I would like to check if my understanding in organizing my folders and labeling is correct regarding Caffe's way of doing it.
My train directory structure looks like below:
~/Documents/software_dev/caffe/data/smalloffice/images/train
a_person
not_a_person
train.txt
where both a_person and not_a_person are directories.
My train.txt file looks like below:
train.txt:
----------
not_a_person/1_rotated.jpg 0
not_a_person/2_rotated.jpg 0
not_a_person/3_rotated.jpg 0
not_a_person/4_rotated.jpg 0
not_a_person/5_rotated.jpg 0
...
...
...
a_person/947_rotated.jpg 1
...
...
...
Likewise, my val directory structure looks like below:
~/Documents/software_dev/caffe/data/smalloffice/images/val
a_person
not_a_person
val.txt
where both a_person and not_a_person are directories.
My val.txt file looks like below:
val.txt:
--------
not_a_person/1_rotated.jpg 0
not_a_person/2_rotated.jpg 0
not_a_person/3_rotated.jpg 0
...
...
...
a_person/152_rotated.jpg 1
...
...
...
Referring to to ilsvrc12, the content of train.txt and val.txt (hence, its structure) is as follows:
train.txt:
----------
n01440764/n01440764_10026.JPEG 0
n01440764/n01440764_10027.JPEG 0
n01440764/n01440764_10029.JPEG 0
n01440764/n01440764_10040.JPEG 0
...
...
...
val.txt:
--------
ILSVRC2012_val_00000001.JPEG 65
ILSVRC2012_val_00000002.JPEG 970
ILSVRC2012_val_00000003.JPEG 230
ILSVRC2012_val_00000004.JPEG 809
...
...
...
What has confused me is actually as opposed to what is structured in ilsvrc12, the val directory contains no subdirectories i.e. contains no grouping. Is there any effect on my classification? I am stuck at getting an accuracy which is constant of 0.5 (see here) which triggers me to check if I performed correctly regarding the labeling and folder structure.
Any hints and suggestions are welcome.
