Keras Implementation of Video Vision Transformer on medmnist
This repo contains the model to this Keras example on Video Vision Transformer.
Background Information
This example implements ViViT: A Video Vision Transformer by Arnab et al., a pure Transformer-based model for video classification. The authors propose a novel embedding scheme and a number of Transformer variants to model video clips.
Datasets
We use the MedMNIST v2: A Large-Scale Lightweight Benchmark for 2D and 3D Biomedical Image Classification dataset.
