WHAT IS PATTERN?

PATTERN : PATTERN IS A SET OF PHYSICAL OBJECTS WHERE THE ELEMENTS OF THE SET ARE SIMILAR TO ONE ANOTHER IN CERTAIN WAYS.[1]

TYPE OF PATTERNS: [1]

SPATIAL PATTERNS:TEMPORAL PATTERN:ABSTRACT PATTERNS:

PATTERN RECOGNITION:

THE IDEA OF PATTERN RECOGNITION: [6] HUMAN PERCEPTION: [2]

PATTERN RECOGNITION:

PATTERN RECOGNITION: Is the science for how machines can: [6]– Observing (sensing) the environment, – Learning to distinguish patterns ,– and making sound decisions about the patterns or

pattern classes.RECOGNITION PATTERN WAYS: [9]

WHAT IS A PATTERN CLASS (OR CATEGORY)?[10]

SUPERVISED LEARNING: [4] Examples: [5]• The Perceptron learning algorithm,
