Recent Transformations in Data Mining Techniques

By definition, practitioners in multidisciplinary fields such as bioinformatics need to keep abreast of the latest research trends in several areas. However, the relevance of research work focused in areas outside their normal specialty may not be immediately obvious to all observers.

For instance, a multi-million dollar, 4-year research project on statistical methods for data mining, called Euredit and funded by the European Union, is creating interesting possibilities for many bioinformatics endeavors, including microarray analysis and forecasting trends.

Euredit’s goal was to analyze census surveys. Due to human nature, these surveys usually contain missing or incorrect data. European governments funded research to determine and improve statistical techniques that can be used to clean this data by filling in gaps or highlighting errors. This research was carried out by government national statistics offices, universities, and research-based companies. The cleaned data produced by this research was then used to better estimate the need for services and programs in communities. The result of this intensive research study was a number of new algorithms relevant to disciplines where data mining is important, with bioinformatics perhaps one of the top beneficiaries.

Financial Information Cleaning

Increasingly, sophisticated methods are available for analyzing financial data and helping decision makers. Many of these methods have been described in articles that have appeared in Financial Engineering News. But in practice the data that will be used by these methods can be full of errors; it is dirty data. And it is often the more sophisticated methods that are most affected by dirty data, time series and variance models, such as GARCH, seem to be particularly sensitive to the presence of bad values in the data. While it is sometimes possible to use robust techniques that are less sensitive to bad observations, for example, using a median instead of a mean, it makes sense to deal with the bad data before the modeling takes place. Improve the quality of the data and you are very likely to improve the quality of the results. So before using the data it should be cleaned, that is, as many of the errors in the data as possible are corrected.

Here we will look specifically at cleaning numerical information, but the need for data cleaning is perhaps more important in text information where problems with misspelling and use of different abbreviations etc. complicate the process further.

What can be wrong with the data? There is a hierarchy of problems that are encountered:

1. No values have been input

2. Impossible values have been input

3. Inconsistent values have been input

4. Unlikely values have been input

While the first seems straightforward, there needs to be a distinction made between structural missing and observational missing. Structural missing will relate to values you would not expect to be there, for instance, share price changes will not be available when stock markets are closed at weekends or holidays. The models used need to be able to cope with such values, inventing values to fill such gaps is not a good way to proceed. On the other hand, observational missing are just values that have gone astray. Clearly where possible they should be looked for, but this may either be impossible or just too expensive.

Real Estate Statistics Understanding

Nearly everyone has heard or read a story lately regarding the climate of the real estate market. It is important to remember that real estate is locally driven, sometimes differentiated all the way down to a specific or unique neighborhood. Statistics used to describe the state of the national real estate market do not bear the same weight or the same meaning on many local markets.

The best source for statistics about current home prices and trends in any region is the local Multiple Listing Service, or MLS. A Multiple Listing Service is a cooperative of real estate brokerage firms. The MLS maintains a robust database containing a consolidation of property listings submitted by member brokerages over many years. It is available to all member brokers and their agents and provides a fast, effective way to list, view and market properties and conduct market analysis, benefiting both the buying and selling public as a whole.

Market statistics provided by the MLS are explained through the use of terminology, such as median, mean, and percentage change. Here is a look at some simple and easy to understand definitions of these terms. A median, the most frequently used and cited statistical measure in real estate, is simply the middle value of a set of numbers. In other words, it is the exact point at which half of the values are higher and half are lower. With home prices, the median is the exact sales price where 50 percent of the homes sold for less than the reference price and 50 percent sold for more. A median is especially relevant when discussing home prices, because it is not influenced by extremely high or extremely low prices. Read the rest of this entry »

Industial Automation and Its Use

Automation or Industrial Automation  is the use of computers to control industrial machinery and processes, replacing human operators. It is a step beyond mechanization, where human operators are provided with machinery to help them in their jobs. The most visible part of automation can be said to be industrial robotics. Some advantages are repeatability, tighter quality control, waste reduction, integration with business systems, increased productivity and reduction of labour. Some disadvantages are high initial costs and increased dependence on maintenance.

By the middle of the 20th century, automation had existed for many years on a small scale, using mechanical devices to automate the production of simply shaped items. However the concept only became truly practical with the addition of the computer, whose flexibility allowed it to drive almost any sort of task. Computers with the required combination of power, price, and size first started to appear in the 1960s, and since then have taken over the vast majority of assembly line tasks (some food production/inspection being a notable exception).

In most cases specialised hardened computers referred to as PLCs (Programmable Logic Controllers) are used to synchronize the flow of inputs from sensors and events with the flow of outputs to actuators and events. This leads to precisely controlled actions that permit a tight control of the process or machine. Read the rest of this entry »

Credit Card Consolidation – The Risks Involved

When you have amassed quite a huge amount of credit card debts, you can look at credit card debt consolidation as a means to manage your debts.

Creating of Internet Marketing Texts with SEOP.com

Search engines are the most effective layout area for web advertisement. There are two main reasons for that:

1. Search engines are the only kind of sites that users visit with a desire to find something to move on as soon as possible.
2. As far as search engines know what users are looking for, they can target advertisements to the current task of searching for a user. The appearance of ads that a user needs at this very moment is much more effective than targeted advertising, formed on the basis of personal data of consumers. Such advertising can be created for you by many internet marketing companies, such as SEOP.com.

