relu6

std.elementwise.relu6 · Level L1

ReLU capped at 6, as in mobile networks.

min(relu(x), 6)

Signature

relu6(x: f64[n]) → f64[n]

Structure

The function as NOVA stores it: one box per input, operation and output, and arrows that carry values. A double border marks a call to another library function; select it to open that function.

Verification

  • Signature proven by NOVA’s shape solver, for every size.
  • Equal to the reference np.minimum(np.maximum(x, 0), 6) in exact rational arithmetic, on all 40 test cases.
  • All 159 float64 results are exact: the error is zero.
  • Interpreter and NumPy backend return bit-identical results.
