Training and validation loss curve remains flat when trained on MVTec data #63
Description
Greetings,
I trained the network on MVTEC tile data (Tried on various other datasets as well). The details are as follows
Command
python <Root folder>/train.py -d <data folder>/capsule -a mvtecCAE -l ssim -b 32
config.py
ROT_ANGLE = 5
W_SHIFT_RANGE = 0.05
H_SHIFT_RANGE = 0.05
FILL_MODE = "nearest"
BRIGHTNESS_RANGE = [0.95, 1.05]
VAL_SPLIT = 0.2
# Learning Rate Finder parameters
START_LR = 1e-7
LR_MAX_EPOCHS = 10
LRF_DECREASE_FACTOR = 0.85
# Training parameters
EARLY_STOPPING = 12
REDUCE_ON_PLATEAU = 6
# Finetuning parameters
FINETUNE_SPLIT = 0.1
STEP_MIN_AREA = 5
START_MIN_AREA = 5
STOP_MIN_AREA = 1005

Additional info
I am getting similar results on all other cases in Mvtec dataset too.
Having other questions like why is val loss less than training loss, etc.
I am getting a feeling that I am not setting something right.
Kindly help.
