WP2 — PI-VIB-ResNet Model Design
Lead: Sejong University (SJU) — AINTLab — Prof. Syafrudin
Timeline: M4 – M14
Key milestone: M10 — First trained PI-VIB-ResNet model; M14 — Ablation study complete
Objectives
- Design and implement the PI-VIB encoder with physics consistency loss
- Train ResNet-BPNN regressor on WP1 T-EV field data
- Conduct systematic ablation studies to validate each architectural component
Architecture Components
VIB Encoder
- Input: 51-point impedance spectrum (real + imaginary parts → 102 features after wavelet denoising)
- Encoder: 3-layer MLP → (μ, log σ²) → reparameterization → latent z ∈ ℝ^32
- Physics loss: Randles circuit consistency constraints
ResNet-BPNN
- 12–18 residual blocks (2-layer each)
- Batch normalization + dropout (p=0.2)
- Output: scalar SOH ∈ [0, 100]%
