Question About Batch_size and Epoch

[EmirhanToprak]

Hi, i implemented the code to my dataset.
I have 360 video in total for 2 class (270 training 90 for validation).
I select the "sample duration" = 32

I didn't quite understand the batch size and epoch.
When i set batch_size = 12, training dataset for per epoch = 270/12 = 23 video

• So, the batch size is, from 23 video, select 12 frame and train?

• This selected 23 video, is it selected randomly per epoch from 270 video? or is it the same 23 video for full 200 epoch training?

Can anyone explain please? Thank you.

The opts.py i selected
parser.add_argument('--sample_size',
default=224,
type=int,
help='Height and width of inputs')
parser.add_argument('--sample_duration',
default=32,
type=int,
help='Temporal duration of inputs')
parser.add_argument('--batch_size',
default=12,
type=int,
help='Batch Size')
parser.add_argument('--n_val_samples',
default=12,
type=int,
help='Number of validation samples for each activity')
