exponential(X, a, b)

Exponential kernel function.

\[y = \exp(a + b \cdot X)\]

Parameters:

• X (array-like) – Input data.

• a (float) – Coefficient for the constant term inside the exponential.

• b (float) – Coefficient for the linear term inside the exponential.

Returns:

Exponential of the linear function.

Return type:

array-like
