Advancement in image processing and machine learning algorithms have allowed us to accurately detect and classify objects with a high degree of precision. Can this technology be extended to images related to food recipes?  In Rakuten Deep Learning Challenge, we are asking you to classify food images into different categories. This will enable better taxonomy and improved indexing for search operations. We bring you hundreds of thousands of images from Rakuten Recipe - Rakuten's haven for food lovers, home chefs and really just anyone with an empty stomach and an appetite for new flavors. 

The challenge is to develop an algorithm that would classify a given recipe food image into one of the pre-defined categories with high precision and recall. The labeled dataset is provided for supervised training and mapping to different food categories. 

Rakuten Deep Learning Challenge is hosted by Rakuten Institute of Technology Bengaluru (India), a dedicated R&D wing of Rakuten Inc.

Data - The Rakuten recipe food image data is distributed across 43 categories with around 0.79 million images. Each image category is prepared according to their Recipe, time taken to prepare it and it's ingredients etc. 

DISCUSSION: Join the slack channel for discussions and communications regarding the challenge.
