### Model Description
|
| 17 |
+
A machine learning model for crowd counting
|
| 18 |
+
|
| 19 |
+
- **Developed by:** rootstrap
|
| 20 |
+
- **Model type:** image-classifier
|
| 21 |
+
- **License:** mit
|

+
## Crowd Counting Model
|
| 24 |
+
The aim is to build a model that can estimate the amount of people in a crowd from an image-
|
| 25 |
+
|
| 26 |
+
The model was built using **CSRNet** a crowd counting neural network designed by Yuhong Li, Xiaofan Zhang and Deming Chen ([https://github.com/leeyeehoo/CSRNet-pytorch](https://github.com/leeyeehoo/CSRNet-pytorch))
|
| 27 |
+
|
| 28 |
+
### Model Sources
|
| 29 |
+
|
| 30 |
+
- **Repository:** [https://github.com/leeyeehoo/CSRNet-pytorch](https://github.com/leeyeehoo/CSRNet-pytorch)
|
| 31 |
+
|
| 32 |
+
## Uses
|
| 33 |
+
|
| 34 |
+
This model was created in the spirit of creating a model capable of counting the amount of people in a crowd using images.
|
| 35 |
+
|
| 36 |
+
### Direct Use
|
| 37 |
+
|
| 38 |
+
```bash
|
| 39 |
+
model = CSRNet()
|
| 40 |
+
checkpoint = torch.load("weights.pth")
|
| 41 |
+
model.load_state_dict(checkpoint)
|
| 42 |
+
model.predict()
|
| 43 |
+
|
| 44 |
+
```
|
| 45 |
+
|
| 46 |
+
## Bias, Risks, and Limitations
|
| 47 |
+
|
| 48 |
+
Although the model can be very accurate its not exact, it has a 2%-6% error in the prediction.
|
| 49 |
+
|
| 50 |
+
## Training Details
|
| 51 |
+
|
| 52 |
+
### Training Data
|
| 53 |
+
|
| 54 |
+
The model was trained using the ShanghaiTech Dataset, specifically the Shanghai B Dataset.
|
| 55 |
+
|
| 56 |
+
### Training Procedure
|
| 57 |
+
|
| 58 |
+
The info on training procedure can be found in this repository [https://github.com/leeyeehoo/CSRNet-pytorch](https://github.com/leeyeehoo/CSRNet-pytorch)
|
| 59 |
+
|
| 60 |
+
## Evaluation and Results
|
| 61 |
