	Objectives
	AN INTRODUCTION TO INFORMATION THEORY AND CODING FOR COMPUTER SCIENTISTS, WITH A SPECIAL FOCUS ON COMPUTER NETWORKS TOPICS AND APPLICATIONS. THERE ARE MANY CONNECTIONS AMONG ISSUES ARISING FROM COMPUTER APPLICATIONS ON ONE HAND AND INFORMATION THEORY ON THE OTHER . THE TEACHING PURPOSE IS TO EXPLORE SUCH CONNECTIONS IN ORDER TO USE THE INFORMATION THEORY TOOLS TO ANALYZE AND SOLVE VARIOUS COMPUTER PROBLEMS WITH SPECIAL ATTENTION TO THE COMMUNICATION IN COMPUTER NETWORKS. A FIRST OBJECTIVE OF THIS TEACHING IS THE ACQUISITION BY THE STUDENT OF THE CONCEPT OF MEASURE OF INFORMATION AND OF ITS APPLICATIONS TO COMPUTER PROBLEMS. THIS CONCEPT WILL ALLOW TO ANSWER QUESTIONS SUCH AS: WHAT IS THE MINIMUM (AVERAGE) NUMBER OF BITS NEEDED TO REBUILD A TEXT? THE SECOND PART OF THE LESSONS WILL BE DEVOTED TO THE ACQUISITION OF THE CONCEPT OF PROTECTION OF INFORMATION FROM ERRORS OF WRITING/READING OR TRANSMISSION. THE CONCEPTS OF CODES FOR THE CONTROL OF ERRORS ARE INTRODUCED. THE EMPHASIS WILL BE ON IDEAS AND METHODS WHICH ARE MORE USEFUL TO COMPUTER APPLICATIONS. APPLYING KNOWLEDGE AND UNDERSTANDING: THE GOAL IS TO EXPAND THE CAPACITY OF THE STUDENT TO ABSTRACT FORMAL ISSUES AND TO PLAN INFORMATION-THEORETIC SOLUTIONS STARTING FROM REAL COMPUTER PROBLEMS.

	Prerequisites
	MAIN PROBABILITY THEORY CONCEPTS

	Contents
	MAIN TOPICS: INFORMATION MEASURES (ENTROPY, MUTUAL INFORMATION), DATA COMPRESSION (OPTIMAL CODES, LEMPEL-ZIV CODING), TRANSMISSION OVER NOISY CHANNELS (CHANNEL CAPACITY, CHANNEL CODING), ERROR-CORRECTING CODES (LINEAR CODES, CONVOLUTIONAL CODES), AND THEIR APPLICATIONS.

	Teaching Methods
	CLASS LESSONS

	Verification of learning
	ACHIEVEMENT OF THE TEACHING OBJECTIVES IS CERTIFIED BY PASSING AN ORAL EXAMINATION. THE ORAL TEST IS AIMED AT ENSURING THE LEVEL OF KNOWLEDGE AND UNDERSTANDING SKILLS GAINED BY THE STUDENT, AS WELL AS TO VERIFY THE EXPOSURE CAPACITY USING THE APPROPRIATE TERMINOLOGY AND THE ABILITY TO INDEPENDENTLY ORGANIZE THE EXPOSURE OF THE ARGUMENTS.

	Texts
	THE TEACHING MATERIAL WILL BE PROVIDED BY THE TEACHER
