Viligance/ISA-Vision

ISA Vision checkpoints

Model-only PyTorch checkpoints for the ISA vision experiments. The repository contains CIFAR-100 and ImageNet-200 checkpoints for hybrid and physical models at tiny, mid, and small scales.

Device equation

The physical operator evaluates

[ I(V,V_{th}) = I_S\frac{\operatorname{softplus}^2!\left(\frac{V-V_{th}}{2nU_T}\right)-\operatorname{softplus}^2!\left(\frac{V-V_{th}-V_D}{2nU_T}\right)}{1+V/V_{sat}}. ]

The checkpoint tensors already contain the fitted threshold and TIA parameters required by this operator.
