Weeds detection in dense cultures

As a part of AgTech Data Challenge!

This plant science problem is important for field robotics where the mechanical detection of weed is a current challenge to be addressed to avoid the use of phytochemical products.

 

The first part of the challenge (from 20.11.2018 to 07.01.2019) is done on restricted registration, validate according to the procedure defined by the website https://agtech-challenge.com/comment-participer/The challenge will become open to all audiences with an unlimited number of submissions.

Evaluation

The problem is a binary classification problem. Each input is a patch of an image with plants and weeds. You must classify weeds from plants. Each line represents the probabilities of class membership, which sum up to one. Preparing your submission with the starting kit is the easiest. 

There are 2 phases:

  • Phase 1: development phase. We provide you with labeled training data and unlabeled validation and test data. Make predictions for both datasets. However, you will receive feed-back on your performance on the validation set only. The performance of your LAST submission will be displayed on the leaderboard.
  • Phase 2: final phase. You do not need to do anything. Your last submission of phase 1 will be automatically forwarded. Your performance on the test set will appear on the leaderboard when the organizers finish checking the submissions.

You only need to submit the prediction results (no code). However, you need to submit a short report of 3 pages (+1 page for references) before 07.01.2019 to be eligible for the final phase. The report should be written in the CVPR template available here.

The submissions are evaluated using the mse_metric metric. This metric computes the balanced accuracy (that is the average of the per class accuracies). The metric is re-scaled linearly between 0 and 1, 0 corresponding to perfect predictions and 1 to a random guess.

Notice: Score of -1 means that there is a problem in submitted files.

Rules

Submissions must be made before the end of phase 1. You are allowed to submit 6 submissions (maximum). Your last submission of phase 1 will be automatically forwarded to phase 2

Development

Start: Nov. 22, 2018, 8 a.m.

Description: Development phase: create models and submit results (prediction) on validation and test data; feed-back are provided on the validation set only.

Final

Start: Jan. 6, 2019, 11 p.m.

Description: Final phase: submissions from the previous phase are automatically cloned and used to compute the final score. The results on the test set will be revealed when the organizers make them available.
