Bayesian neural networks example
The future of software may lie in the obscure theories of an 18th century cleric named Thomas Bayes.
By LESLIE HELM, Times Staff Writer
When Microsoft Senior Vice President Steve Ballmer first heard his company was planning to make a huge investment in an Internet service offering movie reviews and local entertainment information in major cities across the nation, he went to Chairman Bill Gates with his concerns.
After all, Ballmer has billions of dollars of his own money in Microsoft stock, and entertainment isn’t exactly the company’s strong point.
But Gates dismissed such reservations. Microsoft’s competitive advantage, he responded, was its expertise in “Bayesian networks.”
Asked recently when computers would finally begin to understand human speech, Gates began discussing the critical role of “Bayesian” systems.
Ask any other software executive about anything “Bayesian” and you’re liable to get a blank stare.
Is Gates onto something? Is this alien-sounding technology Microsoft’s new secret weapon?
Bayesian networks are complex diagrams that organize the body of knowledge in any given area by mapping out cause-and-effect relationships among key variables and encoding them with numbers that represent the extent to which one variable is likely to affect another.

I will give you the benefit of the doubt. But some of your statements I respectfully disagree,
First you constantly cite zero sum game as if that is the end all argument to say no one can make money in the market. Your view of the market is too narrow. You cannot state from your living room that forex is a zero sum game because you do not know what is involved in a transaction. Investment bank A can buy Euros and sell dollars to cover a short Euro position that was profitable from Investment Bank B who is opening a short position in Euro. There is no zero sum because one is an opening transaction and one is a closing transaction. This continues 24 hours a day on and on and there is no final end tally. Everyone can make or lose money on a given day and with the use of hedging tools...

Big Banks Are Ripping Off Pension Funds2011-08-19 08:53:30 by -
"Attorneys general in Virginia and Florida filed civil suits against BNY Mellon alleging that the bank cheated pension funds in those states by choosing improper prices for currency trades the bank processed for the funds," The WSJ reports. "The Virginia lawsuit, filed in a Fairfax, Va., state court, cites internal bank emails allegedly showing that senior bank officials knew about, and endorsed, a currency-trading method that hurt state pensioners."
In addition to Virginia and Florida, California and Tennessee are also suing BNY Mellon and State Street Corp. over the alleged fraud.
The man who uncovered the alleged scam, Harry Markopolos, expects all 50 states to eventually join the suit. If the name sounds familiar that's because Markopolos was a whistleblower on the...

Ill give you a few lessons I learned after working at FXCM, trying to trade forex, and then trying to daytrade professionally on two separate occassions and losing both times. This cost me a full year of my time and about $25,000. Im glad I did it when I was young, however.
So, here we go:
1. Forex trading does not work. Trading on a delayed feed with a bucket shop (the houses rules) on excessive leverage is gambling pure and simple. If you have a longer-term thesis about the currency market and want to INVEST in that, fine. Thats investing. However, be sure to not lever up too much otherwise whether you are right or wrong wont matter much as youll get shaken off.
2. Daytrading does not work. Spreads are tight and markets are efficient. The day of of the US...
