This video demonstrates how to use LandingLens to train a computer vision model for a multiclass classification project using an open-access retinopathy of prematurity dataset. It covers the end-to-end process, including data preparation, model training with custom augmentations, performance evaluation, and deploying the model for API-based inference. LandingLens achieves a F1 score of 92 on the test set as compared to 83 published by the original authors that provided the data.
