# Exact-architecture comparison using the authors' canonical two-hidden-layer
# EP protocol: 784-500-500-10, 60 epochs, batch size 20, 150 free steps,
# 6 nudged steps, beta 1, and layer rates [0.4, 0.1, 0.01].

# BP/DFA/SDIL use the identical forward architecture, first 50k MNIST
# training examples, and 60 epochs, while retaining their native feedforward
# preprocessing and dynamics.
