Synthetic data generation
Closed this issue · 1 comments
When I implement this with the stock data, the generated synthetic data is not so good. For example, opening price of a day should be very close to the closing price of the previous day. However, for some days I do not observe this pattern.
Did you actually generate synthetic data for stock dataset? If yes, can you also share your generated data?
...opening price of a day should be very close to the closing price of the previous day. However, for some days I do not observe this pattern.
I think it would be normal that "some days" would have the poor results that you mentioned for a few reasons.
- The hyperparameters were not optimized for this dataset.
- I don't think the evaluation metric (TSTR) would be sensitive to this issue. Therefore, there is a possibility that the model generated these "noisy" examples.

Unfortunately, I did not save my results on the stock data, as I am using it for other purposes.
You could try to generate samples using the original implementation here. Hope this helps.
