Our intended audience are all people that work or plan to work in Data Analysis, starting from motivated high school students. So this formula allows us to compute binomial coefficients. Next, we will apply our knowledge in combinatorics to study basic Probability Theory. Besides this, keep in mind that your intensive study and initial reading must be done alone as you are the only one who can understand your own problems and analysis where you stuck while solving the problems. First, we study extensively more advanced combinatorial settings. We know that n choose k is equal to n factorial divided by k factorial multiplied by n minus k factorial. If it is carnivore, then we go again left, and we ask whether it hunts at night, and then we separate owls from eagles. Can we do anything better than just list all the objects? So by the rule of thumb, we have n minus 1 choose k minus 1 plus n minus 1 choose k testing sets in total. Especially enjoyed learning the theory and Python practical in chunks and then bringing them together for the final assignment. Recurrence relation and mathematical induction. So why is this so? [MUSIC] We start discussing graphs with easier specific case of graph, which is called a tree. Coursera Course: Introduction to Discrete Mathematics for Computer Science by University of California, San Diego & National Research University Higher School of Economics WP = What is a Proof? Graphs can be found everywhere around us and we will provide you with numerous examples. They are similar to university courses, but do not tend to offer academic credit. n choose k is equal to n factorial divided by k factorial multiplied by n minus k factorial and actually the exactly same expression we have for n choose n minus k. Okay. You can also do this in graph theory, and the root vertex can be picked arbitrarily. to get access to your one-sheeter, Discrete Mathematics and Its Applications, Discrete Mathematics and Its Applications, 7th Edition, Recursive Definitions and Structural Induction, Generalized Permutations and Combinations, Divide-and-Conquer Algorithms and Recurrence Relations, Graph Terminology and Special Types of Graphs, Representing Graphs and Graph Isomorphism, Axioms for the Real Numbers and the Positive Integers. Even though, at various universities, an undergraduate course with discrete mathematics is mandatory to pursue a degree in computer science subjects. In the first week we have already considered most of the standard settings in Combinatorics, that allow us to address many counting problems. Let's provide the proof of this theorem by direct calculation. Probability is everywhere in Data Analysis and we will study it in much more details later. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. We are accessible for 24*7, and all your assignments are available at a reasonable price. WEEK 1Basic CombinatoricsSuppose we need to count certain objects. Various topics under discrete math involve focusing on executions, algorithms, and efficiencies. supports HTML5 video. What does this mean? In some settings, we need to separate a testing dataset from our dataset to use in the following way. Also, we address one more standard setting, combinations with repetitions. Applications of graphs include geoinformational systems (vertices are cities, edges are roads), social network analysis (people and friendship relations), chemistry (graphs of molecular structure), computer network topology, and many more. More questions? So we want to separate the testing data set of size k. How many ways do you have to do it? Video created by National Research University Higher School of Economics for the course "Discrete Math and Analyzing Social Graphs". The second gaol of the course is to practice counting. Okay. So the theorem states that a tree on n vertices always have n- 1 edges. Okay. We will start with a brief introduction to combinatorics, the branch of mathematics that studies how to count. Probability is everywhere in Data Analysis and we will study it in much more details later. This will help you to solve the problem more effectively. So the parent is the only vertex that goes on the path towards the root, and all other vertices are children. Thanks to all the professors, teachers, staffs and coordinators for making this course so interesting. First, we study extensively more advanced combinatorial settings.
