How to write masked MSE loss in Keras?
I was trying to write masked MSE loss:
def mae_loss_masked(mask):
def loss_fn(y_true, y_pred):
abs_vec = tf.multiply(tf.abs(y_pred-y_true), mask)
loss = tf.reduce_mean(abs_vec)
return loss
return loss_fn
My model:
def MobileNet_v1():
# MobileNet with dense layer on top
# Keras 2.1.6
mobilenet = MobileNet(input_shape=(config.IMAGE_H, config.IMAGE_W, config.N_CHANNELS),
alpha=1.0,
depth_multiplier=1,
include_top=False,
weights='imagenet'
)
x = Flatten()(mobilenet.output)
x = Dropout(0.5)(x)
x = Dense(config.N_LANDMARKS * 2, activation='linear')(x)
# -------------------------------------------------------
model = Model(inputs=mobilenet.input, outputs=x)
optimizer = Adadelta()
model.compile(optimizer=optimizer, loss=mae_loss_masked)
model.summary()
import sys
sys.exit()
return model
But it give an error:
TypeError: mae_loss_masked() takes 1 positional argument but 2 were given
Also a question how batch generator output should look like in this case.
python tensorflow keras deep-learning mse

Your loss function takes 1 argument, while you are actually giving it 2. using mae_loss_masked(some_mask) will get you the actual loss function you need: stackoverflow.com/questions/46858016/… , batch should still be (x,y) , or optionally (x,y, weights)
