Product Detection
Detect Real Product On E-commercial Platform
Background

Task
In this competition, a multiple image classification model needs to be built. There are ~100k images within 42 different categories, including essential medical tools like masks, protective suits and thermometers, home & living products like air-conditioner and fashion products like Tshirts, rings, etc. For the data security purpose the category names will be desensitized. The evaluation metrics is top-1 accuracy.

Dataset Description
In Shopee Product Detection Dataset, there are more than 100k images directly from the Ecommercial industry field. You will be able to explore the real-world images which is noisy and long-tailed, and let your model predict the correct categories for the images.

File descriptions
– train.csv: training dataset. – test.csv: test dataset.
Columns of data fields
– filename: image file name(str). – category: image category(str).

Please download the dataset from the folder.

Evaluation criteria
Submissions are scored on top-1 precision:
𝑁
𝑠𝑐𝑜𝑟𝑒 𝑝(𝑥𝑖, 𝑦𝑖)
𝑖=0
Where
– N is number of test samples.
– xi is the predicted category for i th test sample.
– yi is the ground truth for i th test sample.
– p(xi,yi) is calculated as 1 if xi=yi and 0 otherwise.
A higher score is better. In your practice you need to find a proper threshold to predict category name(string) instead of probabilities.

Submission File
Submission file format should be `csv` file only. And for each `filename` in the test dataset, you must predict only one proper category name. The `csv` file should contain a header and have the following format:
