How label a cnn in keras and use mse metrics
I have to train a cnn using as loss function mse.
I normalized the labels between 0-1 but when I train I get
expected dense_2 to have shape (1,) but got array with shape (7,)
The last layer is
x = Dense(1, activation='linear')(x)
and when I…

Design Custom keras Loss Function MSE
I want to make a custom MSE loss function that uses only one item from the output layer.
What I have now is this:
def new_loss(y_true, y_pred):
index_pred = K.argmax(K.abs(y_pred), axis = -1)
pred = tf.gather(y_true, index_pred, axis = 1)

different mse result for training set
I get different results for mse. During trainig I get 0.296 after my last training epoch and when I evaluate my model I get 0.112. Does any one know why that is so?
Here is the code:
model = Sequential()
model.add(Dropout(0.2))
model.add(LSTM(100,…
