City_map-vit-base-patch16-224

The fine-tuned ViT model that beats Google's state-of-the-art model and OpenAI's famous GPT4 for maps of cities around the world

Image-classification fine-tuned model that identifies which city map is illustrated from an image input.

The Vision Transformer (ViT) base model is a transformer encoder model (BERT-like) pretrained on a large collection of images in a supervised fashion, namely ImageNet-21k, at a resolution of 224x224 pixels. Next, the model was fine-tuned on ImageNet (also referred to as ILSVRC2012), a dataset comprising 1 million images and 1,000 classes, also at resolution 224x224.

Training data

This Google's ViT-base-patch16-224 for city identification model was fine-tuned on the STEM-AI-mtl/City_map dataset, contaning overer 600 images of 45 different maps of cities around the world.

Training procedure

A Transformer training was performed on google/vit-base-patch16-224 on a 4 Gb Nvidia GTX 1650 GPU.
