MACHINE LEARNING

INTRODUCTION

• IMAGINE A WORLD WHERE COMPUTERS CAN LEARN FROM DATA, JUST LIKE HUMANS DO.

• MEET MACHINE LEARNING (ML), THE TECHNOLOGY THAT MAKES THIS VISION A REALITY.

HOW DOES MACHINE LEARNING WORK?

• COLLECT DATA: GATHER DATA RELEVANT TO THE PROBLEM YOU WANT TO SOLVE.

• PREPARE DATA: CLEAN AND ORGANIZE THE DATA TO MAKE IT SUITABLE FOR LEARNING.

• CHOOSE AN ALGORITHM: SELECT AN APPROPRIATE ML ALGORITHM BASED ON THE DATA AND

PROBLEM TYPE.

• TRAIN THE MODEL: FEED THE DATA TO THE ALGORITHM, ALLOWING IT TO LEARN PATTERNS

AND RELATIONSHIPS.

• EVALUATE AND IMPROVE: ASSESS THE PERFORMANCE OF THE MODEL AND REFINE IT AS

NEEDED.

TYPES OF MACHINE LEARNING

• SUPERVISED LEARNING: LABELS SHOW THE COMPUTER WHAT TO LEARN.

• EXAMPLE: PREDICTING HOUSING PRICES BASED ON HISTORICAL SALES DATA.
• UNSUPERVISED LEARNING: THE COMPUTER DISCOVERS PATTERNS WITHOUT LABELS.
• EXAMPLE: GROUPING CUSTOMERS INTO SEGMENTS BASED ON THEIR PURCHASE BEHAVIOR.
• REINFORCEMENT LEARNING: THE COMPUTER LEARNS BY INTERACTING WITH ITS ENVIRONMENT.
• EXAMPLE: TRAINING A ROBOT TO PLAY A GAME BY REWARDING IT FOR SUCCESSFUL ACTIONS.

CLASSIFICATION

• CLASSIFICATION INVOLVES ASSIGNING DATA POINTS TO PREDEFINED CATEGORIES.

• IT IS USED TO PREDICT DISCRETE OR CATEGORICAL OUTCOMES, SUCH AS WHETHER AN EMAIL

IS SPAM OR NOT, OR WHETHER A MEDICAL IMAGE INDICATES A DISEASE OR NOT

REGRESSION

• REGRESSION INVOLVES PREDICTING CONTINUOUS NUMERICAL VALUES.

• IT IS USED TO MODEL RELATIONSHIPS BETWEEN VARIABLES AND PREDICT OUTCOMES, SUCH AS

PREDICTING HOUSING PRICES BASED ON VARIOUS FACTORS, OR FORECASTING SALES BASED

ON HISTORICAL DATA

EXAMPLE:

SELF
