The result is not convincing! #1

Hi!

I tested your app and got accuracy of prediction is about 50%. So... not good :)

26hzhang commented 6 years ago

@adignatov Oh, I'm sorry, but it is just a plain version of stock price prediction, I create it just for practice, not really expect it can give good results for all requirements. But the data I test in the resources folder seems OK. So you use you own data? if the result is not good, I guess it is better to change some hyper parameters, and also, this app I got some good result in Open, Close, Low, High prices, not for Volume.

@adignatov Here is the training information and the predicted graph I did just now for your reference. And I see the dataset I have again, maybe for some of them, you can not get really good results, since here are few data of the stock available in the dataset.

To understand if prediction works or not, you need to compare last test value with predicted value and real value. If direction of real and predicted values will be the same, prediction correct. Am I right?

Does this program predict the price of the next day? Looking at the program i feel it predicts stock price only of those stocks whose actual stock price is given and not the next day stock price?

leodennis commented 6 years ago

I agree, he is predicting only one day ahead at a time, because he is not taking the prediction as input for the next prediciton, but the actual value.

This results in a lag of the actual signal, all your network has to do is produce a similar value to the last input of the price.

If you would take your prediction as the input for the next prediction you would see that the results are quite bad!

Still if changed correctly you can use this example for actual predictions, but maybe not stocks because they won't be good...

This is what is happening if you take predicted values as input for the next prediction: real
