File descriptions
wiki_labeled.zip
(MD5sum: 8af376e8a0f9898d8d3dd5653351070e) - the labeled dataset (in zip archive format), and should be used to train and test the model. The wiki_labeled/ directory will contains 60327 facial images kept in 100 folders, naming 00-99. Dimension of each image is 100 pixels by 100 pixels.
wiki_labeled.mat
(md5sum: d5b65bb4c4d414a230b60b8025ece276) file, containing meta information of each of the 60327 images. It contains the following information about each of the 60327 images:
ID: identification number of the subject (starting from 2002)
dob: the date of birth of the subject. (It is Matlab’s datenum value calculated based on total number of days since January 0, 0000.)
dob_str: the DD-MMM-YYYY format dob value.
photo_taken: when the photo was taken (only the year  value)
full_path: directory path, including filename of the image
gender: Gender of the subject (0: female, 1: male, NaN if unknown)
name: name of the subject
face_location: location of the face.
face_score: detector score (the higher the better). Inf implies that no face was found in the image, and the face_location then just returns the entire image.
second_face_score: detector score of the face with the second highest score. This is useful to ignore images with more than one face. second_face_score is NaN (not a number) if no second face was detected.
age: age of the person (in years), and was calculated based on the “dob” value and the “photo_taken” values.
wiki_judge_images.zip
(md5sum: 551a46ee18286824ad03d9110750da01) containing 2001 facial images (1.png, 2.png, …, 2001.png) of resolution 100x100. This is the judge/test dataset for you based on what you are going to apply your learned model to predict ages of the 2001 subjects.
wiki_judgeX.mat
(md5sum: b7382fd03b8fc05575bb5701c0eec25b) contains some meta information about the 2001 images. However, the information does not include “age” field.
sample_submission.csv
- a sample submission file in the correct format. Please disregard the values in the age field. They are all made up values.
Hint: To read/extract information from the mat file above, please use the loadmat library from scipy.io in python . [  from scipy.io import loadmat ]
