[P] Morphic Activation: A C1-Continuous Polynomial Alternative to Swish/GELU for Efficient Inference
I’ve been exploring the “Inference Paradox”—the performance gap between transcendental-heavy activations (Swish/GELU) and hardware-efficient but jagged approximations (HardSwish). I am sharing SATIN-U (Smoothstep-Activated Trainable Inference Network), which utilizes a cubic polynomial bridge to achieve Swish-like fidelity without the exponential math tax. The Implementation Logic: The goal was to maintain a differentiable path while ensuring an absolute zero floor for hardware-level sparsity (clock gating). The Math: u = clamp(0.5 + 0.5 * (x / b), 0, 1) gate = […]
