XOR Using Neural Networks

XOR Engine
10.6 It's a “Network,”

Exclusive disjunction, also called exclusive or (symbolized by the prefix operator J, or by the infix operators XOR, EOR, EXOR, ⊻ or ⊕, is a logical operation on two logical values, typically the values of two propositions, that produces a value of true only in cases where the truth value of the operands differ.

The above explanation is taken from wikipedia. It describes an XOR operation as only returning a true value when there is a difference between the operands. Thus the ‘XOR Engine’ can be read as the ‘Difference Engine’.

A Difference Engine is one of several partly built mechanical computers designed by Charles Babbage in the 1800s. Babbage is considered one of the fathers of the modern computer.

‘The Difference Engine’ is also the name of a Steampunk novel written by William Gibson and Bruce Sterling. The novel describes an alternate history in which Babbage succeeds in building his mechanical computer, the computer then sees widespread use and the possible socioeconomic effects this technological revolution could have on a 19th century Britain.

Gibson is one of my favourite authors. Gibson is credited with coining the term “cyberspace” and envisioning the future importance and power of the internet. His debut novel “Neuromancer” has been described as “the archetypal cyberpunk work”.

Wrong-way greenspan

2005-03-28 14:24:28 by nobullnobear

Greenspan has a multi-decade history of being dead wrong at key economic inflection points, dating back to the 1970s.
Yes, he warned of “irrational exuberance” in the stock market in 1996, but did everything in his power to keep the bubble blowing by pouring tons of liquidity into the money supply during the Asian currency crisis of 1997, the LTCM crisis of 1998 and the faux Y2K crisis of 1999. Nor did he make any attempt to raise margin requirements to rein in wanton speculation. He marked the top on 3/6/00 (the same week the Nasdaq peaked at 5,100 with his speech before the Boston College Conference on the New Economy (excerpted):
“In the last few years it has become increasingly clear that this business cycle differs in a very profound way from the many other cycles that...

Commercial real estate in free fall?

2002-11-10 07:41:36 by sam_n

November 5 Fitch – “The number of defaulted commercial mortgage-backed securitizations (CMBS) loans with losses will increase in 2002 by over 100% and the severity of these losses will increase by at least 50%, according to a new report published today by Fitch Ratings. As of year-end 2001, the loss severity increased to 34% from 19% as of year end 2000. These data come from the latest Fitch CMBS loss study, which considers a universe of 28,116 loans in conduit, large loan, and fusion CMBS transactions rated by Fitch as of year end 2001 but excludes single borrower transactions. ‘With fundamentals deteriorating in many real estate markets and a greater volume of loans in workout, Fitch expects losses will continue to rise during 2002.'”
