## 💡 Tips and Tricks <a href="#tips-and-tricks" id="tips-and-tricks"></a>

<details>

<summary>Tuning Learning Rate</summary>

Adjusting the learning rate can significantly affect the model's convergence speed. A smaller learning rate can lead to slower convergence but may result in a better final performance, while a larger rate can speed up training but risks overshooting minima.

<details>

<summary>Experiment with Rho</summary>

Rho controls the decay rate of the accumulated past gradients. A typical value is around `0.95`, but feel free to experiment based on your dataset and model complexity.

</details>

<details>

<summary>Check Epsilon Value</summary>

Epsilon can be kept small (default: `1e-07`) to avoid division by zero issues. Only increase it if you encounter numerical instability.

## 🛠️ Troubleshooting <a href="#troubleshooting" id="troubleshooting"></a>

<details>

<summary>Incorrect Parameter Format</summary>

Ensure that the values entered for `Learning Rate`, `Rho`, and `Epsilon` are proper floating-point numbers to prevent errors during evaluation.

</details>

<details>

<summary>Optimizer Not Returning Properly</summary>

If you encounter issues while obtaining the optimizer instance, verify that all parameters are verified and formatted correctly. Adjust to dynamic range limits where necessary.
