Apparent Personality Analysis: First Impressions

Please consider downloading the data in the section Get Data before the evaluation.

 

Evaluation

The evaluation consists of computing the mean accuracy among the video tested for the 5 traits between the predicted continuous values and the continuous ground truth values.

If you want to test your method locally to see your results before submitting them, you can download the evaluation script here.

The file evaluateTraits.py perform the evaluation between the predictions produced by the participants methods and the ground-truth.

 

Once participants train their models, each video sample should output 5 continuous prediction values between the range [0, 1] corresponding to each trait. Then, participants may want to use the function in the script generatePredFile.py to generate their output predictions into a CSV file, which must have the same format as the ground-truth CSV file and is stored at:

>>> ./output/pred/predictions.csv

You can find an example of this file here. Thus, the predictions file that participants generate for the submission with their computed scores must have the same video names and number of entries in the same order as the example predictions file provided. So participants may want to use the example file as a reference of the ground-truth file for generating their predictions file in the proper format for submission, by replacing it to:

>>> ./data/gt/validation_gt.csv

 

Then, you can test your results using the script evaluateTraits.py. It reads the CSV files for the predictions and ground-truth and performs the evaluation. The resulting output is a list of 5 elements, which refer to the mean accuracies among all videos for each Big Five personality traits.

For each trait and a given video, the accuracy is computed simply as 1 minus the absolute distance among the predicted value and the ground truth value. The mean accuracy among all Big Five traits is also computed.

Note that the predictions should be in the same order as the ground-truth, so the first column of the CSV files should be identical both for the predictions and the ground truth.

Taking the last point into account, the main function of the script evaluateTraits.py can consider the different ground-truth files for the different data subsets as:

>>> gt = np.asarray(readScores("./data/gt/training_gt.csv"))

>>> gt = np.asarray(readScores("./data/gt/validation_gt.csv"))

>>> gt = np.asarray(readScores("./data/gt/test_gt.csv"))

For submitting the results, you just have to provide a ZIP file containing:

• The predictions.csv file, that can be generated with the above script generatePredFile.py, both for the validation and test phases,
• A readme.txt file containing any description you want about the code you provide (GitHub link, running scripts, etc.).

Take in mind that the better your descriptions are, the better you will be rated by other participants and you will get more downloads!

Enjoy it!

Official rules

https://docs.google.com/document/d/1hOhiy1ken9iOsxB7lknCdRUxI8YtwnU7dKgyciY-aMM/edit

Common terms used in these rules:

 

These are the official rules that govern how the Joint Contest on Multimedia Challenges Beyond Visual Analysis contest promotion will operate. This promotion will be simply referred to as the “contest” or the “challenge” throughout the rest of these rules and may be abbreviated on our website, in our documentation, and other publications as ChaLearn LAP.

In these rules, “organizers”, “we,” “our,” and “us” refer to CHALEARN and MS refer to Microsoft; "participant”, “you,” and “yourself” refer to an eligible contest participant.  

 

1. Contest description

This is a skill-based contest and chance plays no part in the determination of the winner(s). The goal of the contest is recognizing apparent personality traits from short video clips, the challenge is called first impressions.

 

1. Focus of the Contest: It will be made available a newly collected dataset of at least 10,000 15-second videos collected from YouTube, annotated with personality traits by AMT workers. The traits will correspond to the “big five” personality traits used in psychology and well known of hiring managers using standardized personality profiling: extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience. Ground truth was generated by using crowd sourcing (AMT) on the basis of a rigorous methodology. Participants will have to develop automatic methods for recognizing the traits as given by the ground truth. This is a second round of the first impressions challenge that was part of workshops program at ECCV 2016. For this second round, the challenge will adopt a coopetitions scheme in which participants will be encouraged to share their code with other participants. Therefore there are two scores considered in the coopetition: (1) the accuracy of prediction and (2) the number of downloads of the code. The ranking score is the average of the ranks that people get with score (1) and score (2).
2. All eligible entries received will be judged using the criteria described below to determine winners.

 

2. Tentative Contest Schedule

The registered participants will be notified by email of any change in the schedule.
