## Keras Implementation of Video Vision Transformer on medmnist | |
This repo contains the model [to this Keras example on Video Vision Transformer](https://keras.io/examples/vision/vivit/). | |
## Background Information | |
This example implements [ViViT: A Video Vision Transformer](https://arxiv.org/abs/2103.15691) 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](https://medmnist.com/) dataset. | |
