Yes, I know that it is impossible to predict lottery results. But if the results would be predictable? Of course I know they are not, but just hypothetically for a play with Perceptron Neural Network and prediction algorithms I want to show you that in 245 lines of code you are able to play with prediction thanks to Encog 3.3 library. I bought recently 2 Jeff Heaton’s books about neural networks and C# and his library. That inspired me to play with prediction, forecast, trends, classifications, regression and more… I do not want to bring you too much details and I wan to share that 245 lines of code. To make it working in Visual Studio you have to just download by NuGet encog-dotnet-core 3.3 library and include it to console application with that code, then last thing to prepare is recent results of power ball lottery let’s said from last year and safe that as the TXT file. But please remember, predicted values are correct in math but it is impossible to predict truly random lottery results which is Power Ball, but who can stop me from trying ;-). There is one more thing, having good results can take some time, sometimes few hours, so be patient when you run it. To make it faster I made it stop once 40% results are predicted correctly. Thanks for reading!

Have you perhaps got a vb.net version of this?

Hi. Thanks for the sharing. I have a question. What does variable deep is for in the code? and also what it should be to cover all lines? Thanks
@”C:\Projects\Predictor\db\winnums-text.txt”;
help ? please email ? thank you
I get
System.IndexOutOfRangeException: Index was outside the bounds of the array.
please help
