Artificial Neural Networks Review

The parallels between TDD derived code and Artificial Neural Networks
Neural network with four I'd like to draw an analogy between artificial neural networks and the code that often gets produced by poor TDD, i.e. TDD done with little respect paid to refactoring.

Artificial Neural Networks

An artificial neural network (ANN) is a graph like structure that maps some set of inputs to a set of outputs. The ANN can make very complex mappings due to having multiple layers and weightings between nodes in the network.

One example of an ANN is one which can recognise a human face. To obtain such a network one stimulates a randomized network with samples of a face and of non-faces. For each sample the network will produce an output. One takes the output and calculates the difference between it and the desired output and then that difference is back propogated through the network. Back propogation of the 'error' causes the network to learn, to produce smaller and smaller errors.

After training one has a very useful tool that can classify things sometimes more accurately than a human can. The faustain bargain one has agreed to is this: One doesn't know how the network classifies its input. The 'knowledge' is just a bunch of numbers, it's a black box.

Code produced by TDD

With TDD the tests take the same role as input to the code and expected output. The developer takes the difference in actual and expected output and back propogates changes to reduce this difference to zero.

I would be happy to, but someone asked me that before, and when I answered, it was flagged. I am not sure, but I think that stock traders don't like Forex trading.
I am not sure why that is. The Forex market is much bigger, and it is recession proof. There will always be banks and businesses trading money. Chrysler, last year, made more money trading Forex than they did selling vehicles. This market is also less risky, with enormous liquidity, and no slippage. Forex has low transaction costs, much higher leverage, and low account minimums.
I just think you need to know what you are doing, and for most of us, it takes education. I didn't go and work in a hospital until I went to nursing school, and prepared myself. I wouldn't risk my money until I learned how to trade it....

It's true

I was just flipping through and noticed your post. Yes, it is true about Forex. The absolute best way to get started is go to the Forex website and download the trial version of their program. It works in real time with a start of $10000 dream cash. You get to invest it how you like and see the results just like real money. The trial version is good for 30 days I think.
If I were in your shoes and never tried Forex, I would invest time into your local bookstore and read the most up-to-date books on Forex, and trading. If you jump into it both feet first and don't know what you're doing, you'll probably lose the farm.
I must also say that the trading books seem very confusing at first if you've never Forex'd before. Just read the book in it's entirety. Try the trial period...

A lot of people have said what they do here

I don't know what you're talking about.
Read the threads. There are tons of folks who have said exactly what type of work they do from home.
I am a marketing consultant specializing in Internet Marketing education and training. I also dabble in high-return investing (DaySurfing) and currency trading, like ecurrency exchange and Forex.
There are also lots of people here who are representatives for different companies who sell various products online and off. They usually include their referral links, so it's easy to find those people and exactly what they're selling.
There's a guy trying to start a motorcycle repair business from home. People who transcribe things for a living. Others who import/export, or sell stuff on eBay.
There are several artists...

FOREX

I am trading Forex, from the computer at my home. I am making several thousand a week, but I am only trading one lot. Several friends who have more money than I are trading more lots, and are making way more money than I.
It is good for me, and I am building my account, and when I have more money, I will trade more lots.
It is not something you can just go and do, you have to learn about it, or you will waste your time and your money.
I studied for about six weeks, and during that time, I practiced on a demo account.
I took live classes online, and they were great. You can take them as many times as you like. I paid $2000 for the beginners and advanced classes, but you can start with $995 for the beginners class. I figured it is less than I would spend for a...

FOREX signals svc that works GREAT 4 me but..???

2009-04-10 18:53:13 by supertrader3

Hey.. james here.. ive been trading now primarily in forex for about 3 1/2 years.. and for the past 6 months ive been using a signals service that has worked incredibly well for me, especially when compared to 2 other bogus services ive tried.. i've made a pretty significant amount of money with it..it's spot on accurate probably 95% of the time... so I trust the integrity of these people.. but my question is, im thinking about upgrading my membership to the diamond edition, which enables me to use a new autotrade service they are now offering, which basically supposedly takes all these accurate signals and trades them for me all automatically, like a robot.. this carries a monthly membership fee of of just under 100 dollars... the only reason i havent done it yet is because i know...
