Web2 okt. 2024 · model= keras.Sequential([ keras.layers.Dense(units=90, activation=keras.layers.LeakyReLU(alpha=0.01)) ]) However, passing 'advanced activation' layers through the 'activation' argument of a layer is not a good practice and is best to be avoided. Refer to the Official Docs for more - Layer Activation Functions. … can i have new lenses fitted in my old framesWebEdit. A Parametric Rectified Linear Unit, or PReLU, is an activation function that generalizes the traditional rectified unit with a slope for negative values. Formally: f ( y i) = y i if y i ≥ 0 f ( y i) = a i y i if y i ≤ 0.
