Small problem in MulAdd #18

Closed Pigrecos closed 4 years ago

Pigrecos commented 4 years ago

If I run the XorAndOr example in delphi (or by disabling AVX support in Lazaurus) I get errors while calculating the output of the last layer.

TVolume.MulAdd procedures (Value: T; Original: TVolume); begin {$ IFDEF Debug} if Original.Size <> Self.Size then raise Exception.Create ('Sizes don''t match at MulAdd:' + IntToStr (Self.Size) + 'and' + IntToStr (Original.Size) + '.'); {$ ENDIF} MulAdd (Value, Addr (Original.FData [0])); end;

Throws the exception which is not the case with AVX.

thank you

Backpropagation was trying to calculate errors for the input layer (this was the cause of the problem). Please let me know if this fix works at your end. Thank you very much for reporting!

now works very well. Thank you
