In Topic: can i predict future data using a data history?

03 August 2013 - 01:49 AM

To answer the question of the title - you can't really predict the future based on past patterns and history, but, you can build probabilities of events happening if similar patterns emerge...

 

Basically, many stock predictors work on this model - some with surprising accuracy, however there is no good way to account for unforseen events, hence, you can only really build probabilities of what may occur. Of course the more event data you have, the more accurate of a model you can build.

 

Now, going about actually creating a program for this - you'll want to look into a number of AI techniques probably starting with neural network theory. 

 

Any specific ideas in terms of exactly what sort of data and/or events you are interested in? Or, is it more or less of just a curiosity?


In Topic: woes + questions about getting a bad credit score :/

17 May 2011 - 09:25 PM

Eghad - that seems a bit odd - I'd immediately recommend getting a full credit report so you can see what all you have in your name. Typically on the report as well, they have a good view of what payments were missed and to whom, as well as who's looked into your credit.

I'd look for a couple of main things:

First - on the credit report - are there accounts for which you don't remember, or can't remember opening? If so - you may have (unfortunately) fallen victim to identity theft, and thus, will need to work with the agencies to help restore your credit and lock down your personal information.

Second, if none of the accounts seem foreign to you, how many times have you applied for a credit card or loan within the past year and were denied? If you've applied to only a couple of places, fine, but the more you apply and are rejected, this can have a negative impact on your score.

Finally, the more revolving credit (i.e. credit cards) with low balances to high limits you have the better... a $1,000 limit isn't that high and will not help much - who knows what wonky things the credit card companies have been doing over the past year to loop-hole the new federal regulations that came out, but, this might have something (although probably very little) to do with it.

Good luck!

In Topic: Recommend a book for DirectX

09 May 2011 - 08:01 PM

Please recommend a book of DirectX programming for starters.

I am not new to programming, and i have a passion for programming, game development. I am new to OpenGL (started to learn recently), so should i start learning DirectX now or gain some more experience with OpenGL before making the switch?


One of the best resources I've had luck with Introduction to 3D Game Programming by Frank Luna (author's website link here) - pretty good theoretical basis and comes in DX9 and DX10 flavors both with an emphasis on shader work (who wants to use the FFP anymore anyhow!? :D ) There's certainly other ones out there too - as tom_mai78101 said - check the books in the resources section on this site - good place to start...

As for OpenGL / DirectX - in my view, they're really 2 sides of the same coin -- so, once you learn one, it's fairly easy to go back to apply your knowledge to the other... my 2 cents.

In Topic: Experimentation and Doubt

04 May 2011 - 10:12 PM

I have this re-occurring problem when designing my projects at an intermediate level; it seems I can't make "big" decisions without a lot of doubt creeping up all the time, which is taking away time that I could've actually spent doing stuff!


I've been having a lot of the same problem recently -I'll come up with some "grand idea" in my head and rush to my workstation, fire up the IDE... then - nothing. After a few minutes of blankly staring at the screen, start to doubt and analyze (and probably over-analyze) my original thought processes for the idea, and never actually do it.

One thing that I've started doing that has helped is instead of rushing into coding (or whatever) - I've been committing the thoughts to paper first. Along with this, making 2 columns for pros and cons, and for each con scribbling down alternatives to get around those rough spots. From this, I've noticed that when I am ready to start coding, I at least have a rough plan of where I want to take things and can focus a bit better at reaching that goal.

Good luck!

In Topic: Memory allocation in changing a struct to a class...

You should be able to change the offset of all of your vertex type declarations so that the first element (position, probably) starts at offset 4 instead of 0, but I'm not sure if D3D will spit warnings out at you for doing that (You are using the debug runtimes, right?)


Ah, yes - that would be the most easy solution to try... and that worked out perfectly... and yes - debug runtimes are my friend... ;)

That article about vtables was nice - thanks for the reference...

Thanks both - rate++!
