enables scalable feature sets.
- **Evidence:**
- Fine resolution for complex behavior or coarse for computational efficiency.
- Features provide physical context across frequency scales.
**Visuals:**
- Table comparing fine vs. coarse frequency sampling.
- Annotated example of magnitude/phase vector with scales labeled.
---
### **Slide 4: Training the Diffusion Model**
**Assertion:** Diffusion models learn unstructured perturbations through iterative noise transformation.
- **Evidence:**
- Forward process adds noise; reverse process removes it.
- Training maximizes log-likelihood between input and reconstructed data.
**Visuals:**
- Flowchart of the diffusion training process.
- Key equations (e.g., Eq. \ref{forward_kernel} and \ref{reverse_kernel}) simplified with annotations.
---
### **Slide 5: Generating New Perturbations**
**Assertion:** The trained diffusion model generates diverse and flexible perturbations.
- **Evidence:**
- Outputs are probabilistic, enabling variability.
- Perturbation level controlled by adjusting time steps.
**Visuals:**
- Illustration of forward/reverse process with arrows and annotations.
- Graph showing interpolation from partial time steps.
---
### **Slide 6: Ensuring Valid Perturbations**
**Assertion:** Generated perturbations must meet robust control requirements.
- **Evidence:**
- No additional right-hand plane poles.
- Supremum gain of Δ below threshold β.
**Visuals:**
- Diagram of pole-zero constraints.
- Workflow for verifying Δ and fitting transfer functions.
---
### **Slide 7: Advantages of Diffusion Models**
**Assertion:** Diffusion models provide a novel solution for generating unstructured perturbations.
- **Evidence:**
- Introduce non-deterministic variability into perturbations.
- Overcome the limitations of traditional structured approaches.
**Visuals:**
- Comparative chart: structured vs. unstructured methods.
- Examples of perturbed frequency responses generated by the model.
