ChallengeColor detection in fashion images
When developing new products, we analyze mass consumer trends after classifying the color of apparel from various fashion photographs. We are employing new machine learning algorithms to achieve this classification faster and more accurate.

Creating a team
Please follow these procedures to create a team.
1. All of the team members must sign up for DeepAnalytics.
2. All of the team members must agree to the Opt-in of this competition.
3. The team leader must send us the list of member's email addresses via Contact Us form.
One account per individual
You may have one account per perticipant.
If you enter as a team, only team leader's account is allowed to submit predictions.
No private sharing outside teams
Privately sharing code or data outside of teams is not permitted.
No manual labeling
You must not submit files with predictions labeled manually.
No data fabrication / falsification
You must not modify labels in the training set to train your model.
Do not edit image files
You must not edit image files with using softwares (i.e. removing background from image).
No use of external data
You must not train your model with using either external data or test data set.
Using external trained models and third party libraries
You may use the external trained models only if they are open source models (source code is provided, anyone can access, and license free).
In using external trained models, please clarify their referring source (i.e. paper link).
You may use the libraries only if they are free to use (i.e. tensorflow, chainer, and so on).
Your challenge in this competition is to detect the color on clothing featured in fashion images and classify it into 24 categories.
Please see the Download Data page for the details of submission format.
We use the metric "Balanced Accuracy" to score the submissions.
The higher submission score you get, the higher rank you will be placed in.
1. If your submission has the same score with the other participant's submission, the rank will be placed on a first-submit.
2. After the competition finished, we determine the final rankings by evaluating your submissions with different data with the one during competition.
3. We will ask you to submit the following items when determining winners.
a. The code and document of your model to reproduce the result.
b. Contribution of each feature in your classification model.
c. Execution environment (OS version, the software and modeling method that you used).
d. In your modeling with using random numbers (i.e. Random forest), please fix the seed value so that the model can be reproduced by third parties.
4. When the person or its submitted model falls under any of the following, he will lose his eligibility to receive the prize.
a. The person does not respond to the contact from us within the prescribed period.
b. Unable to reproduce the submission predictions during the competition.
c. The model lacks robustness (i.e. There are relatively more white t-shirts than yellow ones).
Guideline for modeling
Please follow the guideline below for the purpose of smooth communication upon the announcement of winning candidates.
1. Please separate your source code into 3 parts: preprocessing, training, and predicting.
a. Let's say you are coding in Python, you shall respectively code:
- preprocess.py for preprocessing
- train.py for training
- predict.py for making predictions
b. Use any languages to code your algorithms (i.e. C, Java, Lua, R, as such)
c. Sample implementation code is available. Please refer to sample_code.zip located see this page
2. Please submit your trained model as well, not only its source code.
a. We confirm if the trained model can reproduce your score on the leaderboard with using test set
3. Before submitting your code, make sure your latest submitted predictions and your local predictions match.
a. Please check the path in the test data or trained model
b. Confirm the command to execute the codes/scripts
c. Confirm if there are errors within the script (i.e. predict.py)
d. We are much appreciated if you provide your code's execution time with us
