Welcome! In this competition, the competitors are asked to submit a python function whose input is a trained neural network and its training data and output is a complexity measure or generalization predictor that quantifies how well the trained model generalizes on the test data. You can find general information of the competition at https://sites.google.com/view/pgdl2020/.
You can get a starting kit which contains a sample submission in the get_starting_kit tab to the left. You can also download sample data that we have prepared, but you are not obligated to use them (since they are not drawn from the same distribution as the test data). The starting kit already contains a sample submission that can be submitted. In addition, the starting kit also contains a number of example baselines that demonstrate how to effectively use the API's, if you are not familiar with Keras. When testing locally, please make sure that you are using Tensorflow 2.2. If you are familiar with Docker, it would be good to test the code in our docker environment to make sure everything runs correctly. Alternatively, we prepared a Colab notebook where you can test whether your submission runs correctly on a single model without the need for setting up all software dependencies.
You are expected to form teams; however, there are no minimum or maximum number for how many participants are allowed on each team. Each participant should only be on one team. Teams will be approved by organizers but you may add team members later. For more details, check https://github.com/codalab/codalab-competitions/wiki/User_Teams. If you have potential conflict of interests with the organizing teams and are thus not eligible for winning the competition, please apply to join the team COI or create a team with the COI prefix (e.g. COI-Google).
To make a submission, click on the Participate tab above, then select Submit/View Result tab on the left, and finally click on the Submit button to upload your submission. If you are new to Codalab and wants to learn more, please check https://github.com/codalab/codalab-competitions/wiki for more information about how to use the platform.Note: Please make sure you have a metadata in your submission. Otherwise Codalab would not recongnize your submission. The content does not matter.
You may use the the Forums above to start discussions. You can also reach the organizers at firstname.lastname@example.org.
In this competition, the competitors are asked to write a Python function whose input is a trained neural network and its training data and output is a complexity measure or generalization predictor that quantifies how well the trained model generalizes on the test data. The competition will be separated into 2 phases: development phase and evaluation phase each with its own set of neural networks. Please make sure in the submission there is a python script called complexity.py and inside there is a function called complexity that takes in a Keras model and Tensorflow dataset and outputs a scalar value that is your solution.
The competitors can only submit a fixed number of solutions everyday and the submission must finish within a given time budget. In the evaluation phase, the competitors have a limited number of chance to submit new solutions. The solutions in this phase are first run on development phase data to make sure that it finishes within time budget.
There are 2 phases:
The submissions are evaluated using the conditional mutual information metric outlined in this document, originally proposed in this paper. The minimum score is 0.0 and the maximum score is 1.0. We multiply the final score by 100 so the score ranges from 0 to 100.
A participant may submit 3 submissions every day and 150 in total. While there are no limit on submissions per team, please be mindful that computational resource is shared between all participants of the competition and please be reasonable and kind and refrain from submitting large numbers of submissions in parallel!
This challenge is governed by these rules. Participating in the competition means that you have read and agree with these rules.
|Starting Kit||3.850||#1 Development Phase|
|Public Data||8994.553||#1 Development Phase|
Note: Information below may be adjusted as the competition continues based on the computational demand and availability.
The submissions will be run on virtual machines with the following hardware spesc on Google Cloud:
We are allowing 3 submissions per day per team, and 150 submissions over the course of the competition. Although models differ in size, the participants submission is expected to finish on average within 5 minutes per model (amortized). Submissions exceeding this time limit will receive the minimum score.
You can find this docker image on Docker Hub. This image contains most common packages; however, if you believe there are necessary packages missing, please contact the organizing team and we will try to add your package to the best of our abilities.
If you are not familiar with docker, you make sure your local environment or virtual environemnt use Tensorflow 2.2.
During our pilot testing phase, we tested and confirmed that data augmentation is one of the easiest ways for participants to earn a high score in this competition. As one of the goals for this competition is to help researchers discover measures that can grant theoretical insight into the phenomenon of generalization in deep learning, we would like to note that, if necessary, we may create a separate track for submissions that do not use data augmentation (or other potential “exploitative” techniques), in order to encourage submissions that produce new insight into the phenomena of generalization. We also reserve the right to change the data and model during phase 1 if we learn that the competition is too exploitable.
Best of luck to everyone!
