Outline: Introduction History of artificial intelligence Methods use to create Intelligence Neural networks and Parallel Computation Applications of AI Conclusion


Introduction Artificial Intelligence (AI) is the area of computer science focusing on creating machines that can engage on behaviors that humans consider intelligent. Today with the advent of the computer and 50 years of research into AI programming techniques, the dream of smart machines is becoming a reality. Researchers are creating systems which can mimic human thought, understand speech, beat the best human chess player, and countless other feats never before possible .

History of artificial intelligence :

History of artificial intelligence Branch of computer Science that deals with intelligent behavior, learning, and adaptation in machines Man behind AI

Slide 5:

Alan Tuning stated that a computer would deserves to be called intelligent if it could deceive a human into believing that it was human. Norbert Wiener was one of the first Americans to make observations on the principle of feedback theory

Neural Networks and Parallel Computation :

Neural Networks and Parallel Computation

Slide 7:

A pplications …

Natural Language Processing:

Natural Language Processing Gives Machines the ability to read and understand the languages human being speak. Some straight forward applications of natural language processing include information retrieval and machine translation.

Speech Recognition:

Speech Recognition Speech Recognition : It is a technology that allows the computer to identify and understand words spoken. The ultimate goal of the technology is to able to produce a system that can recognize with 100% accuracy all words that are spoken by any person.

Slide 10:

Now you can speak to your computer and it can speak back. In other words you can’t just ask your computer how he/she is feeling? Rather, you can talk to your computer using a set of pre-defined commands and instruction(i.e., script). Your computer will respond in the same way(also using script language). For Example, you can say: “File Open”, and the computer would respond: “select the file”. Or you can say: “edit Find ” and the computer would ask: “Find What?”.

Software's Available::

Software's Available: Dragon Naturally Speaking App Xvoice Speech Recognition Open Mind Speech IVOS Speech vibe 2.0.4 Fake Voice 1.691

Game Playing::

Game Playing: Chess AI-based game playing programs combine intelligence with entertainment. World-champion chess playing programs can see ahead twenty plus moves in advance for each move they make. Chess programs do not play chess as humans do. In three minutes, Deep Thought (a master program) considers 126 million moves.

Slide 13:

Tetris Tic Tac Toe Computer Chess Age of Empires And Many more…

Facial Recognition System:

Facial Recognition System Computer applications for automatically identifying or verifying a person from a digital image or a video frame from a video source.

Handwriting Recognition:

Handwriting Recognition Handwriting recognition is the ability of computer to receive and interpret intelligence handwritten input. The image of the written text may be sensed “off line ” from a piece of paper by optical scanning(optical character recognition). Alternatively, the movements of the pen-based computer screen surface.

High-performance fighter aircraft::

High-performance fighter aircraft: In these programs, speech recognizers have been operated successfully in fighter aircraft with application including: setting radio frequencies, commanding an autopilot system, setting steer-point coordinates and weapons release parameters, and controlling flight displays


Robotics Robotics is the science and technology of robots and their design, manufacture and application Intelligence is required for robots to be able to handle such task as object manipulation and navigation, with-problem of localization, mapping and motion planning.

Robotics Applications::

Robotics Applications: Outer space Military Hospitals Farms Disaster Areas Entertainment

Technology Behind Robots::

Technology Behind Robots: Sensors: They uses sensors and intelligent algorithms to avoid obstacles and navigate stairs. Microcontroller systems: Intelligent electronic devices used inside robots

Example :pick and place task on Robot::

Example :pick and place task on Robot: Move to P1(a general safe position) Move to P2(an approach to p3) Move to P3(a position to pick the object) Close gripper Move to P4(an approach to P5) Move to P5(a position to place the object) Open gripper Move to P1 and finish

Expert Systems :

Expert Systems Expert system Knowledge engineer Domain expert Knowledge user

Slide 23:

Inference engine Explanation facility Knowledge base acquisition facility User interface Knowledge base Experts User Architecture of Expert System


Determining requirements Identifying experts Construct expert system components Implementing results Maintaining and reviewing system Expert Systems Development Domain The area of knowledge addressed by the expert system.

Advantages of Expert Systems :

Advantages of Expert Systems One can view entire reasoning process Easy to develop and modify Development by knowledge engineers and users It acts as a good problem solver and tutor

Limitations of Expert Systems:

Limitations of Expert Systems Not widely used or tested Limited to relatively narrow problems Cannot readily deal with “mixed” knowledge Possibility of error Cannot refine own knowledge base Difficult to maintain May have high development costs Raise legal and ethical concerns


Future: Chandrayaan-II will be launched by 2012. It will have a Lander that will droop a small robot on moon, which will pick samples, analyze data and send the data back. Bristled robots will help clean pipes. Love and Emotion. Human will themselves be implanted with microchips


conclusion Throughout the presentation I was discussing about how the technology is enhanced using artificial intelligence in all the fields , In feature humans will be driven by machine performing functions with accuracy where human power doesn’t require any Industry .
