Grandmaster Series – How to Perform Large-Scale Image Classification

In episode two of the Grandmaster Series, learn how participating members of the Kaggle Grandmasters of NVIDIA (KGMON) built large-scale image classification models to win the Google Landmark Recognition 2020 Kaggle competition. 

In this landmark recognition challenge, the team had to build models that recognize the correct landmark (if any) in a dataset of complicated test images. This is easier said than done, given landmark recognition contains a much larger number of classes. For example, there were more than 81,000 classes in this competition. Watch the video to learn how more!
