Building a AI in Autoit

Recommended Posts

FMS

Hello,

I'm building whit mine limited coding know-how :) a AI in Autoit....
Just because..... why not :ILA2:

It's not doing what i tought it would do.

I hope somebody could help me whit this script?

so far :

-building an learning grid --> AI needs to guess the label in the grin whit only the X and Y value.
-Building an array filled whit random values as weights.
-quess the label
-learn - if quess not the same as the label go change the weights

At this point (the changing of the weights) I've some strange result and hope somebody could point me in the right direction
I think that the problem is in the formula for changing the weights.

PS. I'm also open for good coding practice ;)  I'm learning coding as i go ;)

Neural Networks is the most slow and complex algorithm of AI Development (There are also variations that can be more or less complex)  in my opinion.


To calculate weights you must have special algorithms suited for ur purpose and ur database properties (I deduce you are trying to build a Chatbot), i can't really tell what the problem in ur code is, i am not really skilled in those type of areas, however, i'm pretty sure a shorter algorithm for building neurons would work fine. 

 

What makes Neural Networks complex:

Spoiler

each sentence is broken down into different words and each word then is used as input for the neural networks. The weighted connections are then calculated by different iterations through the training data thousands of times. Each time improving the weights to making it accurate. The trained data of neural network is a comparable algorithm more and less code. When there is a big sample, where the training sentences have 20450 different words and 2450 classes, then that would be a matrix of 20450×2450. But this matrix size increases by n (X number) times more gradually and can cause a huge number of errors. In this kind of situations, processing speed should be considerably high, that would cause ur Artificial Intelligence to work slower with the time, that's the reason why i think Neural Networks is the most complex.

 

Let me know if you fixed your problem!

      Hello,
       
      I am currently writing a program that parses a massive table from a website, and need a way to add a progress bar while parsing.
      I am currently using the function _IETableWriteToArray($oObj, True) to parse the array. I need the progress bar to update as the table is parsed, not just at the end of the parsing.
      Any help at all would be very much appreciated!
       
      *EDIT --> The array I am left with after parsing is $array[0-50000][16]

      So Im trying to make a simple 2d game and make some sort of collision detection so why not to make a 2 dimensional array but i have no clue how  to write it in multiple lines
      Global $map[5,5] = [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0 _ [0,0,0,0,0] something like this but it doesn't work

      #include "..\Include\Array.au3" #include "..\Include\File.au3" #include "..\Include\AutoItConstants.au3" Local $aRetArray Local $sFilePath = "n.csv" _FileReadToArray($sFilePath, $aRetArray, ",") ; _FileReadToArray($sFilePath, $aRetArray, $FRTA_COUNT, ",") _ArrayDisplay($aRetArray, "Original", Default, 8) The above code shows two versions of _FileReadToArray and both don't work as expected.
      The first one doesn't use the comma as a delimiter. (so I get a single column array)  I tried adding "Default" between $aRetArray and "," then it told me it had an incorrect number of parameters. 

      I looked again at the documentation:
       
      #include <File.au3> _FileReadToArray ( $sFilePath, ByRef $vReturn [, $iFlags = $FRTA_COUNT [, $sDelimiter = ""]] )
      And I with or without the flags params I should be getting a 2D array due to my file being a csv. 
      I then tried a regular flag, $FRTA_COUNT, and it tells me that I'm using a variable $FRTA_COUNT while it's not declared. Tried putting in 1 instead and it told me again, incorrect number of params.

      Hi,
      Recently I have had the need to do a sort and then do a second sort while the item of the first sort stays the same ( double sorting , first on column x then while column x is the same sort column y).
      I did not put much efffort into error checking but so far I did not need it.
      For my applications so far it works perfectly however if someone is willing I want to test this extensivly.
      If anyone has big lists of random stuff to sort could you try this out please?

      So I've made this script that detects how long i have held down my left mouse button for and stores the information in an array and then sorts its using _ArraySort but the output is half sorted half broken.
      Here's my script:
      HotKeySet("{F1}","_exit") #include <Misc.au3> #include <Timers.au3> #include <Array.au3> Local $dll = DllOpen("user32.dll") $on = False Global $array[0] While(1) If _IsPressed(01,$dll) Then $timer = _Timer_Init() While _IsPressed(01,$dll) Sleep(1) WEnd $time = _Timer_Diff($timer) _ArrayAdd($array,"Time: " & Floor($time) & " ms") ;~ ConsoleWrite("Time: " & Floor($time) & " ms" & @CRLF) EndIf Sleep(50) WEnd Func _exit() _ArraySort($array) _ArrayDisplay($array) Exit EndFunc And the output:

      See how its not sorted?  What is the problem here?
