Artificial Intelligence 5/3/10

Artificial Intelligence (AI) relies on intelligence agents.

It should be able to set goals and achieve them by itself, not be programmed to do it.

Some countries are generally nonreligious, therefore they are not concerened about ethical issues reguaring AI and robotics.

They want machines to be able to learn the more you use it. Ex. Youtube's "recommended for you " videos

luguage processing

Motion and manipulation

perception: Sense and percieve

Social Intelligence(for making friends :) )

1. One would argue he did what he was trained to do through  a murder simulator. 

Or it is only a game and it will not effect him negatively but  teach him hand-eye coordination. This game may not have triggered him stealing car but another force within him.

2.This case is not likely to happen again. This game has been out for years and no one playing the game has reacted so extreme due to this game.

"The video game industry gave him a cranial menu that popped up in the blink of an eye, in that police station," says Thompson. "And that menu offered him the split-second decision to kill the officers, shoot them in the head, flee in a police car, just as the game itself trained them to do."

3. Before having violent video games sold to minors, one should make  sure the minor is emotionally and psycological stable and should maybe have parental consent before purchasing the game.

4.Video game designers do play a role in violent crime, because with video games such as GTA a player is trained to kill a person without consequences like it would be the same in reality.

"the teenage brain is different from the adult brain. The impulse control center of the brain, the part of the brain that enables us to think ahead, consider consequences, manage urges -- that's the part of the brain right behind our forehead called the prefrontal cortex"

Social impact of reliance on simulations to examine issues of public policy

Social impact of reliance on simulations to examine issues of public policy

It is relatively difficult to study the effects from public policy on people are using technology. Most, if not all computer simulations are not able to capture the affect of public policy on society, through human nature, or their likes or dislikes. A computer simulation designer must be sure their computer simulation accurately captures human behavior. Human behavior is subjective and there is no universal standard for how human behavior should be simulated in technology.
For example, Today, with interest rates decreasing, banks are able to invest more, which leads to more investments, which results in a flourishing economy. This is not 100% accurate at simulating economical undulations based on human behavior and their buying and selling, but through statistics and the mathematical aspect, computer simulations, simulating the economy are relatively accurate.
Also one can argue, there is a difference of opinion on using government money to send oversees to poverty-stricken countries. Although it may be helping one country it may be “negatively” impacting another. This issue is subjective and no accurate computer simulation can be accurately created from this fact.
Although simulations can help study the effects of public policy to make it easier for policymakers to understand the positive or negative effects of their policies, due to subjectivity, it is difficult to full paint and accurate picture through a simulation. Some computer simulations also may be based off of incorrect information, resulting in harmful laws created by policy makers.
The following is from the Public News Health Center.
“Many scientists and public health experts believe that a global pandemic caused by a deadly and highly contagious flu virus is likely one day, if not inevitable. However, computer simulations of an influenza outbreak in Southeast Asia show that a global pandemic might be averted with a prompt public health response, such as targeted geographic use of prophylactic anti-viral drugs and policies to reduce social contact, such as quarantines or temporarily closing schools and businesses. The analysis is published in the August 3, 2005, edition of Nature.”

Review Q and Discussion Q #1 p.134

What is the relationship between a program and an algorithm?
A program is written in a language that a computer can understand it is a set of computer instructions designed to solve problems. An Algorithm is a set of step-by-step procedures for accomplishing a task.


In what way is writing instructions for a computer more difficult than writing instructions for a person? In what way is it easier?

A computer already has a set language and with algorithms, can fix any ambiguities or problems. It may be more difficult because you would have to use "machine language" which is numeric codes that initiate computer operations.

E-commerce is important in today's business world becuase it makes it easier for people to carry out business transtactions. It increases productivity by providing faster transsactions and is more efficient.E-Commerce has a large impact on comsumers and is allowing consumers to become pore dependent on internet transactions and it does not require leaving the house for business purposes.

E-commerce (B2B) and extranet allows for the sharing or intraorganizational information and allows buying and selling between businesses. At a college or university, buisness alliances can be formed to buy and import recsources from one school to another. These resources can include bokks and office supplies. The extranet can facilitate orders between differenct companies and are more efficient becuase of easy communication between businesses. Links can be installed and advertised on the university website for more business and money opportuities.

Depending on the amount of extra money paid I would pay extra for more secure buisness transactions and to prevent the sharing or personal information. I don't think I would share personal information even if it did promise personalized service.

IB Practice Q

Computer based translators often do not translate correctly because during translation words and meanings are lost and the contrext of the word is not taken into consideeeration while translating. A word may be translated but the meaning may be completely different becuase of the context it was placed in.The meaning of a word before it was translated may not have the same quality or emphasis after becuase some languages may not exactly have the same word or phrase.
MArkup language is a keyword that is shown or marked after it was searched.

Review Questions #2/4

Why is it hard to estimate the extent of computer crime?
Many computer crimes go undetected and unreported becuase businesses fear if computer crfimes are detected thay would lose more from negative publicity than the actual crime. businesses do know that instituions lose billions of dollars every year to computer criminals.

What is the most common computer crime? Who commits it? What is being done to stop it?
Theft is the most common form of computer crime, computers are used to steal money, goods, information and computer resources.

Examples of people that have commited computer crime are intruders who broke into a credit card website, the company has created a safer website.
two Russian men were arrested for breaking inteo several US Company networks.

Many computer users today face a growing problem of hacked files and emails, proving passwords are just not enough.  New technologies have emerged as a solution to this poblem such as  security questions  aupon accessing your network  or biometric technology that may scan  physical features. These techniques which are now used by  many people continue to grow  ad develope and serve as a solution to these social and ethical issues such as security or  reliability issues.

What are the different levels of access to the internet?

The levels  that one can access the internet by are categorized by scope and scale. 

There is WAN which stands for Wide Area Network, which can reach many house and has alarger  connection range. Then there is MAN - Metropolitan Area Network, which can reach " a  couple" ofhouses.

Then LAN (LOCAL AREA NETWORK) for the  private   household  computer
