Pattern recognition in Intro to Computing - Flowchart & Logic Diagram

Process Overview

Pattern recognition is the process where a computer or person identifies regularities or repeated sequences in data. It helps in making decisions or predictions by spotting familiar shapes, numbers, or behaviors.

Input data

This flowchart shows the step-by-step process of pattern recognition: starting with input data, checking if data is available, analyzing it, deciding if a pattern is found, outputting the pattern if yes, or looping back to input if no.

Step-by-Step Trace - 6 Steps

Step 1: Start and input data sequence: 2, 4, 6, 8, 10

Step 2: Check if data is available

Step 3: Analyze data for regularities

Step 4: Decide if a pattern is found

Step 5: Output the pattern found

Step 6: End process

This diagram shows how the data sequence is stored in memory, then passed to the pattern recognizer component which analyzes it, and finally outputs the recognized pattern.

Key Result

Pattern recognition works by checking data step-by-step to find repeated rules or sequences, then outputs the discovered pattern.
