ProtoViT: Interpretable Vision Transformer with Adaptive Prototype Learning

This repository contains pretrained ProtoViT models for interpretable image classification, as described in our paper "Interpretable Image Classification with Adaptive Prototype-based Vision Transformers".

Model Description

ProtoViT combines Vision Transformers with prototype-based learning to create models that are both highly accurate and interpretable. Rather than functioning as a black box, ProtoViT learns interpretable prototypes that explain its classification decisions through visual similarities.

Supported Architectures

We provide three variants of ProtoViT:

ProtoViT-T: Built on DeiT-Tiny backbone
ProtoViT-S: Built on DeiT-Small backbone
ProtoViT-CaiT: Built on CaiT-XXS24 backbone

Performance

All models were trained and evaluated on the CUB-200-2011 fine-grained bird species classification dataset.

Model Version	Backbone	Resolution	Top-1 Accuracy	Checkpoint
ProtoViT-T	DeiT-Tiny	224×224	83.36%	Download
ProtoViT-S	DeiT-Small	224×224	85.30%	Download
ProtoViT-CaiT	CaiT_xxs24	224×224	86.02%	Download

Features

🔍 Interpretable Decisions: The model performs classification with self-explainatory reasoning based on the input’s similarity to learned prototypes, the key features for each classes.
🎯 High Accuracy: Achieves competitive performance on fine-grained classification tasks
🚀 Multiple Architectures: Supports various Vision Transformer backbones
📊 Analysis Tools: Comes with tools for both local and global prototype analysis

Requirements

Python 3.8+
PyTorch 1.8+
timm==0.4.12
torchvision
numpy
pillow

Limitations and Bias

Data Bias: These models are trained on CUB-200-2011, which may not generalize well to images outside this dataset.
Resolution Constraints: The models are trained at a resolution of 224×224; higher or lower resolutions may impact performance.
Location Misalignment: Same as the CNN based models, these models are not perfectly immune to location misalignment under adversarial attack.
