Parameters for model Training

[PratikFandade]

#history = model.fit(x, y, batch_size=16, validation_split=0,validation_data = (val_x,val_y) ,epochs = 40,callbacks = callbacks_list ,verbose=1, shuffle=True)
I have the dataset with me, i'm trying to train the model but can't get what are the x and y in the above line. Also it would be great if you tell how you have defined x and y.
Please Help
