  ## Use Cases
288
 
289
- `bert-mini` is designed for **edge and IoT scenarios** with constrained compute and connectivity. Key applications include:
 
 
 
 
 
 
 
 
 
 
 
290
 
291
- - **Smart Home Devices**: Parse commands like “Turn [MASK] the light” (predicts “on” or “off”).
292
- - **IoT Sensors**: Interpret sensor contexts, e.g., “The [MASK] barked loudly” (predicts “dog” for security alerts).
293
- - **Wearables**: Real-time intent detection, e.g., “She wore a beautiful [MASK]” (predicts “dress” for fashion apps).
294
- - **Mobile Apps**: Offline chatbots or semantic search, e.g., “The train arrived at the [MASK]” (predicts “station”).
295
- - **Voice Assistants**: Local command parsing, e.g., “He used a [MASK] to hammer” (predicts “hammer”).
296
- - **Toy Robotics**: Lightweight command understanding for interactive toys.
297
- - **Fitness Trackers**: Local text feedback processing, e.g., sentiment analysis.
298
- - **Car Assistants**: Offline command disambiguation without cloud APIs.
299
 
300
  ## Hardware Requirements
301
 
302
- - **Processors**: CPUs, mobile NPUs, or microcontrollers (e.g., ESP32, Raspberry Pi)
303
- - **Storage**: ~15MB for model weights (quantized for reduced footprint)
304
  - **Memory**: ~60MB RAM for inference
305
  - **Environment**: Offline or low-connectivity settings
306
 
307
- Quantization ensures efficient memory usage, making it suitable for microcontrollers.
308
 
309
  ## Trained On
310
 
311
- - **Custom Dataset**: Curated data focused on general and IoT-related contexts (sourced from custom-dataset). This enhances performance on tasks like command parsing and contextual understanding.
 
312
 
313
  Fine-tuning on domain-specific data is recommended for optimal results.
314
 
315
  ## Fine-Tuning Guide
