Principles of Data Mining by David J.Hand, Heikki Mannils, Padhraic Smyth
The growing interest in data mining is motivated by a common problem across disciplines: how does one store, access, model, and ultimately describe and understand very large data sets? Historically, different aspects of data mining have been addressed independently by different disciplines. This is the first truly interdisciplinary text on data mining, blending the contributions of information science, computer science, and statistics.The book consists of three sections. The first, foundations, provides a tutorial overview of the principles underlying data mining algorithms and their application. The presentation emphasizes intuition rather than rigor. The second section, data mining algorithms, shows how algorithms are constructed to solve specific problems in a principled manner. The algorithms covered include trees and rules for classification and regression, association rules, belief networks, classical statistical models, nonlinear models such as neural networks, and local “memory-based” models. The third section shows how all of the preceding analysis fits together when applied to real-world data mining problems. Topics include the role of metadata, how to handle missing data, and data preprocessing.
What is forex?
Quite simply, it’s the global market that allows one to trade two currencies against each other.
If you think one currency will be stronger versus the other, and you end up correct, then you can make a profit.
If you’ve ever traveled to another country, you usually had to find a currency exchange booth at the airport, and then exchange the money you have in your wallet into the currency of the country you are visiting.
Foreign Exchange
You go up to the counter and notice a screen displaying different exchange rates for different currencies.
An exchange rate is the relative price of two currencies from two different countries.
You find “Japanese yen” and think to yourself, “WOW! My one dollar is worth 100 yen?! And I have ten dollars! I’m going to be rich!!!”
When you do this, you’ve essentially participated in the forex market!
You’ve exchanged one currency for another.
Or in forex trading terms, assuming you’re an American visiting Japan, you’ve sold dollars and bought yen.
Currency Exchange
Before you fly back home, you stop by the currency exchange booth to exchange the yen that you miraculously have left over (Tokyo is expensive!) and notice the exchange rates have changed.
It’s these changes in the exchange rates that allow you to make money in the foreign exchange market.
