## 🚀 Overview

This model is a **fine-tuned MoViNet (Mobile Video Network)** on the **Kinetics-600 dataset**, specifically adapted for **RunAsh Live Streaming Action Recognition** — a real-time video analytics system designed for live platforms (e.g., Twitch, YouTube Live, Instagram Live) to detect and classify human actions in low-latency, bandwidth-constrained environments.

MoViNet, developed by Google, is a family of efficient 3D convolutional architectures designed for mobile and edge devices. This version uses **MoViNet-A0** (smallest variant) for optimal inference speed and memory usage, while maintaining strong accuracy on real-world streaming content.

✅ **Optimized for**: Live streaming, mobile inference, low-latency, low-power devices  
✅ **Input**: 176x176 RGB video clips, 5 seconds (15 frames at 3 FPS)  
✅ **Output**: 600 action classes from Kinetics-600, mapped to RunAsh’s custom taxonomy  
✅ **Deployment**: Hugging Face Transformers + ONNX + TensorRT (for edge)  

---

## 📚 Dataset: Kinetics-600

- **Source**: [Kinetics-600](https://deepmind.com/research/highlighted-research/kinetics)  
- **Size**: ~500K video clips (600 classes, ~700–800 clips per class)  
- **Duration**: 10 seconds per clip (we extract 5s segments at 3 FPS for efficiency)  
- **Classes**: Human actions such as *“playing guitar”*, *“pouring coffee”*, *“doing a handstand”*, *“riding a bike”*  
- **Preprocessing**:  
  - Resized to `176x176`  
  - Sampled at 3 FPS → 15 frames per clip  
  - Normalized with ImageNet mean/std  
  - Augmentations: Random horizontal flip, color jitter, temporal crop  

> 💡 **Note**: We filtered out clips with low human visibility, excessive motion blur, or non-human-centric content to better suit live streaming use cases.

frame_rate: 3
use_fp16: true
```

✅ **Training Environment**: NVIDIA A10G (16GB VRAM), 4 GPUs (DataParallel)  
✅ **Training Time**: ~18 hours  
✅ **Final Validation Accuracy**: **76.2%** (Top-1)  
✅ **Inference Speed**: **~45ms per clip** on CPU (Intel i7), **~12ms** on Jetson Orin

## 🎯 RunAsh-Specific Customization

To adapt MoViNet for **live streaming action recognition**, we:

1. **Mapped Kinetics-600 classes** to a curated subset of 50 high-value actions relevant to live streamers:
   - `wave`, `point`, `dance`, `clap`, `jump`, `sit`, `stand`, `drink`, `eat`, `type`, `hold phone`, `show screen`, etc.
2. **Added custom label mapping** to reduce noise from irrelevant classes (e.g., “playing violin” → mapped to “playing guitar”).
3. **Trained with class-weighted loss** to handle class imbalance in streaming content.
4. **Integrated temporal smoothing**: 3-frame sliding window voting to reduce jitter in real-time output.

## 📦 Usage Example

```python
from transformers import pipeline
import torch

# Load model
pipe = pipeline(
    "video-classification",
    model="runash/runash-movinet-kinetics600-live",
    device=0 if torch.cuda.is_available() else -1
)

# Input: Path to a 5-second MP4 clip (176x176, 3 FPS)
result = pipe("path/to/stream_clip.mp4")

print(result)
# Output: [{'label': 'clap', 'score': 0.932}, {'label': 'wave', 'score': 0.051}]

# For real-time streaming, use the `streaming` wrapper:
from runash import LiveActionRecognizer

recognizer = LiveActionRecognizer(model_name="runash/runash-movinet-kinetics600-live")
for frame_batch in video_stream():
    action = recognizer.predict(frame_batch)
    print(f"Detected: {action['label']} ({action['score']:.3f})")
```
