CSATv2

CSATv2 is a lightweight high-resolution vision backbone designed to maximize throughput at 512×512 resolution.
By applying frequency-domain compression at the input stage, the model suppresses redundant spatial information and achieves extremely fast inference.

## Highlights

- 🚀 **2,800 images/s at 512×512 resolution (A6000 1×GPU)**
- ⚡ **Frequency-domain compression** for lightweight and efficient modeling
- 🎯 **80.02%** ImageNet-1K Top-1 Accuracy
- 🪶 Only **11M parameters**
- 🧩 Suitable for **image classification** or as a **high-throughput detection backbone**

This model is an improved version of the architecture used in the [paper](https://www.mdpi.com/2306-5354/10/11/1279)

Special thanks to **Demino** for contributing ideas and feedback that greatly helped in lightweighting and optimizing the model.

This model is designed primarily for image classification tasks and can also serve as a high-throughput backbone for object detection.
```python
import torch
from datasets import load_dataset
from transformers import AutoImageProcessor, AutoModelForImageClassification

# 예시 데이터: 고양이 이미지
dataset = load_dataset("huggingface/cats-image")
image = dataset["test"]["image"][0]

# 👉 CSATv2 모델로 교체
model_name = "Hyunil/CSATv2"

# Preprocessor + Model 로드
processor = AutoImageProcessor.from_pretrained(model_name, trust_remote_code=True)
model = AutoModelForImageClassification.from_pretrained(model_name, trust_remote_code=True)

# 전처리
inputs = processor(image, return_tensors="pt")

# 추론
with torch.no_grad():
    logits = model(**inputs).logits

pred = logits.argmax(-1).item()
print("Predicted label:", model.config.id2label[pred])
