Here's a table with concrete examples illustrating when to use different types of neural networks – RNNs, LSTMs, and GRUs:
| Scenario | RNN | LSTM | GRU | Explanation |
|----------|-----|------|-----|-------------|
| Short Sequences | ✅ | ❌ | ❌ | RNNs are efficient for short-term dependencies, making them suitable for short sequences. |
| Long Sequences with Complex Dependencies | ❌ | ✅ | ✅ | LSTMs and GRUs are designed to handle long-term dependencies effectively. |
| Limited Computational Resources | ❌ | ❌ | ✅ | GRUs, being simpler than LSTMs, are more computationally efficient. |
| Real-time Processing | ✅ | ❌ | ✅ | RNNs and GRUs are faster, making them better for real-time applications. |
| Time-Series Analysis | ✅ | ✅ | ✅ | All can be used, but LSTMs and GRUs are preferable for long-range forecasts. |
| Text Generation | ❌ | ✅ | ✅ | LSTMs and GRUs excel in handling the complexity of language for text generation. |
| Speech Recognition | ❌ | ✅ | ✅ | The ability to remember long-term features makes LSTMs and GRUs ideal for speech recognition. |
This table provides a general guide; the best choice depends on the specific requirements and constraints of your project.
