I\'m running the LSTM model for the first time. Here is my model:
opt = Adam(0.002)
inp = Input(...)
print(inp)
x = Embedding(....)(inp)
x = LSTM(...)(x)
x = Bat
The order of details provided with verbose flag are as
Less details.... More details
0 < 2 < 1
Default is 1
For production environment, 2 is recommended
Check documentation for model.fit here.
By setting verbose 0, 1 or 2 you just say how do you want to 'see' the training progress for each epoch.
verbose=0
will show you nothing (silent)
verbose=1
will show you an animated progress bar like this:
verbose=2
will just mention the number of epoch like this:
For verbose
> 0, fit
method logs:
Note: If regularization mechanisms are used, they are turned on to avoid overfitting.
if validation_data
or validation_split
arguments are not empty, fit
method logs:
Note: Regularization mechanisms are turned off at testing time because we are using all the capabilities of the network.
For example, using verbose
while training the model helps to detect overfitting which occurs if your acc
keeps improving while your val_acc
gets worse.
By default verbose = 1,
verbose = 1, which includes both progress bar and one line per epoch
verbose = 0, means silent
verbose = 2, one line per epoch i.e. epoch no./total no. of epochs
verbose: Integer
. 0, 1, or 2. Verbosity mode.
Verbose=0 (silent)
Verbose=1 (progress bar)
