Keras Extremely High Loss

Question

I\'m trying to predict price by characteristics. I chose a pretty simple model, but it works very strange. Loss function is extremely high and I can\'t see where the problem

Answer 1

As @Yu-Yang said you are using mean squared error as loss function. I had this same problem before where the loss value will be very large, on changing the loss function to mean_squared_logarithmic_error, I got the desired result.

model %>% compile(
optimizer = optimizer_rmsprop(lr=0.0001),
loss = loss_mean_squared_logarithmic_error,
metrics = c("accuracy")
)

The loss value changed to

Epoch 1/10
326981/326981 [==============================] - 17s - loss: 0.0048 - acc: 0.9896

Hope this finds useful !
