Chapter 15 4RQ

1) Describe several techniques used in game-playing software and explain how they can be applied to other AI applications?

• Searching
• Heuristics
• Pattern recognition
• Machine learning

2) Why did early machine translation programs fail to produce the desired results?
The early machine translation failed because the computer did not know the translation.

3) What rules might a computer use to sort the characters shown on page 597 into As and Bs?

1. If the engine will not turn over and the lights do not woek then check the battery.
2. If checking the battery shows it is not dead then check the battery connectors

4) What is the relationship between syntax and semantics?Can you construct a sentence that follows the rules of English syntax but has nonsense semantics?
Syntax means "word order" and Semantics means "meaning". Word order affects meaning.
         Example: Dogs bites man. Man bites dog.

Chapter 15 DQ

1- Is the Turing test a valid test of intelligence? Why or why not?
The Turing Test is carried out by engaging a human judge in a conversation between a human and a machine. I do not believe that it tests if you are intelligent or not because the computer is a machine. It is programmed for the purpose of getting answers. If you beat the computer then OH YA your intelligent :) but if you dont its an honor just to be able to compete with a computer. It doesn't mean you are dumb or dont understand something if you dont win the competiton against the computer.

2- List several mental task that people do better than computers. List several mental tasks that computers do better than people. Can you find any general characteristics that distinguish the items of the two lists?

Brain

• uses chemicals to transmit information
• Memories grow by stronger synaptic connections.
• It is much easier and faster for the brain to learn new things.

Computer

• uses electricity
• uses switches that are either on or off (binary)
• memory grows by adding computer chips
• the computer can do many complex tasks at the same time (multitasking)

Ch 15 4RQs

1) In what sense is AI a "moving frontier"?
If a task is easy to do for a computer many scientists believe that it is not artificial intelligence. This definition is what make it a moving frontier.

2) What distinguishes a robot from a desktop computer?
The most important hardware diffferences between a robot and other comps are the input and output peripherals. Instead of sending output to a screen or a printer a robot sends commands to joints, arms, etc.

3) What are some of the problems that make machine vision so challenging?

• masses of irrelevant data
• objects that partially cover objects
• indistinct edges
• changes in light source and shadow
• changes in the scene as objects move
• etc...

4) What is the knowledge base? What is an expert system? How are the two related?
Knowledge base: contains a system of rules for determing and changing the relationship among facts
Expert system: a software program designed to replicate the decision making process of a human expert
Knowledge bases lie at the heart of every expert system used in business, science, and industry.

Ch 13 DQ second one

You are planning on starting your own business selling clothes. Discuss pros and cons for starting an e-business.

Pros
- you can manage it yourself
- you are your own boss
- it is more reliable(in some ways), controled, secure, private, and you can choose who you want to access it

Ch 13 4RQ

1) What is the purpose of an extranet? What are the main characteristics of an extranet?
            An extranet extends the cross-functional activites between trusted business partners and facilitates their working relationship. Characteristics are secure private network, public network, and virtual private network (VPN).

2) List the capabilities of e-commerce software should provide.

• Increasing the speed of B2B tranactions
• reducing errors on intercompany
• reducing costs of telecommunication
• increasing the volume of business with partners
• exchanging B2B docs
• checking on inventory and order status from supplies
• collaborating with business partners on joint projects

3) What are purposes of an intranet? What are the main characteristics of an inranet?
           Most intranets use Ethernet topology to cnnect physically the comps, printers, and other hardware on the network. Characteristics of an intranet are

• Contained: Typically a network (LAN) within an organization
• Shielded: Offers the "common language" of internet without the loss of privacy of the Internet
• Gated: Can be connected via gateways to selected Internet content or access
• Functional: a fully operational network for organization-wide communication, information, and interaction

4) Describe some ethical issues involved in electronic commerce.

• a statement of the oranization's privacy policy
• a statement that a persons permission must be secured before his or her ID, photo, ideas, or communication are used or trransmitted
• a statement on how the company will inform customers of the intended uses of personal info gathered during an online transaction and how to secure permission from customers for those uses
• a statement that address issues of ownership with respect to network postings and communications
• a statement of how the company monitors user behavior on the web

CH 13 DQ

If someone discovers a cure for the common cold, should he or she hide it to protect the jobs of all
the people who work in the huge cold-medicine industry? Identify reasons why so many people react negatively to advances in technology that eliminates some jobs.

I think that if someone discovers a cure than they should spread it around. If they really care about money so much that they dont want others to get the idea then they could copyright it in some way and then sell it. People will by it and everyone gets the common cold so a lot of people will want it so they will become rich.

Some reasons why people react negatively to advanced technology are because if there is a reason for people to lose their job they wont be able to provide for their family, they wont be "rich", they will have a hard life, might lose their job, etc.

Take Home Mock Test

a) Two other physical characteristics are palm print and iris.

b) We can authenticate an identity in three ways first by something a user knows (password) second something a user has (smart card) and third something a user is (face, fingerprints). When a person puts any of these things in a system and wants to be authenticated the biometric features are re-scanned then they are matched with information in database and then it is either authenticated or rejected.

c) It is better to have biometric options for payments at retail stores than to have a signature for a credit card becuase people put their signature on almost anything now. A lot of people lose their credit cards and anyone can just find a persons signature and practice forging it. But if a retail store had people give their fingerprints or something than  that would NOT be easy to seal. Fingerprint authentication has a 99% accuaracy rate because the only way for someone to be able to steal your identity is by getting close to you and you will surely notice then or copy it from the machine but then they might get caught or more than one persons identity mixed in so that would probably not work.

d) Some concerns that people might have if biometric authentication became widespread are one identity theft if images of fingerprints are stolen than criminals can easliy use then to steal identities.Second  physical concerns for example if someones iris is exposed to a lot of technology because stores want authentication that could easily lead to eye disease. Third is privacy personal information could be sold to other organizations without the persons knowlege or consent. Fourth is integrity because since their is human input into the system mistakes could happen and the system might have some problems in it There are many more concerns but these are just a few.
