# Human-Action-Recognition-VIT-Base-patch16-224

This model is a fine-tuned version of [google/vit-base-patch16-224](https://huggingface.co/google/vit-base-patch16-224) on [Bingsu/Human_Action_Recognition](https://huggingface.co/datasets/Bingsu/Human_Action_Recognition) dataset.  
It achieves the following results on the evaluation set:
- Loss: 0.4005
- Accuracy: 0.8786

## Model description

The Vision Transformer (ViT) 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.

Images are presented to the model as a sequence of fixed-size patches (resolution 16x16), which are linearly embedded. One also adds a [CLS] token to the beginning of a sequence to use it for classification tasks. One also adds absolute position embeddings before feeding the sequence to the layers of the Transformer encoder.

By pre-training the model, it learns an inner representation of images that can then be used to extract features useful for downstream tasks: if you have a dataset of labeled images for instance, you can train a standard classifier by placing a linear layer on top of the pre-trained encoder. One typically places a linear layer on top of the [CLS] token, as the last hidden state of this token can be seen as a representation of an entire image.

## Intended uses & limitations

You can use the model for image classification.

### How to use

Here is how to use this model to classify an image of the human action into one of the following categories:  
calling, clapping, cycling, dancing, drinking, eating, fighting, hugging, laughing, listening_to_music, running, sitting, sleeping, texting, using_laptop

```python
from transformers import pipeline
from PIL import Image
import requests

pipe = pipeline("image-classification", "rvv-karma/Human-Action-Recognition-VIT-Base-patch16-224")
url = "https://images.pexels.com/photos/175658/pexels-photo-175658.jpeg?auto=compress&cs=tinysrgb&dpr=1&w=500"
image = Image.open(requests.get(url, stream=True).raw)
pipe(image)

# Output:
# [{'score': 0.9918079972267151, 'label': 'dancing'},
#  {'score': 0.00207977625541389, 'label': 'clapping'},
#  {'score': 0.0015223610680550337, 'label': 'running'},
#  {'score': 0.0009153694845736027, 'label': 'fighting'},
#  {'score': 0.0006987180095165968, 'label': 'sitting'}]
