Sports Activity Recognition using Transfer Learning
Objective: Build a knn-classifier to recognize sports activities using Transfer Learning..
Why Transfer Learning? While pre-trained models are great for recognizing cats & dogs, or cars & trucks, here, I show you how to customize a pre-trained model for a new task in 3 simple steps.
- Compile a training video to demonstrate various activities you want to capture automatically using Transfer Learning
- For each activity, capture few screenshots and tag them manually to train the classifier
- Run predictions to recognize activities in the new test-video
Because the pre-trained model (used for feature extraction) is already trained on a very large dataset, the classifier achieves decent accuracy even though the new training sample used for customization is relatively much smaller in size.
