[FEATURE] <description>Incorporate Time-Series Cross-Validation Support

[VaishnaviChelagola]

Is this a unique feature?

• I have checked "open" AND "closed" issues and this is not a duplicate

Is your feature request related to a problem/unavailable functionality? Please describe.

The stock price prediction model currently uses "train_test_split" to randomly split data, which might not be the best method for time-series data. The sequential nature of time-series stock data is ignored by this approach, which may result in data leakage and inaccurate model evaluation.

Proposed Solution

In order to enable the model to split the data sequentially, I wanted to add  "TimeSeriesSplit" from scikit-learn. This approach maintains the temporal order by guaranteeing that training is done on past data and evaluation is done on future data.

Do you want to work on this issue?

Yes

If "yes" to above, please explain how you would technically implement this (issue will not be assigned if this is skipped)

I'll change the  dataset splitting procedure to make advantage of 'TimeSeriesSplit' and tweak the model training to accommodate multiple splits. In order to demonstrate how 'TimeSeriesSplit' enhances model performance on stock price data, I will also present comprehensive comparison metrics (such as RMSE and MAE) before and after the implementation.
Steps:
1.Modify the data splitting logic to use TimeSeriesSplit.
2.Train the model on each split and calculate evaluation metrics.
3.Compare the results with the current random data split method.
4.Provide detailed documentation on how this feature improves the accuracy of predictions on time-series data.

@rohitinu6 Sir, I have raised an issue for the project, but as a beginner to open source, I'm not sure what the next steps are. This is my first contribution, and I would appreciate guidance on how to proceed. If there is any guide or resource you can provide, that would be really helpful. I have many doubts, such as whether I need to write the code for my issue first and then submit a pull request, or if I should pull the request first and code later. Thank you in advance for your assistance and guidance.
