A doubt
I would like to ask, in your dataset, each video folder contains 24 video files. Are all 24 of these videos fake? Because in your paper, you mentioned that there are 15 real ones and 9 fake ones. The same question applies to the audio folders. I look forward to your reply.
After the interview, the subject were asked to rate the answer they just lied to. The same score is 1-5, where 1 represents that I have definitely deceived successfully and 5 represents that I have definitely not deceived successfully ("Self evaluation of interviewee" in "deception/lables/xxx.csv", and 0 indicates that the question is not a deceptive problem).
More details can be found in "MDPE dataset description. docx"
Thank you for your reply. Can I understand that a video labeled 0 represents the subject lying, and a video labeled non-0 represents the subject telling the truth? I hope you can help me clarify this, I would be very grateful!
On the contrary, 0 in 'Self evaluation of interviewees' represents the subject telling the truth and non-0 represents the subject lying.
Thank you for your detailed reply. If I may, I would like to ask what model you used when extracting features from the data. I'm planning to use your dataset to build a system for detecting deceptive behavior, and I would appreciate your guidance on the approach.