Such advertising is especially good in Google search engine. As far as it uses text-only ad units, users are more likely to pay attention to them than to graphic banners that they can mechanically ignore. Moreover, it may resonate with consumers disposed to reading advertisements, because of small volume of their text ads that are clearly formulated in Google. Read the rest of this entry »

President Obama: “We will make BP pay for the damage”

US President Barack Obama is due to meet BP executives after vowing to make the oil company pay for the Gulf of Mexico oil spill.

In his first TV address to the nation as president, Mr Obama said he would tell BP’s chairman the firm must set up a fund to compensate those affected.

Oil has been leaking into the Gulf since a drilling rig leased by BP blew up on 20 April, killing 11 workers.

BP has been accused of failing to follow proper procedures.

As oil has washed ashore in Gulf coast states, affecting businesses and wildlife, the rhetoric from US politicians has become increasingly bitter and the firm’s share price has tumbled, with billions of dollars being wiped off its value.

Mr Obama invited BP chairman Carl-Henric Svanberg to the White House meeting. The Associated Press news agency quotes BP as saying that group chief executive Tony Hayward, BP America president Lamar McKay and managing director Robert Dudley will accompany Mr Svanberg.

It will be Mr Obama’s first face-to-face meeting with them since the oil leak began.

“I will meet with the chairman of BP and inform him that he is to set aside whatever resources are required to compensate the workers and business owners who have been harmed as a result of his company’s recklessness,” Mr Obama said in his address from the White House’s Oval Office.

“And this fund will not be controlled by BP. In order to ensure that all legitimate claims are paid out in a fair and timely manner, the account must and will be administered by an independent third party.”

In response to the speech, BP said in a statement that it shared Mr Obama’s goal of cleaning up the oil spill and helping the people affected by it. Read the rest of this entry »

Sudan elected as president Bashir sought

KHARTOUM (Reuters) – President Omar Hassan al-Bashir won the first open election in 24 years in Sudan, a result that confirms the position the leader wanted for war crimes by the International Criminal Court. Abel Alier The election official told a news conference that Bashir did 68 percent of the votes of the presidential election, while Salva Kiir, president of the semi-autonomous southern region, won reelection with 92.99 percent of votes in the contest. After a vote that international observers said fell short of global standards, is expected to form a coalition with Bashir Kiir while country is heading for a plebiscite in 2011 which could lead to a separation of southern Sudan and become a new state. Bashir hoped a victory in legitimate elections could help to challenge request of the International Criminal Court, which is accused of ordering a campaign of murder, torture and rape in the Darfur region of Sudan. But the vote was marred by accusations of fraud, including claims of the People”s Liberation Movement of Sudan, Kiir, suggesting that a new coalition could be very fragile. Bashir appeared on state television shortly after the result known saying that the Sudanese people “moral victory achieved in the eyes of the world in a civilized manner and class.” The president added that the referendum will be held in the south “as planned” .

Developing nations want climate pact by 2011 deadline

Ministers of Environment of the block called BASIC-Brazil, South Africa, India and China, met in Cape Town to assess how to be expedited to such an agreement to reduce global warming. “The Ministers believe that a legally binding would result in Cancun, Mexico in 2010, or up in South Africa in 2011 “they said in a joint statement, referring to UN climate talks.

Jairam Ramesh, Minister of Environment and Forests of India, told reporters: “At this point it seems that we will return to Cape Town in 2011. There is no progress in sight … we have a long way “.

Kyoto Protocol, the U.S. has not ratified, binds about 40 developed nations to cut emissions in the period 2008-12. The UN meetings on climate have failed to achieve a legally binding agreement over what happens after 2012. More than 100 countries have endorsed a nonbinding agreement, agreed last year Copenhagen, to limit global warming to below 2 degrees Celsius over pre-industrial times, but did not explain how this should be achieved.

Arizona law controversy threatens to convulse in the U.S. immigration debate

“There”s a lot, but have to happen properly. If this becomes something party, we will all lose out,” says Bob Sakaniwa, associate director of the Lawyers Association of migration issues.

Arizona Governor Jan Brewer on Friday signed SB 1070, for the first time U.S. forces from state police to identify and detain illegal migrants.

some 460,000 undocumented immigrants live in Arizona, a state bordering Mexico.

Living and working in the United States without papers is already a crime, but federal level. Dozens of police districts have signed agreements with the federal government to serve as immigration officers, but only from other crimes. The new law Arizona requires the police to stop people from “reasonable doubt” that may be illegal. If they do, they can be sued by citizens of the state. The law is “irresponsible,” Barack Obama criticized the president, who announced he will ask the Justice Department to examine whether it violates civil rights. “The American people deserve a comprehensive and judicious reform,” Obama said. The tension surrounding t1000he events in Arizona has dangerous consequences, analysts and experts involved in the discussions being Washington. Only one Republican Senator Lindsay Graham, is currently negotiating with another Democrat, Chuck Schumer, a possible text for reform, based on a program of temporary work permits, fines and obligation to learn English for those who seek legalization and identification cards. For the Democrats, whose electoral prospects in November are announced tough, the temptation is to break the deck and present a text reform itself, as they did with the reform of health services or banking.
