Cellular Automata

A cellular automaton is a collection of “colored” cells on a grid of specified shape that evolves through a number of discrete time steps according to a set of rules based on the states of neighboring cells. The rules are then applied iteratively for as many time steps as desired. von Neumann was one of […]

Error-tolerant Finite-state Recognition

Error-tolerant finite-state recognition based on a research of Kemal Oflazer, enables the recognition of strings that deviate mildly from any string in the regular set recognized by the underlying finite-state recognizer. For example, suppose we have a recognizer for the regular set over {a, b} described by the regular expression (aba + bab), and we […]

Sentence Analyzer in Intelligent Systems

The Sentence Analyzer accepts sentences as input. It makes sure that the true meaning of the sentence is not lost. It parses the sentence into words, perform Lexical and Syntactic Analysis and finally transform the sentence into logical expressions for further processing.
The Sentence Analyzer uses high tech Natural Language Processing similar to this research work […]

A Simple Optimization Problem solved by Neural Network

Suppose Company A manufactures products X and Y using machines A and B. Company A has 8 hours daily operation. A can produce 200 pieces/hr with a production cost of Php 200.00/pc and 300 pieces/hr with a production cost of Php 250.00/pc for products X and Y respectively while B can produce 500/hr with a production cost of […]

Artificial Life in Space Exploration

One of the most challenging fields in modern science today is space exploration. Why do we need to go to other planets anyway? Well, it is a common thing that we are curious about what it is out there that we do not know…this motivates us to explore other worlds and it has already been […]
