JSlider You use the JSlider in applications to allow for a change in a numerical value. It's a quick and easy way to let users visually get feedback on not only their current choice, but also their range of acceptable values. If you think about it, you could provide a text field and allow your user to enter a value, but then you'd have the added hassle of ensuring that the value is a number and also that it fits in the required numerical range. As an example, if you have a financial Web ...

What is JDBC? JDBC stands for Java Database Connectivity, which is a standard Java API for databaseindependent connectivity between the Java programming language and a wide range of databases. The JDBC library includes APIs for each of the tasks commonly associated with database usage:  Making a connection to a database  Creating SQL or MySQL statements  Executing that SQL or MySQL queries in the database  Viewing & Modifying the resulting records

 Blind Searches have no preference as to which state (node) that is expanded next  The different types of blind searches are characterised by the order in which they expand the nodes.  This can have a dramatic effect on how well the search performs when measured against the four criteria we defined in an earlier lecture

AI Course Overview The course provides students with basic knowledge of the theory and practice of Artificial Intelligence as a discipline concerning intelligent agents capable of deciding what to do and doing it. The material covered includes search algorithms, knowledge representation and reasoning, as well as a brief introduction to several sub-fields of AI. The course objectives are: ° To have an appreciation for and understanding of both the achievements of AI and the theor...

1. Given the following propositions: p: Peter is driving his own car. a: Andrew is late. m: Max has caught the bus. (a) Write each of the following in symbols: (i) Andrew is late and Peter is driving his own car. (ii) Either Max has caught the bus or else Andrew is late. (iii) Either Peter is driving his own car and Andrew is late or else Max has not caught the bus. (iv) Peter is driving his own car and either Andrew is late or else Max has caught the bus. (v) Max has caught the bus b...

”Modification of a behavioral tendency by expertise.” (Webster 1984) • ”A learning machine, broadly defined is any device whose actions are influenced by past experiences.” (Nilsson 1965) • ”Any change in a system that allows it to perform better the second time on repetition of the same task or on another task drawn from the same population.” (Simon 1983) • ”An improvement in information processing ability that results from information processing activity.” (...

Expert systems  Diagnosis e.g. MYCIN  Generate alerts and reminders  Therapy critiquing and planning  Knowledge management  Doctors rely on at least 2 million facts and clinical knowledge doubles every 20 years.

The syntax:  Vocabulary:  A set of propositional symbols - e.g., P, Q, …  A set of logical connectives or operators  usually  (OR),  (AND), ¬ (NOT),  (implication), maybe  (equivalence), Parenthesis (for grouping)  The special symbols  True, False (logical constants)

Expressiveness of natural language:  Very expressive, probably everything that can be expressed symbolically can be expressed in natural language (pictures, content of art, emotions are often hard to express)  Probably the most expressive knowledge representation formalism we have. Reasoning is very complex, hard to model Problems with natural language:  Natural language is often ambiguous.  The syntax and semantics are not fully understood.  There is little uniformity...

 Some issues:  Search trees grow very quickly  The size of the search tree is governed by the branching factor  Even this simple game tic-tac-toe has a complete search tree of 984,410 potential nodes  The search tree for chess has a branching factor of about

An over-used, over-loaded, and misused term.  Anything that can be viewed as perceiving its environment through sensors and acting upon that environment through its effectors to maximize progress towards its goals.  PAGE (Percepts, Actions, Goals, Environment)  Task-specific & specialized: well-defined goals and environment  The notion of an agent is meant to be a tool for analyzing systems, not an absolute characterization that divides the world into agents and non-agents...

 A goal directed agent needs to achieve certain goals. Such an agent selects its actions based on the goal it has.  Many problems can be represented as a set of states and a set of rules of how one state is transformed to another.  Each state is an abstract representation of the agent's environment.  It is an abstraction that denotes a configuration of the agent.  Initial state : The description of the starting configuration of the agent.  An action/ operator t...

Humans can be looked upon as agents. They have eyes, ears, skin, taste buds, etc. for sensors; and hands, fingers, legs, mouth for effectors. 2. Robots are agents. Robots may have camera, sonar, infrared, bumper, etc. for sensors. They can have grippers, wheels, lights, speakers, etc. for actuators. Some examples of robots are Xavier from CMU, COG from MIT, etc. 3. We also have software agents or softbots that have some functions as sensors and some functions as actuators. A is an ...

 Game playing is not like this.  The opponent introduces uncertainty.  The opponent also wants to win  Game Playing has been studied for a long time  Babbage (tic-tac-toe)  Turing (chess) 

In our discussion of the rationality of the simple vacuum-cleaner agent, we had to specify the performance measure. the environment, and the agent's actuators and sensors. We group all these under the heading of the task environment. For the acronymically minded, we call PEAS this the PEAS (Performance, Environment, Actuators, Sensors) description. In designing an agent, the first step must always be to specify the task environment as filly as possible The vacuum world was a simple exa...

Given this scenario different interpretations have been used by different researchers as defining the scope and view of Artificial Intelligence. 1. One view is that artificial intelligence is about designing systems that are as intelligent as humans.  This view involves trying to understand human thought and an effort to build machines that emulate the human thought process.  This view is the cognitive science approach to AI. 2. The second approach is best embodied by the con...

SCO105 DATA COMMUNICATION COMPUTER NETWORKING ( Course Outline )

The Internet is one of the most important developments in the history of both information systems and communication systems because it is both an information system and a communication system. The Internet was started by the U.S. Department of Defense in 1969 as a network of four computers called ARPANET. Its goal was to link a set of computers operated by several universities doing military research. The original network grew as more computers and more computer networks were linked to it. ...

The objective of the course is to enable the student apply a high level language for solution of simple scientific problems, and for this purpose to manipulate the inputs/outputs of a computer Programme using Object Oriented Programming Techniques. Objectives At the end of the course a student is expected to: • Know all the high level language representation of mathematical functions • effectively use the different data types and variables, viz., numbers, character, and logical variable...

Java is platform independent. This means that it will run on just about any operating system. So whether your computer runs Windows, Linux, Mac OS, it's all the same to Java! The reason it can run on any operating system is because of the Java Virtual Machine. The Virtual Machine is a programme that processes all your code correctly. So you need to install this programme (Virtual Machine) before you can run any Java code. Java is owned by a company called Sun Microsystems, so you need to head ...
